| 摘 要： | 采用中频磁控溅射和多弧离子镀相结合的工艺在硬质合金YT15刀片表面制备了MoS2-Zr复合涂层,考察了其形貌、结构和摩擦磨损性能,分析了复合涂层的减摩机理.结果表明,与纯MoS2涂层相比,MoS2-Zr复合涂层的硬度和与基体之间的结合力获得显著提高(纯MoS2涂层的硬度约为4.0 GPa,与基体之间的结合力约为49 N;MdS2-Zr复合涂层的硬度约为10.7 GPa,与基体之间的结合力约为55 N).与45#钢的对摩试验结果表明,MoS2-Zr复合涂层的摩擦系数和磨损率均小于纯MoS2涂层的摩擦系数和磨损率.MoS2-Zr复合涂层与对摩材料之间所形成的转移润滑膜是影响摩擦过程中的摩擦系数的关键因素之一.由于摩擦副间转移膜的存在,涂层和对摩材料的摩擦转变为涂层和转移膜之间的摩擦,从而降低了摩擦系数,提高了材料的耐磨损性能.

| Abstract: | MoS2-Zr composite coatings were deposited on YT15 cemented carbide substrates by a hybrid method,which is called medium-frequency magnetron sputtering coupled with arc ion plating techniques.The thickness,micro-hardness,adhesion strength between substrate-coating of the composite coatings were studied.The morphology,composition and structure of the MoS2-Zr coatings were investigated by SEM,EDX and XRD,and the friction and wear properties were determined on a pin-on-disc tribo-tester.The results indicated th... |
