In this research, the pair components in the steel ball and the striker plate made with Pro/Engineer of 3D・CAD, the stress distribution in the contact zone in the steel ball and the striker plate analyzed by Pro/Mechanica of CAE, and it has extracted how long depth generation of the maximum stress. As a result of the analysis, it was identify the maximum stress was generating the depth of about 100μm from the surface of the striker plate. To reduction this maximum stress, high concentration carburizing coated as a surface modification. In this result, not only high hardness surface but also the depth of about 1mm from surface obtained stable hardness and fatigue strength uplifted. Therefore, it can be said to applicatory in this environment by the thing that reduction of maximum stress generated internal and uplifted of wear resistance.
