摘要: Previous studies have shown that many anti-wear additives a tendency to aggravate micropitting damage in hard steels subjected rolling sliding contact at low lambda values. This is apparently because suppress the gradual smoothing of rough surfaces takes place when pure base stock used under mild conditions. However, practice, it common combine and friction modifier formulated oils, combination leads reduced boundary friction. In work described this article, we added agent, molybdenum bis-diethylhexyl dithio-carbamate (MoDTC), an oil containing additive, secondary zinc dialkyl-dithio-phosphate (ZDDP) mineral base-stock. We examined behavior using disc tester. The with both MoDTC ZDDP showed initial gradually disappeared continued running, whereas alone led continuing severe damage. Analysis counter-discs ...
