摘要：

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.
