Aiming to study the influence of temperature on the wear mechanism, we fabricated (Cr, V)N coating by cathodic arc ion-plated and conducted tribological experiments at 500–900 °C. The results indicated that there were two tribological behaviors, depending on the temperature. Below 600 °C, the (Cr, V)N coatings exhibited a high friction coefficient, but generated a mild wear because of the slight oxidation. Above 700 °C, the increased oxidation degree reduced adhesion of asperity contacts. However, the wear rate enhanced significantly with the temperature increasing from 700 to 900 °C due to the fast oxidation accompanied by the decrease in both hardness and adhesion strength.

为了研究温度对磨损机理的影响，我们通过阴极电弧离子镀制备了（Cr，V）N涂层，并在500–900°C下进行了摩擦学实验。结果表明，取决于温度，存在两种摩擦学行为。低于600°C，（Cr，V）N涂层表现出较高的摩擦系数，但由于轻微的氧化而产生了轻微的磨损。高于700°C，增加的氧化度会降低粗糙接触的附着力。然而，由于快速氧化伴随着硬度和粘附强度的降低，磨损率随着温度从700升高至900°C而显着提高。
