Abstract
This paper adopts wet method to prepare serpentine particles on the planetary ball mill, executes lipophilic degree tests and friction and wear tests of these particles. The results showed that: 1) as the modification agent, the optimum dosage of oleic acid is when the volume ratio of oleic acid and serpentine particles is 2, and the optimum time of milling (modification) is 24h. 2) 4012 maritime lubricating oil with serpentine particles has obvious anti-wear and friction effect, and the optimum dosage range of serpentine particles is 0.9%-1.0%. According to the outcomes of metallurgical microscope observation and electron microprobe analysis, a conclusion can be drawn: during the process of friction and wear, serpentine particles brought on physical or chemical reactions with the surface of test samples, create a layer of protective film, thus this kind of lubricating oil has filling function to the furrow of friction pair surface, so as to decrease the surface roughness, decrease the degree of friction and wear.
