Zusammenfassung:A lubricant composition comprising an oil of lubricating viscosity and 0.01 to 5 percent by weight of a substantially sulfur-free alkyl phosphate amine salt, where at least 30 mole percent of the phosphorus atoms are in an alkyl pyrophosphate salt structure, exhibits good antiwear performance. In the phosphate amine salt, at least 80 mole percent of the alkyl groups are typically secondary alkyl groups of 3 to 12 carbon atoms. 本发明涉及润滑剂组合物,其包含具有润滑粘度的油和0.01-5重量%的基本上不含硫的烷基磷酸酯胺盐,其中至少30摩尔%的磷原子是在烷基焦磷酸酯盐结构中,显示优良的抗磨性能。在磷酸酯胺盐中,至少80摩尔%的烷基典型地是具有3-12个碳原子的仲烷基。
