A multilayer film, composed by ZrN-Ag (20 nm) and Mo-S-N (10 nm) layers, combining the intrinsic lubricant characteristics of each layer was deposited using DC magnetron sputtering system, to promote lubrication in a wide-range of temperatures. The results showed that the ZrN-Ag/Mo-S-N multilayer film exhibited a sharp interface between the different layers. A face-centered cubic (fcc) dual-phases of ZrN and Ag co-existed in the ZrN-Ag layers, whilst the Mo-S-N layers displayed a mixture of hexagonal close-packed MoS2 (hcp-MoS2) nano-particles and an amorphous phase. The multilayer film exhibited excellent room temperature (RT) triblogical behavior, as compared to the individual monolayer film, due to the combination of a relative high hardness with the low friction properties of both layers. The reorientation of MoS2 parallel to the sliding direction also contributed to the enhanced anti-frictional performance at RT. At 400 °C, the reorientation of MoS2 as well as the formation of MoO3 phase were responsible for the lubrication, whilst the hard t-ZrO2 phase promoted abrasion and, consequently, led to increasing wear rate. At 600 °C, the Ag2MoO4 double-metal oxide was the responsible for the low friction and wear-resistance; furthermore, the observed transformation from t-ZrO2 to m-ZrO2, could also have contributed to the better tribological performance.

纳米多层ZrN-Ag/Mo-SN薄膜设计,在宽温度范围内具有稳定的减摩性能



使用直流磁控溅射系统沉积由 ZrN-Ag (20 nm) 和 Mo-SN (10 nm) 层组成的多层膜,结合各层的固有润滑特性,以促进在宽温度范围内的润滑。结果表明,ZrN-Ag/Mo-SN多层薄膜在不同层之间呈现出清晰的界面。 ZrN 和 Ag 的面心立方 (fcc) 双相共存于 ZrN-Ag 层中,而 Mo-SN 层则呈现六方密堆积 MoS 2 (hcp-MoS 2 ) 纳米颗粒的混合物和非晶相。与单个单层薄膜相比,多层薄膜表现出优异的室温 (RT) 摩擦学行为,因为两层都具有相对高的硬度和低摩擦特性。 MoS 2平行于滑动方向的重新取向也有助于增强室温下的减摩性能。在 400 °C 时,MoS 2的重新取向以及 MoO 3相的形成负责润滑,而硬质 t-ZrO 2相则促进磨损,从而导致磨损率增加。在600℃时,Ag 2 MoO 4双金属氧化物具有低摩擦和耐磨性;此外,观察到的从t-ZrO 2到m-ZrO 2的转变也可能有助于更好的摩擦学性能。
