Abstract
The characteristics of the modified layer of commercially pure BT1-0 titanium (c.p. BT1-0 titanium) after oxygen thermal diffusion saturation (oxidation) and subsequent electrospark alloying (ESA) with a graphite electrode were analyzed. The phase composition of surface layers, their hardness and tribological properties were studied. It was shown that both surface electrospark alloying of titanium with a graphite electrode and combined processing (oxidation followed by ESA) improve its tribological characteristics during friction without lubrication. As a result, the friction coefficient decreases from 0.4–0.5 to 0.15–0.17. At the same time, the wear resistance of titanium increases in 1.2–2.9 times.
期刊介绍：
