In the present study, the effects of TiC coating with or without post heat treatment on fatigue strength and wear characteristics of coated steel specimen were investigated. And also the conspicuous factors of fatigue strength and wear characteristics were studied by detecting residual stresses and hardness. For the specimen, two kinds of steels which were coated with TiC by the chemical vapor deposition (CVD) method, were used. The fatigue property was tested by a bending fatigue test machine.
It was found that quench-tempering heat treatment was very important from the point of view of strength of fatigue and wear, and also found that fatigue strength and wear of TiC coated steels depended on substrate hardness and residual stress of TiC layer and the substrate region adjacent to the interface.
