ResumoAbstract Titanium carbonitride [Ti(C,N)] and titanium nitride (TiN) coatings deposited on AISI 440C stainless steel were characterized for resistance to wear and abrasion. The hardness of the coatings as a function of indentation load was determined using a microhardness testing technique. Wear resistance was measured using a reciprocating ball-on-plane test using a hardened 440C stainless steel ball rider. Wear resistance was also measured using ASTM designation G83-83, a crossed-cylinder metal-to-metal test. The abrasion resistance was determined in a loop tester in which abrasive film configured in a continuous loop was abraded against the coatings. It was determined that the Ti(C,N) coating is harder than the TiN coating. The abrasion test demonstrates that the abrasion resistance of Ti(C,N) coating is superior to that of TiN, but the coating versus metal wear resistance is dependent upon the experimental conditions.
