摘要

The tribological behavior of specimens coated by two layers, titanium carbonitride film as the top layer and titanium film as the underlayer, is studied in this work. The coating layers were deposited using the cathodic-arc ion plating process (CA) technique. Experiments were carried out on a wear test machine using a thrust-washer adapter to simulate the surface contacts between the steel ring (the upper specimen) and the titanium carbonitride coated washer (the bottom specimen). We address the influence of the thickness of the two coating layers on tribological behavior, the wear mechanism, specimen hardness, coating morphology, and adhesive strength. Higher measured values of electrical voltage are always obtained in the specimens with lower adhesion strength. A thin titanium carbonitride film with a thick titanium underlayer decreases the adhesion strength, resulting in a higher wear rate. The effect of surface morphology on specimen wear rate is dependent upon the sliding speed and the coating thickness. When the specimen's sliding speed is raised, both the wear rates and the friction coefficients decrease significantly.
