Study on the Friction Characteristics of Plasma Spray Modified Layer on Titanium Alloy in Artificial Sea Water Environment

摘要

In order to study the friction characteristics of the plasma spray modified layer on the surface of titanium alloy, the friction sub-combination consisting of three type enhanced Teflon as the pin sample was carried out in the artificial seawater environment. The results show that the friction coefficient and wear degree of the plasma spray surface treatment specimen are also lower than the TC4 titanium alloy substrate, the surface modification sample and the three enhanced Teflon side friction, the side wear is serious, the surface plasma spray modified titanium alloy needs to reduce its surface roughness before it can be used as a friction sub-type material.
