Protection Properties of TiN Coating Prepared by Arc Ion Plating and Magnetron Sputtering on TC11 Titanium Alloy Original Research Article

TiN coating was deposited on TC11 titanium alloy by arc ion plating technique and reactive direct current (D.C.) magnetron sputtering technique. The phases of TiN coating were determined by XRD technique. The surface morphology and hardness of TC11 alloy and TiN coating were analyzed by SEM and Micro-hardness Detector measurements, respectively. The tribological behaviors of reciprocating sliding for two TiN coatings which prepared by different PVD technologies (magnetron sputtering and ion plating) were studied on UMT wear tester. The results showed that wear properties of TC11 alloy were considerably improved by two TiN coatings.
