The Proceedings of Mechanical Engineering Congress, Japan, 2019 J02329P, 2019Ti alloy and Co-Cr alloy are authorized as implant materials. These alloys are utilized by machining and heat treatment. The manufacturing process will generate residual stresses that influence in destruction and deformation of materials. X-Ray Diffraction (XRD) is one of methods to estimate residual stresses. However, X-ray stress constants K of some alloys have never been reported before. So when residual stresses of some alloys are measured, stress constants of pure metal are used. This case isn’t clear for evaluation of residual stresses. In this study, system to measure X-ray stress constants of alloys were constructed. Specifically, we designed and fabricated a measurement system that can irradiate X-ray to materials under load. It was confirmed that the load was uniformly applied to the test piece. So the result of loading test showed that it is possible to use this apparatus. Next, we thought about a test piece for measuring residual stress with stress constants calculated by the constructed system. Vacuum annealing was performed on the pure titanium powder and the procedure for producing test pieces in a stress-free (strained) state was confirmed.

Journal of the Japan Society of Grinding Engineers, 57(4) 235-240, Apr, 2013 Peer-reviewedIn this study, the ELID (Electrolytic In-process Dressing) polishing process was applied to a Co-Cr alloy that is used in artificial joints. The surface of the material was modified during the polishing process to give improved properties. Corrosion and wear characteristics were evaluated by the pin-on-disk testing method in a pseudo-body fluid environment. We found that a stable modified layer was formed on the surface by the ELID process, leading to improvement of corrosion resistance in friction environments.

Journal of the Japan Society of Grinding Engineers, 56(3) 184-189, Mar, 2012 Peer-reviewedThe purpose of this study was to evaluate the surface properties and corrosion behavior of Co-Cr alloys ground by Electrolytic In-process Dressing (ELID) grinding. This evaluation was carried out by abrading the alloy surfaces using ultra high molecular weight polyethylene (UHMWPE). The evaluation results showed that ELID grinding can be used to perform mirror finishing on Co-Cr alloys. ELID grinding was also applicable to create a stable modified layer, which improves corrosion wear characteristics on the workpiece surface.

The proceedings of the JSME annual meeting, 2009 265-266, 2009Two types of notched specimen of Ti-6Al-4V simulated screw configuration were prepared and cyclic fatigue test was performed in air to study fatigue property of titanium screw. Effect of heat-treatment on fatigue strength was also investigated. As a result, the specimen having a smaller notch diameter showed higher fatigue strength (N_f=10^7) than that of larger one. This result indicates that fatigue strength of notched screw can be organized with its stress concentration factor. Heat-treatment improves tensile and fatigue strength, but, endurance ratio (fatigue strength/tensile strength) become lower compared as-received materials, which supports the idea that heat-treatment affected strongly to the tensile strength not to the fatigue properties.

The proceedings of the JSME annual meeting, 2009 299-300, 2009Cobalt-Chromium (Co-Cr) alloys possess outstanding corrosion resistance and wear resistance because of passive film of a few nanometers' thickness on their surfaces. In this study, we have clarified the damage accumulation mechanism of Co-Cr alloys under the simultaneous reaction of corrosion and wear in sodium chloride solution. A corrosion wear characteristic of these alloys was evaluated by static polarization test under simultaneous wear damage. Wear was applied using a reciprocating rotational pin-on-flat abrasion machine. The pin material in all tests was polyethylene. Applied loads were 9.8 N. The disk rotation sliding rates were 10, 1.0, and 0.1 mm/s. The results show the current density increases significantly early only when the sliding rate is 10 mm/s. This is thought to occur because the wear on the passive film affects the corrosion reaction. The results also show that the current density drops (recovers) over time and approaches the Control. Therefore, if you assume the prolonged use of implants, the sliding rate in early use greatly affects the corrosion reaction.

The proceedings of the JSME annual meeting, 2007 303-304, 2007A material for medical application is required to have extended sustainability of mechanical strength together with fast bone replacement ability in human body. Composite material is preferred in the application because monolithic material does not meet the requirement. In this study, we have developed HAp/TCP composite. The mechanical property of the material is evaluated by the bending strength test. The bone replacement ability is evaluated by soaking the material in simulated body fluid (SBF). Measured result of concentration of Ca^<2+> ion in SBF indicated that the developed material has excellent bone replacement ability. The bending strength is maintained after I week of soaking in SBF due to precipitation of HAp on the surface proceeding to degrease of the strength at early stage of soaking due to dissolution of TCP.

2015 "GS0607-427-1"-"GS0607-427-3", Nov 21, 2015Barrel, 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.

2015 "OS1313-426-1"-"OS1313-426-3", Nov 21, 2015Shot 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.

2015 "OS1314-447-1"-"OS1314-447-3", Nov 21, 2015Torsion 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.
