Structure and Properties of Mo Wear Resistant Coating Prepared on TC4 through Glow Plasma Deposition

Abstract:

Mo wear resistant coatings on TC4 alloy were prepared by glow plasma deposition technique. The coatings were deposited at 850-1050°C for 1-5h. Structure, growth kinetics and tribological properties of the coatings were studied. The results revealed that the coatings were mainly consisted of a Mo outer layer and an interdiffusion zone composed of Mo-containing Ti-based solid solution phase just beneath the outer layer. Rising deposition temperature increased coating growth rate. The hardness of the coatings decreased with rising deposition temperature, which caused coating wear resistance decrease. Wear test demonstrated that the Mo coating wear rate was about 1/30 of the TC4 substrate wear rate under dry friction condition at the load of 98N.
