In late years aging in my country lets affection of motor function such as osteoporosis by alteration such as a bone or articular cartilage, osteoarthritis of spine, osteoarthritis increase. Therefore be aimed for improvement of rich quality of life in health, and the living habits that took in sports are spreading broadly. However, with increase and aging of the action population, locomotorium injury such as a fracture, ligamentous breakdown, a cartilage injury increases again, too. A treatment of such a locomotorium disorder is one of a future medical problem. It is important to return attribute of locomotorium, configuration, a physical characteristic to an as possible original physiological state.
I study organism material replacing it in a bone, cartilage, band, arthrosis.
Study in particular medicine and science and technology studies from a confluent point of view.

    Ti 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.

    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.
