摘要/Abstract

摘要： 考察了（Ca，Mg）－Sialon陶瓷与钢对摩时在一元醇润滑下的摩擦及磨损性能．结果表明，一元酵对（Ca，Mg）－Sialon具有良好的润滑效果，与干摩擦时相比，磨损量降低了1～2个数量级，摩擦系数从干摩擦的0．81降低至0．09；摩擦副的摩擦系数随着碳链的增长呈现复杂变化，而Sialon的磨损体积则随碳链的增长而递减．红外光谱（FTIR）及凝胶渗透色谱（GPC）分析表明，一元醇润滑下陶瓷表面生成了Si－O－R基聚合物，这层聚合物膜具有良好的减摩抗磨效果．根据试验结果并参照文献，提出了一元醇的润滑机制．

Abstract: The friction and wear behaviors of (Ca, Mg)-Sialon/GCr15 steel couple lubricated by alcohols such as 1-propanol 1-butanol 1-hexanol 1-octanol and 1-decanol were investigated by SRV friction and wear tester
in a ball-on-disk configuration. It was found that, as compared with dry sliding, all the alcohols not only reduced the friction coefficient of
(Ca, Mg)-Sialon sliding against GCr15 steel significantly but also reduced the wear volume of (Ca, Mg)-Sialon considerably (1-2 order).
Results of Fourier transform infrared spectroscopic (FT-IR) and GPC analyses showed that tribochemical reaction between (Ca, Mg)-Sialon
and alcohols was involved in the friction process. The formation of Si-O-Si, Si-C and Si-O-C based friction-polymer on the rubbed surfaces
is attributed to the excellent friction and wear reduction of alcohols. The lubrication mechanism of alcohols was propounded according to the
experimental results and the references.
