制备了粉煤灰微珠/环氧树脂复合材料涂层,并利用JM-Ⅴ型磨耗仪对涂层材料进行了磨损试验,研究了粉煤灰微珠含量、微珠粒径以及试验负载和速度对复合涂层耐磨性能的影响.结果表明,随粉煤灰微珠含量的增加,涂层的耐磨性呈先增加后下降的趋势,当填充的微珠质量分数为15％时,复合材料涂层的耐磨性最佳.随微珠粒径的增大,微珠在磨损过程中更加容易破碎,导致复合材料涂层的耐磨性随之下降.对比不同载荷和速度下复合材料涂层的磨损试验结果发现,随负载的增加,复合材料涂层的耐磨性降低;加快试验速度,涂层材料的磨损量也随之变大.
The epoxy resin composite coating filled with fly ash cenospheres was prepared.The wear resistance of the composite coating was measured using JM-Ⅴ abrasion tester.And the effect of cenospheres content,cenospheres particle size,test load and speed on the wear resistance of composite coating was discussed.The results show that with the increase of cenospheres content,the wear resistance of the composites coating increases first and then decreases and it reaches the maximum when the content of cenospheres is 15wt％.With the increase of particle size of cenospheres,the cenospheres are more easily broken in the wear process,which leads to the wear resistance decrease of the composite coating.Compared with the wear test results of the composite coating under different load and speed,it is found that the wear resistance of the composite coating decreases with the increase of the load.Increase the test speed,the wear mass loss of the composite coating will become larger.
