沉积温度对TC4钛合金表面辉光离子渗Mo层组织和耐磨性能的影响
Effects of Deposition Temperature on Microstructure and Wear Resistance of Mo Coating Prepared by Glow Plasma Deposition on TC4 Titanium Alloy
摘要
Abstract
Mo coatings on TC4 alloy were prepared by glow plasma deposition technique at 850-1050℃ for 1-5 hours.Structure,wear rate and mechanics of the coatings were studied by using XRD,SEM,EDS,microhardness device and friction wear testing machine.The results reveal that the coatings are mainly consisted of Mo layer and an interdiffusion zone composed of Mo-Ti solid solution.The coating average grain size increases with rising deposition temperature,which causes the decrease of Mo coating hardness and wear resistance.Wear tests demonstrate that the wear rate of the Mo coating prepared at 950℃ for 5h is about 1/45 of the TC4 substrate wear rate under simple sliding and dry friction condition with a load of 98N.关键词
