采用等离子体法在钢和钛合金表面制备了（TiCrC）-（FeCr）复合涂层。这些涂层的成分，结构和摩擦学性能进行了研究，与传统的材料的基础上的Ni-Cr合金。初步表面处理方法的效果，即，研究了喷砂处理和电火花合金化对涂层性能的影响。研究了涂层的微动腐蚀行为。结果表明，在几乎相同的摩擦系数下，基于双钛-铬碳化物的涂层具有比Ni-Cr合金大得多的耐磨性。结果表明，电火花合金化在环境效应和涂层与基体的结合力方面与传统喷砂处理具有竞争力。
The coatings of the (TiCrC)-(FeCr) composite are deposited on steel and titanium alloy by plasma method. The composition, structure, and tribotechnical properties of these coatings are studied in comparison with traditional materials based on the Ni-Cr alloy. The effect of preliminary surface treatment methods, i.e., sandblasting treatment and electrospark alloying, on coating properties is examined. The fretting corrosion of coatings is investigated. It is established that coatings based on double titanium-chromium carbide have considerably greater wear resistance than that of Ni-Cr alloys at almost equal friction coefficients. It is established that electrospark alloying is competitive with traditional sandblasting treatment in environmental effect and coating-to-based adhesion.
