【摘要】 利用MRH-3环块摩擦试验机实验考察了4种商用含磷润滑添加剂在钢-镁摩擦副间的摩擦学性能。研究表明:考察的磷酸酯能显著提高基础油的承载能力,且比基础油具有更优良的减摩效果;但在轻载下导致的镁合金体积磨损量均较基础油大。探讨了磷酸酯添加剂摩擦学特性与其反应活性的相关性。更多还原

【Abstract】 The tribological properties of P-containing lubrication additives in the sliding of steel against magnesium alloy were investigated by MRH-3 tester. It was found that phosphates can evidently increase the load-carrying ability of base stock,and reduce the friction coefficient of base stock. However,all P-containing lubrication additives produce larger wear volume than base stock under lower load condition. The relationship between tribological properties of the additives and their chemical reactivity with magnesium was also found.更多还原
