Abstract—

This paper discusses the topical issue of the general compatibility of tribological pairs from the point of view of wear resistance when using various electrospark coatings. For investigation, steel segments were coated with bronze, Mo, and combined Ti + Al + C coatings by electrospark treatment. Coated segments and uncoated control segments were studied in a friction pair with an unhardened C45 steel roller (15HRC) at loads of 300 and 600 N in a lubricant medium. Throughout the test, the coefficient of friction was measured, the wear rate of the tested tribo-pairs was estimated, and the nature of the wear of the friction surfaces after testing was analyzed using optical and scanning electron microscopy (SEM). The results have shown that the most compatible tribo-pairs were steel 45/Bronze and steel 45/Mo, since they have exhibited the best resistance, i.e., the least wear under both loads tested.

润滑介质中由钼，青铜和组合（Ti + Al + C）组成的电火花涂层在45钢上的摩擦磨损

摘要—

本文从使用各种电火花涂层时的耐磨性的角度讨论了摩擦学对的一般相容性这一主题问题。为了进行研究，钢段通过电火花处理涂有青铜，钼和Ti + Al + C组合涂层。使用未硬化的C45钢辊（15HRC）在润滑介质中以300和600 N的载荷在摩擦副中研究了涂层段和未涂层的控制段。在整个测试过程中，测量摩擦系数，评估被测摩擦副的磨损率，并使用光学和扫描电子显微镜（SEM）分析测试后摩擦表面的磨损性质。结果表明，最相容的摩擦副是钢45 /青铜和钢45 / Mo，
