摘要: 通过醇-水溶液加热方法,制备出Y-TZP包裹MoS2复合粉末,通过热压烧结,制备具有特殊显微结构、力学性能优良的Y-TZP/MoS2复合材料,考察了室温下复合材料与ZrO2配副时的摩擦学性能.结果表明:当材料中含有44wt%MoS2时,其摩擦系数为0.25、磨损率为1.05×10-6mm3/m·N.

Abstract: MoS2 powders coated with Y-TZP were prepared by heating alcohol-water solution of ZrOCl2·8H2O and Y(NO3)3·6H2O with particles of MoS2. Y-TZP/MoS2 composites with special microstructure and good mechanical properties were fabricated by hot pressing sintering. The tribological properties of Y-TZP/MoS2 composites sliding against ZrO2 at room temperature were investigated. Results show that the friction coefficient of the composite with 44wt% MoS2 added is as low as 0.25, and the wear rate of the composite is 1.05×10-6mm3/m·N
