Effect of Surface Modification on Tribological Properties of VT22 and Ti-5553 Titanium Alloys
Tribological properties of VT22 and Ti-5553 titanium alloys are improved due to the chemical-thermal treatment of their surfaces and the application of a wear-resistant titanium nitride coating. The tribological properties were compared for samples without additional surface treatment, with surface modification by nitriding, with the titanium nitride coating, as well as with a two-stage treatment of sample surfaces, including primary nitriding of the surface followed by the application of a titanium nitride coating on it. It was found that low wear resistance is observed in titanium samples without coatings, while the wear resistance of samples with a nitrided surface layer increases for both types of tested alloys. Minimal wear occurs for the samples with two-stage formation of a titanium nitride coating while on samples without an intermediate nitrided sublayer, when tested with a ceramic ball, delamination of the coating is observed; the formation of the sublayer prevents this type of destruction.
期刊介绍：
Journal of Friction and Wear is intended to bring together researchers and practitioners working in tribology. It provides novel information on science, practice, and technology of lubrication, wear prevention, and friction control. Papers cover tribological problems of physics, chemistry, materials science, and mechanical engineering, discussing issues from a fundamental or technological point of view.
