TC2、TC6表面喷涂WC-17Co与电镀铬耐磨性能对比

Wear Resistant Comparison of Spraying WC-17Co Coating and Chromium Plating on the Surface of TC2 and TC6

TC2、TC6钛合金是航空领域中常用的选材,为了增加钛合金配合表面的耐磨性能,对钛合金表面进行超音速火焰喷涂碳化钨,研究对比TC2、TC6钛合金表面喷涂WC-17Co和镀硬铬的摩擦性能。结果表明:表面喷涂WC-17Co可获得致密表面,孔隙率小于0.5%,同时耐磨性能显著提高。

TC2 and TC6 titanium alloys are commonly used in the aerospace field.In order to increase the wear resistance of titanium alloy mating surface,the surface of titanium alloy was sprayed with supersonic flame tungsten carbide,and the friction properties of TC2 and TC6 titanium alloy by spraying WC-17Co and hard chromium plating were compared.The results showed that a compact surface can be obtained by spraying WC-17Co,the porosity was less than 0.5%,and the wear resistance was significantly improved.
