摘要 在制备硅灰石填充尼龙(PA)1010复合材料的基础上,测试了复合材料的摩擦磨损性能,通过扫描电子显微镜(SEM)观察摩擦面的形貌,探讨了摩擦磨损机理,分析了复合材料的力学性能和热性能对摩擦磨损性能的影响。结果表明,硅灰石的加入大幅降低了PA1010与钢材间的摩擦系数和磨损量。当硅灰石质量分数为70%时,复合材料的摩擦系数和磨损量仅为纯PA1010的54.7%和11.4%,PA1010的耐磨性得到显著改善。硅灰石的加入减轻了PA1010的粘着磨损和疲劳磨损,当硅灰石质量分数为70%时只有轻微的犁沟现象。随着热变形温度和拉伸弹性模量的提高,体积磨损量降低,摩擦系数逐渐减小。 Nylon 1010/wollastonite composites were prepared by melt blending. The tribological properties were investigated through the reciprocating sliding wear test,the friction surface topography and the abrasion mechanism was analyzed by SEM,the relationships of tribological properties with elastic modulus and heat deflection temperature were discussed. The results show that the friction coefficient and wear loss of nylon 1010/wollastonite composites decreases dramatically with the increasing of the wollastonite content. The friction coefficient and wear loss of nylon1010 with wollastonite mass fraction of 70% are about 54.7% and 11.4% of the pure nylon 1010 respectively. The resistance to wear of nylon1010 gets much better. The adhesive wear and fatigue wear have reduced with the addition of wollastonite,there is only furrow phenomenon on the wearing surface when wollastonite content is 70wt%. The friction coefficient and wear loss of nylon 1010/wollastonite composites decreases with the raise of tensile elastic modulus and heat deflection temperature.
