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.

用石墨电极进行电火花合金化氧化后对钛进行表面改性

分析了商用纯 BT1-0 钛（c.p. BT1-0 钛）经过氧气热扩散饱和（氧化）和随后与石墨电极进行电火花合金化（ESA）后改性层的特性。研究了表面层的相组成、硬度和摩擦学特性。结果表明，用石墨电极对钛进行表面电火花合金化和组合加工（先氧化后ESA）都能改善钛在无润滑摩擦时的摩擦学特性。因此，摩擦系数从 0.4-0.5 降至 0.15-0.17。同时，钛的耐磨性提高了 1.2-2.9 倍。
