摘要:
通过对基础油、油溶性添加剂和固体润滑添加剂的高温(100～500 ℃)减摩性能和高温 (100～700 ℃) 承载能力的研究发现：当试验温度低于300 ℃时，基础油菜籽油、油溶性添加剂硫化油脂和磷酸酯的摩擦因数比较低，但当试验温度大于300 ℃时，其摩擦因数都非常高；固体润滑剂滑石粉在100～500 ℃时具有较低的摩擦因数，而非层状固体润滑剂硫酸钠具有非常优异的高温承载能力。以菜籽油为基础油研制的热扎超细颗粒钢添加剂具有低温高摩擦和高温低摩擦特性，100 ℃时的摩擦因数为0.31，700 ℃时的摩擦因数为0.20。

Abstract:
The friction-reducing properties and load-carrying ability at high temperature of bases oil, oil-soluble additives and solid lubrication additives were studied. The results showed that the friction coefficients of colza oil, phosphate ester and fatty sulphide are lower, but their friction coefficients become higher at the temperature more than 300 ℃. The friction coefficient of solid lubricant talc is lower from 100 ℃ to 500 ℃. The friendly entironmental lubricants for the manufacturing of ultra fine grain steel by hot rolling possessed the characteristic of higher friction coefficient at low temperature and lower friction coefficient at high temperature. The friction coefficient was 0.31 at 100 ℃ and 0.20 at 700 ℃.
