Tribofilm growth, friction and wear behaviour are not well understood for non-ferrous alloys under lubricated contacts in the presence of combination of zinc dialkyl dithiophosphates (ZDDPs) and molybdenum dithiocarbamate (MoDTC) lubricant additives. This study is focused on the growth of tribofilms and tribological properties monitored in situ using an atomic force microscopy (AFM)-based approach. Experiments are performed on the Al matrix and Si phase of Al–Si alloy (ADC12) in the presence of ZDDP and MoDTC at high temperature (110 °C). The addition of MoDTC in ZDDP results in relatively thinner tribofilm over Si phase in comparison to ZDDP alone when sliding is performed simultaneously over the Al matrix and Si phase. The antiwear properties are found to be significantly improved when sliding only on the Al matrix. However, friction reduction is observed in both cases.

在二烷基二硫代磷酸锌（ZDDPs）和二硫代氨基甲酸钼（MoDTC）润滑剂添加剂的组合存在下，非铁合金在润滑接触下的摩擦膜生长，摩擦和磨损行为尚不清楚。这项研究的重点是使用基于原子力显微镜（AFM）的方法对摩擦膜的生长和摩擦性能进行现场监测。在高温（110°C）下，在ZDDP和MoDTC存在下，对Al-Si合金（ADC12）的Al基体和Si相进行了实验。当在Al基体和Si相上同时进行滑动时，与单独使用ZDDP相比，在ZDDP中添加MoDTC会导致Si相上的摩擦膜相对更薄。当仅在Al基体上滑动时，发现抗磨性能得到显着改善。然而，
