利用微摩擦磨损试验机评价果胶作为水基润滑添加剂的摩擦学性能，采用扫描电子显微镜分析磨痕表面形貌，并采用能量色散光谱仪分析摩擦磨损机制。同时还考察工业用水中存在的阴离子对含果胶水基润滑液摩擦学性能的影响。结果表明：在去离子水中加入少量的果胶就可显著改善水的摩擦学性能，并且随着果胶添加量的增大，减摩性能得到进一步提高，这主要是由于果胶在表面吸附形成的润滑膜起到良好的减摩效果；不同阴离子对果胶的摩擦学性能具有不同的影响，其影响的实质是盐析作用和吸附作用。

The tribologial performance of pectin polysaccharide as additive of water-based lubricant was studied by using micro friction and wear tester.The lubricating mechanisms of aqueous solution of pectin were analyzed by SEM and EDS. And the effect of the anions existed in the industrial water on the tribologial performance of water-based lubricant of pectin was investigated.The results pectin polysaccharide shows low friction when used as an additive in water.With the increase of the additive amount of pectin polysaccharide in water,the friction reducing performance is improved.This is mainly due to formed lubrication film by adsorption of the pectin on the surface.The types and concentration of anions shows different impacts on the friction reduction performance of the water-based lubricant of pectin,it is because of the salting-out effect and the adsorption of anions on the steel surfaces.
