研究了二叔十二烷基二硫醚作为添加剂对52100轴承钢初生表面MAC油分解的影响。去除表面污染层后，产生活性中心，MAC油在活性中心上发生摩擦化学分解。添加剂延长了分解诱导期。氢和气态烃作为摩擦化学反应产物解吸。氢和气态烃的解吸速率与滑动速度成正比，与载荷的立方根成线性关系。XPS分析表明，添加剂与初生表面发生了摩擦化学反应，导致硫化铁的生成和初生表面活性的降低。结果，MAC油的分解相应地减少。
Effect of di-tert-dodecyl disulfide as an additive on decomposition of MAC oil on the nascent surface of bearing steel 52100 was investigated. After the removal of surface contamination layer, active sites were generated, on which tribochemical decomposition of MAC oil occurred. The additive prolonged the induction period of the decomposition. Hydrogen and gaseous hydrocarbons desorbed as tribochemical reaction products. Desorption rate of hydrogen and gaseous hydrocarbons increased proportionally with sliding velocity and linearly with the cube root of load. XPS analysis revealed tribochemical reaction between additive and nascent surface occurred, which induced formation of iron sulfide and decrease of activity of nascent surface. As a result, decomposition of MAC oil decreased correspondingly.
