Research of Low Friction Coefficient Ceramic Coating Pairs Under Water-lubrication

主要针对水润滑条件下低摩擦系数摩擦副——包括主动副和从动配副的材料和性能进行设计研究。研究了3种复合陶瓷涂层制备的主动副与3种摩擦性能良好的整体材料组配进行摩擦性能试验。通过销-盘磨损试验,测定各组摩擦副的摩擦系数和磨损量;利用SEM等测试技术,观察和分析了磨痕的形貌,重点讨论了陶瓷涂层材料的组分设计及其显微结构,涂层与配副材料在水润滑条件下的摩擦学性能。结果显示:在水润滑下所设计的3种陶瓷涂层所组成的摩擦副具有较低的摩擦系数,能够耐海水侵蚀以及抗微生物附着,是一种海水中使用的理想摩擦组件。

According to the low friction coefficient pairs under water-lubrication, which contain active pair and passive pair, their materials and performance were designed and studied in this paper. Friction experiments were on three ceramic composite coatings of active pairs and three excellent friction material groups. Through a pin-on-disc configuration, friction coefficient and wear weight were tested. The morphology of the wear trace was observed by SEM. The discussion was on the constituent design and the microstructure of ceramic composite coatings, the tribological properties of the coatings and passive pair materials on the condition of water-lubrication. The results indicated that friction pairs of three ceramic composite coatings designed under water-lubrication has lower friction coefficient. This can endure better of the corrosion of the seawater and the adhesion of the microorganism, so it was an ideal friction module when it was used in the seawater.
