The fabrication of a self-lubricating ceramic composite with MoS as the solid lubricant is extremely difficult given the high temperature sensitivity of MoS. In this study, a hydrothermal method was utilized for the in situ synthesis of nanosized-MoS in AlO ceramic to fabricate an AlO-MoS self-lubricating composite. The composite exhibited excellent self-lubricating properties with low friction coefficient and wear rate in a high-vacuum environment because of the efficient formation of self-lubricating films from the finely structured MoS in the AlO matrix. The results of this study establish a new approach to the fabrication of self-lubricating ceramic composites with temperature-sensitive solid lubricants.
由于 MoS 的高温敏感性,用 MoS 作为固体润滑剂来制造自润滑陶瓷复合材料极其困难。在这项研究中,采用水热法在 AlO 陶瓷中原位合成纳米 MoS,制备了 AlO-MoS 自润滑复合材料。由于 AlO 基体中细结构的 MoS 有效地形成了自润滑膜,该复合材料在高真空环境下表现出优异的自润滑性能,摩擦系数和磨损率都很低。本研究为用温度敏感的固体润滑剂制造自润滑陶瓷复合材料提供了一种新方法。
