Abstract
Abstract
The surface modification of Ti-6Al-4V substrate was carried out by plasma spraying method (WC-17%Co). The surface morphology and composition of the coating were analyzed. Then, under the air environment, the surface of the plasma sprayed WC was carried out. Friction test of three pairs of friction materials filled with 15% glass fiber + 5% graphite, PTFE filled with 25% glass fiber, and PTFE filled with 60% tin bronze. The treated material improves the friction characteristics of the substrate. However, due to the large thickness and hardness of plasma spraying, it is difficult to use sandpaper to reduce the surface roughness, which will affect the dimensional accuracy of the parts.
