蛇纹石对不同粗糙度45^#钢表面的减摩行为
Friction-Reducing Performance of Serpentine on 45# Carbon Steel Surfaces with Different Roughnesses
摘要
Abstract
The 45# carbon steel pair surfaces with three different roughnesses were prepared. The friction-reducing performance of serpentine on the three surfaces was investigated by an MMW-1A universal fi＇iction and wear tester. The worn surfaces were analyzed by three-dimensional video microscopy, scanning electron microscopy and energy dispersive spectroscopy, respectively. The results show that the friction-reducing effect of serpentine is more remarkable to smooth surface. When the surface roughness Ra was 0.742 lam, the worn surface was repaired effectively, the friction coefficient was decreased, the wear mass loss was no more than 1.3 rag, and the surface roughness was reduced by 72.1%. Nevertheless, the friction and wear behavior obeyed the wear feature of normal metallic materials when the Ra was 1.424 and 3.706um. The self-repairing film could smooth the worn surface, and there was a dy- namical equilibrium between wear and the formation of self-repairing film.关键词
