为了研究温度对磨损机理的影响，采用阴极电弧离子镀方法制备了（Cr，V）N涂层，并在500-900 °C下进行了摩擦学试验。结果表明，随着温度的升高，摩擦学行为表现为两种类型。在600 °C以下，（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轻微的磨损。在700 °C以上，增加的氧化程度降低了粗糙接触的粘附性。当温度从700 °C升高到900 °C时，由于氧化速度加快，硬度和结合强度下降，磨损率显著增加。
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.
