Experiments are carried out under a high-load, low-speed condition, where wear takes place predominatly. Results show that the tempering prolongs the film life more than twice. This is caused by increased fracture toughness of the substrate and improved adherence at the coating-substrate interface by formation of a high-titanium layer, both suppressing wear of the TiN layer by scratching.
