Effects of Heating Time of Substrate Post Quenching on Mechanical Properties of TiN Film
Details
A specimen which substrate was quenched after TiN coating was prepared, and the effects of heating time of the post quenching on the mechanical properties of TiN film were investigated. The residual stress and the hardness of TiN film were decreased with increasing the heating time. The adhesive strength and the substrate hardness were increased by the post quenching. With increasing the heating time, they once increased and then became constant from a heating time. In order to improve the adhesive strength and the substrate hardness with minimizing the decreases of the residual stress and TiN hardness, it is necessary to quench the steel substrate in the minimum heating time of which the adhesive strength and the substrate hardness are improved.
