The properties of the MoS/Zr coatings can be significantly affected by the deposition temperature. In this study, the MoS/Zr composite coatings were fabricated on the cemented carbide surface, utilizing the duplex deposition technology at various deposition temperatures. The effects of deposition temperature on the mechanical and friction properties of the MoS/Zr coatings were systematically studied. Results exhibited that as the deposition temperature increased, the adhesion force increased first and then decreased, and the coating thickness and micro-hardness gradually increased. Dry sliding tests against a hardened steel ring showed that the tribological behaviors and wear mechanisms of the MoS/Zr coatings varied with deposition temperature, which were due to the changing mechanical properties of coatings caused by the temperature. The coatings deposited at a temperature of 180 °C and 200 °C possessed preferable comprehensive mechanical and tribological properties.
MoS/Zr涂层的性能会受到沉积温度的显著影响。在本研究中,利用双相沉积技术在不同沉积温度下在硬质合金表面制备了MoS/Zr复合涂层。系统研究了沉积温度对MoS/Zr涂层力学性能和摩擦性能的影响。结果表明,随着沉积温度的升高,附着力先增大后减小,涂层厚度和显微硬度逐渐增加。与硬化钢环的干滑动试验表明,MoS/Zr涂层的摩擦学行为和磨损机制随沉积温度而变化,这是由于温度导致涂层力学性能发生变化所致。在180℃和200℃沉积温度下制备的涂层具有较好的综合力学性能和摩擦学性能。
