The abrasive wear resistance of plasma-sprayed oxide ceramic (Al 2 O 3 and Cr 2 O 3 ) and clad cermet ((Ti–Cr–C)–30% Ni and (TiC)–30% Ni) coatings was studied. The wear characteristics of the coatings such as wear rates, friction forces, friction coefficients, and wear groove depth determined with two methods were compared. The wear test methods included simulation of the friction process using loose abrasive particles and reciprocal ball-on-disk friction using a diamond indenter. The plasma-sprayed TiC-based coatings showed the lowest wear rate and can be applied to protect equipment parts subjected to intensive abrasive wear. The wear loss of the (Ti–Cr–C)–30% Ni and (TiC)–30% Ni coatings determined by friction against loose abrasive particles was 10–17 μm, while the wear loss of the oxide ceramic coatings was 20–42 μm, being 2–2.5 times higher on average.

强磨损条件下等离子喷涂涂层的耐磨性

研究了等离子喷涂氧化物陶瓷（Al 2 O 3 和 Cr 2 O 3 ）和复合金属陶瓷（(Ti–Cr–C)–30% Ni 和 (TiC)–30% Ni）涂层的耐磨性。比较了两种方法测定的涂层的磨损特性，如磨损率、摩擦力、摩擦系数和磨损槽深度。磨损测试方法包括使用松散磨粒模拟摩擦过程和使用金刚石压头进行球盘相互摩擦。等离子喷涂 TiC 基涂层的磨损率最低，可用于保护遭受严重磨损的设备部件。(Ti–Cr–C)–30% Ni 和 (TiC)–30% Ni 涂层的磨损损失通过与松散磨粒的摩擦测定为 10–17 μm，而氧化物陶瓷涂层的磨损损失为 20– 42 μm，为 2–2。
