A number of substances with different structure have been synthesized and their influence on frictional wear studied. High molecular fatty esters, organo-chloro and organo-sulphur compounds, phosphites, thiophosphites and thiophosphates, and chloroalkyphosphonates have been investigated. The action of chlorine, sulphur, and phosphorus atoms on the anti-wear property of various compounds has been determined. In substances being studied one can observe a direct influence of chlorine, sulphur, and phosphorus on the anti-wear properties of the compounds, namely, on the critical load value and wear at loads above the critical one. Among the anti-wear additives, organo-thiophosphorus and organo-chlorophosphorus compounds have been shown to be of greatest interest. Some chemical aspects of the mechanism of anti-wear additives have been considered. |
