In the paper, experimental and numerical results of the wear of a molybdenum disulfide coated on a titanium alloy disk are reported. The coating is in contact with a sapphire ball. The experiments are conducted for ambient temperatures varying from 20 to 350 \(^\circ \)C. The results indicate that the wear profile becomes increasingly pronounced at the growth of the temperature up to 350 \(^\circ \)C. A numerical model is proposed to describe the results of the experiment. The central assumption is the thermal steady state forming in the interface area. The resulting stress field serves as input for the simulation of wear. A good agreement can be observed between the experimental findings and the FE calculations.

在本文中，报告了钛合金盘上涂覆的二硫化钼的磨损的实验和数值结果。涂层与蓝宝石球接触。实验在 20 至 350°C 的环境温度下进行。结果表明，当温度升至 350°C 时，磨损轮廓变得越来越明显。提出数值模型来描述实验结果。中心假设是在界面区域形成热稳态。产生的应力场作为磨损模拟的输入。实验结果与有限元计算之间可以观察到良好的一致性。
