    Barrel, nozzle and screw are plasticization parts of injection molding machines that works under high processing temperature. These parts are also exposed to corrosive gas and acid environment came from molten plastics. These combined factors cause considerable corrosion damage on plasticization parts. Furthermore, frictions with glass-filled polymers in molten plastic give rise to wear damages simultaneously on plasticization parts. In this study, the electrochemical test has been conducted on SKD61 specimens in the solute H_2SO_4 dissolving nylon66-25wt.% fiberglass. It was found that oxide film formation was promoted due to the oxidation reaction between SKD61 surface and the solution while the regenerative ability of the oxide film of SKD61 was deteriorated. The corrosion wear test was also conducted by using Alumina ceramics ball on SKD61 disk specimens. Destruction of the oxide film of SKD61 due to friction was confirmed. The regenerative ability of oxide film was also verified in the test.

    Shot peening (SP) is one of the surface modification technologies to enhance fatigue strength. In this study, the mechanism of enhancement of bending fatigue property of shot peened pure titanium (JIS 2) was investigated. Surface roughness, vickers hardness of surface and subsurface, and bending fatigue strength was measured. Surface roughness and hardness of surface and subsurface were increased by SP. The bending fatigue strength was increased highly by SP because increasing of hardness effected more greatly than increasing of surface roughness. The maximum of amount of increase 2.7 times in 10^7 cycles. It was found that the bending fatigue strength was increased by increasing of hardness of surface and subsurface by SP. Therefore, it is obvious that fatigue strength of pure titanium is increased highly by SP.

    Torsion fatigue tests were conducted for circumferentially notched bars specimens of Ti-6Al-4V alloy to evaluate fatigue strength. The notch sensitivity was studied by using blunt (stress concentration factor Kt=2.0) and sharp (Kt=4.0) notched specimens. The number of cycles to failure was obtained and the crack initiation life was estimated from the applied torque to the specimens. The number of cycles to failure and fatigue strength decreased with increasing the value of stress concentration factor. When compared at the same fatigue life, the crack initiation life of Kt=4.0 specimen was much shorter than that of Kt=2.0. The crack propagation behaviors were analyzed by observing fractured surface. When stress amplitude is low, the tensile crack propagated toward a 45° direction of the longitudinal axis of the specimen, while under high stress amplitude, the shear crack propagated in the circumferential direction both in blunt and sharp notched specimens forming flat fracture surface. The fracture surface showed factory-roof pattern under middle stress amplitude. The angle of a fracture plane of the blunt notch under low stress amplitude was 45° to the axial direction. The formation of factory-roof may increase contact areas in the fractured surface, thus increase crack propagation life.

    There is a technique for 3D manufacturing the implant in the near-net-shape. To do this, we use a patient's CT image. It is a manufacturing technology by powder additive fabrication using a laser or electron beam. Additive fabrication the titanium alloy microstructure, different from that of the forged material. And, there are many defects. These defects become the origin of fatigue fracture. To use the Additive fabrication titanium alloys, fatigue properties are important. In this study, we have to evaluate the fatigue properties of titanium alloy that was shaped by an electron beam melting method. In addition, it was subjected to a surface modification for the purpose of improving the fatigue characteristics. Specifically, it was fine peening. And, the fatigue characteristics were evaluated and examined its effectiveness.

    When producing plastic products, considerable corrosion and wear on the plasticizing parts (barrels, nozzle, and screw) of injection molding machine. Corrosion gas environment resulted from molten plastic chemically reacts with surface of metals. Furthermore, wear damages are made by friction between glass-filled polymers and plasticizing parts. It is important to increase corrosion resistant and control wear damages of plasticizing parts for qualitative improvement of plastic products. Especially about corrosion, a few test methods like a immersion test by reagents are being conducted to evaluate corrosion resistance. However, in these tests it is difficult to evaluate corrosion and wear damages simultaneously. In this study, the anodic polarization test have been conducted to monitor the effect of plastic dissolved in 30wt.% H_2SO_4. And we also conducted corrosion wear test with ball on disk test. As test samples, SKD61 metal for injection molding machine and PA66+GF25% an engineering plastic are used. As a result, the regenerative faculty of oxide film on SKD61 was decreased.

    Bioactive Ti alloy for implant application has been developed by producing thin hydroxyl-apatite (HAp) film on its surface. The interfacial strength between the base metal and the HAp film has to be evaluated to ensure the reliability of the implant. But the method of evaluation is not yet established because of its difficulty to cause interfacial fracture between base metal and HAp thin film. In this study, we suggest a new testing method which is able to measure bond strength of Ti-alloy and HAp thin film. We focus on a process of preparing specimen, and evaluate bond strength between Ti-alloy and HAp thin film.

    Fretting fatigue characteristic of Ti-6Al-4V with various contact pressures were carried out using fatigue testing machine. The fretting fatigue limit of Ti-6Al-4V at 10^7cycles were σ=150MPa for CP=30, 40, 60MPa and 120MPa for CP=10MPa. In the low-cycle region (10^4-10^5 cycles), fatigue life decreases with increasing of the contact pressure. The other hand, in the high-cycle region (10^6 cycles), fatigue life decreases with decreasing of the contact pressure because of relative slip. Fretting fatigue crack initiating from contact area was observed. Then crack growth is radial.

    The powder layered manufacturing has attracted attention as a technique for producing implants in near net shape. In this study, the bending fatigue property of plane specimen of titanium alloy fabricated by means of electron beam melting method (EBM) is evaluated. The bending fatigue properties of the EBM materials subjected to fine particle peening (FPP) were also studied. The fatigue properties of EBM material was found lower than that of conventionally manufactured material because of defects introduced during manufacturing process worked as initiation sites of fracture. It was found that the surface modification process examined in this study, FPP is effective on improving the plane bending fatigue properties of EBM material. Therefore, it is believed that FPP is effective treatment.

    Torsion fatigue tests were conducted for smooth bars and circumferentially notched bars of Ti-6Al-4V alloy. The purpose of this work is to evaluate fatigue strength and notch sensitivity under stress concentration factors of Kt=2.0 and 4.0. Fatigue life and fatigue strength decrease with increasing stress concentration. To investigate the crack initiation and propagation, the crack length were calculated with Hooke's law. When compared at the same fatigue life, the crack initiation life for Kt=4.0 was much shorter than that for Kt=2.0. Difference of the fatigue fracture mechanisms between blunt and sharp notch is considered to cause this phenomenon. Under low stress amplitude, the crack propagates under tensile mode toward a 45° to the axial direction. The crack propagated all over the blunt notch, and the crack propagated in the cross section of the sharp notch root under low stress amplitude. As a result, the fracture surface of blunt notch specimen under low stress amplitude was flat, and that of sharp notch specimen showed factory-roof pattern. The formation of factory-roof increases contact areas in the fractured surface and lengthens crack propagation time.

    Artificial bone is used in the treatment of bone fractures and bone tumors. Hydroxyapatite is widely in the artificial bone. The apatite, has the ability to bind to the bone. Dense body is used to the area in need of strength. On the other hand, the porous material is used for the site reactions with body fluids such is required. However, both of the high reactivity and high strength is difficult. In this study, Fabrication of artificial bone composite of coral and HAp is the objective. The addition amount of coral is 10%. Composite artificial bone was sintered at 1300℃ 5 hours. It was possible to produce composite artificial bone. However, the sintered body was collapsed in about ten days. The reason for this is that it is fired at a high temperature. In other words, carbon dioxide elimination of coral is the cause. Furthermore, it is to the adsorbed moisture in the air. Crystal structure is changed to calcium oxide. As a structure, I expand. This is related to the collapse.

The interfacial strength between the base metal and the HAp film has to be evaluated to ensure the reliability of the implant, but the method of evaluation is not yet established. In this paper, tensile load is applied to the HAp film on Ti-6Al-4V alloy substrate nominal to its thickness by using a specimen bonded with adhesives. We improve accuracy of this method by preventing adhesive overflow from bonded surface by applying surface active agent thus avoid coverage of the interface between Ti-6Al-4V substrate and HAp film. As a result, fracture occurs at interface between Ti alloy and HAp. It means this method is useful for evaluating interfacial strength between Ti alloy and HAp.

    In 2013, the JSMS approved the formation of a task committee on interfacial strength testing to develop standard for interfacial strength in biomedical coatings test methods. This task committee has cooperated with the research committee on interfacial strength in biomedical coatings, which has been settled in the materials and processing division of JSME since 2008. The standard interfacial strength in biomedical coatings test method was discussed based on the results of round robin tests, which have done by the subcommittee in the research committee on interfacial strength in biomedical coatings, as well as the pile-upped references. The proposed test method can give reliable and reproducible test results, which can also be used for predicting interfacial strength in biomedical coatings of implant with combining crystal structure or microstructure analysis.

    The cantilever type rotating bending fatigue tests were conducted in order to investigate the effects of shot peening treatment on the fatigue property in the Ti-6A1-4V titanium alloy. Shot peening was performed with three types of fine zirconia shot grids. The fatigue lives of the shot peened specimen which fractured from inside the specimen with the fish eye on the fracture surface were longer lives than that of non-peened specimens which fractured from specimen surface. To discuss these fatigue properties, the fracture surfaces were observed and the peening effects such as surface roughness, hardness were examined. From the observation results of fish eye pattern on the fracture surface, it was clear that residual stress influences a fatigue property of Ti-6A1-4V greatly.

    Titanium alloys formed by a Selective Laser Sintering (SLS) method include many defects. In order to improve the fatigue and corrosion properties of the SLS samples, Fine Particle Peening (FPP) was introduced. When treated with high speed steel particles, almost all defects disappeared within 30 seconds of treatment. However, no noticeable effect was observed on fatigue strength and corrosion resistance of the specimen.

    The effect of notch configuration on fatigue property of beta-Ti-15Mo-5Zr-3Al alloy was studied by axial cyclic fatigue tests. Two types of notched specimen simulated biomedical screw configuration were prepared. Diameter of the specimen was 7.5mm and 5.5mm that stress concentration factor was 2.2 and 2.0 respectively. The alloy was solution treated at three different temperatures of 685℃(STA685), 735℃(STA735), and 785℃(STA785) for 60 minutes, followed by aging at 500℃ for 1000min. The effect of heat treatment on fatigue strength was also investigated. As a Result of fatigue tests, the specimen having a smaller notch diameter showed higher fatigue strength than that of larger one. This result indicates that fatigue strength of notched screw can be organized with its stress concentration factor. The tensile strength and the fatigue strength of heat-treated STA materials improved. Of the three materials, STA735 showed highest fatigue strength. It is considered that the improvement of fatigue property of Ti-15Mo-5Zr-3Al alloy is attributed to the volume fraction and the morphology of precipitate a phase.

    In this study, the effect of the shape of a notch and a circular hole on the effect of the evaluation of the plane bending fatigue property in Ti-6Al-4V was examined. Furthermore, the fracture mechanism was clarified based on the evaluation of the depth of crack from the surface. Material used in this study was a Ti-6Al-4V alloy. The used specimens are two types: notch (R=42.5mm, R=2.0mm, R=0.7mm) and circular hole (φ=20mm, φ=6mm). The plane bend fatigue testing is performed under the condition of constant displacement. The testing condition is stress ratio R=-1 and frequency 1OHz. Since fatigue test is conducted under constant displacement condition, the maximum load set at the start of the test decreases when fatigue cracking occurs. The stress distribution around the edge of a circular hole and the maximum stress (σmax) in tensile test is obtained by finite element method (FEM). In the circular hole, fatigue strength becomes lower as the diameter of the hole increase. The stress concentration factor obtained by using FEM for is Kt=6.3φ=20mm and for is Kt=3.0 φ=6mm. Therefore, the fatigue strength of the shape of a notch and a circular hole can be organized with its stress concentration factor. And the effect of the shape of a circular hole can be related to not only the maximum stress but also the stress distribution near it..

    The fatigue characteristics that simulated a bone plate having a hole were evaluated. And technique of fatigue duration of life evaluation was studied. A Ti-6Al-4V alloy and SUS316L steel were used for test materials. A specimen configuration is plate of thickness 2mm with both materials. And a penetration hole of a diameter of 2.5mm and 5.5mm, 7.5mm was emptied centrally. A stress concentration coefficient (Kt) is 2.5 and 2.2, 2.1 respectively. The fatigue test performed a uniaxial pulling fatigue test (stress ratio (R) = 0.1, frequency =10Hz, a sine wave). In addition, the examination went in atmosphere environment. A fatigue fracture was observed using SEM. In addition, by a electromagnetic field analysis (FEM), analyzed fracture stress of a hole bottom. And a fatigue fracture mechanism was considered by analyzing load distribution. Fatigue strength of a Ti-6Al-4V alloy is not associated with hole diameter, and fatigue strength is about the same. In other words it was confirmed that there was not influence by size of hole diameter. The fatigue test of SUS316L steel understood that was superior so that hole diameter was large. In addition, fatigue strength of fatigue limit (N_f=10^7 times) is superior so that hole diameter is large. It developed that this was maximum stress (σ max) and a difference of stress distribution.

    To clarify the damage accumulation mechanism of Co-Cr alloys exposed to simultaneous corrosion and wear in sodium chloride, we developed a new tribo-corrosion system and then evaluated corrosion wear characteristics of the alloys with special attention focused on the effects of scratching rate on repassivation behavior. In corrosion wear environment, higher scratching rate prevented regeneration of passive films on worn surfaces. In contrast, as compared with the conventionally polished samples, the samples ground by a new electrical grinding technique (EG-X) showed higher corrosion wear resistance.
