In this work, TiC coating was fabricated by atmospheric plasma spray (APS) technique and its tribological performances sliding against stainless steel, Si 3 N 4 and WC-Co were evaluated using ball-on-disk tests under 50 N load. The results indicated that the TiC coating exhibited diverse tribological behaviors. The TiC/Si 3 N 4 tribopair showed the lowest friction coefficient with a significant fluctuation. The TiC/steel tribopair exhibited the lowest coating wear rate, while the TiC/WC-Co tribopair had the highest coating wear rate among the three tribopairs. The tribological mechanisms were tentatively explained based on the observation of worn surfaces. This work might provide some clues for the applications of TiC coatings.

等离子喷涂TiC涂层滑动对不同对应件的磨损行为比较研究

在这项工作中，采用大气等离子喷涂 (APS) 技术制造 TiC 涂层，并在 50 N 载荷下使用球盘试验评估其与不锈钢、Si 3 N 4 和 WC-Co 滑动的摩擦学性能。结果表明，TiC涂层表现出不同的摩擦学行为。TiC/Si 3 N 4 摩擦副表现出最低的摩擦系数，并具有显着的波动。TiC/钢摩擦对的涂层磨损率最低，而 TiC/WC-Co 摩擦对的涂层磨损率在三种摩擦对中最高。基于对磨损表面的观察，初步解释了摩擦学机制。这项工作可能为 TiC 涂层的应用提供一些线索。
