This experimental study investigates the fracture characteristics of the camshaft made with newly developed SM53C material. As part of the countermeasure, use the surface hardening heat treatment. Cam shaft which is a part of automobile engine is very essential when traveling and significant to fuel injection timing. Stiffness and efficiency are important for automobile sash which have a durability of the engine. High hardness and durability are necessary, because engine output is affected by cam shaft directly. So, high-frequency induction hardening is very important because of increasing the surface strength. The shape of hardening depth, hardened structure, hardness, and fracture characteristics of SM53C composed by carbon steel are also investigated.

High Frequency Induction

Grind-hardening experiments of 40Cr steel were carried out on the external grinder, and the hardness and hardened-depth of the samples were measured and analyzed. Experimental results showed that the external grind-hardening was feasible and could take the place of high-frequency induction hardening. Moreover, dynamic temperature field was simulated and analyzed based on the finite element analysis, and the simulation results were in a good accordance with these of experiment values.
