英文要約Development item Investigation of effective compound surface treatment interlayer for Nano structure control coating of metallic elasticity body. 2008 fiscal year -2009 fiscal year Report for 2008 fiscal year. Written by Asahi heat treatment KK Content and result etc. of research and development Treatise and 19 technological information investigation (attached material) accompanying 2: Verification of stress decentralization effect in interlayerThe shear stress distribution that acted on the metallic elasticity body by the contact analysis was investigated. The elasticity nitride method that is appropriate for the interlayer was decided. Survey of test methodology and test range (working scheme).The method of examining metal fatigue according to the internal shear stress generation was examined. The method of attention to the movement of a high frequency that originated in the spline in the wave motion cogwheel device of the reproduction test was examined (The PAT application is being prepared). Application use and marketing research after it achieves it of trend survey of technology concerned (result achievement and examination of effect) It turned out to be able to use this technology for the bearing structure with not good lubricated condition. It turned out to be able to apply this technology to the lifetime improvement of the machine used in the vacuum. If this technology was applied to the slurry pump, the possibility that making to high longevity was able to be achieved by improving wear and abrasion resistance turned out. Present situation of harmonic drive gearing for space and cause search of abrasion (grasp of current state and problem)In respect different from the initial wear-out side, a strong adhesion was confirmed (attached material). It has been understood for becoming familiar in contact side to continue, and to come to longevity by a rapid torque increase. It has been understood the stripe is no load initial generated in an outside center part of the wave motion generation cogwheel. Feasibility of compound surface treatment method for abrasion decrease making and investigation of the effect (examination of remedial measures)It has been understood that it is suitable to make them form an excellent [ganma-puraimu] organization in elasticity in the interlayer. The heat-treatment method necessary for the generation of the interlayer was examined, and a suitable heat treatment condition was decided. The condition of becoming basic was selected from two or more heat treatment conditions (The PAT application is being prepared). Achievement situation to performance target.It turned out that in an interlayer alone without a no tribological condition in the normal temperature atmosphere and the wearing coat, there was 18 time or more durability in the time comparison.
