A Study on Tribology Characteristics of SM53C by High Frequency Heat Treatment
The Cam nose part of the Automobile's Cam shaft is strongly bumped with rocker arm or valve-lift. Therefore abnormal wear such as unfair-wear and early-wear occur in the surface. This abnormal wear causes a defect that bad timing open and close actions of the engine valve happen in the combustion chamber so the fuel gas will be combustion imperfect. Therefore, the Cam shaft has to be high hardness and wear resistance. In this study, high frequency heat treatment method was accomplished for wear test for material SM53C.
