为了改善纯铜的耐磨性,通过FSP的打孔填粉的方式在纯铜板材中植入氧化镧,使用FSP的方式,使其分布均匀,并对加工后的样品进行了硬度及耐磨性测试.结果表明,添加的氧化镧粉末在经过FSP后能均匀扩散至样品表面,其硬度值高于母材及对照组,平均硬度相较于母材提升了约24.2%,同时Cu-La2O3表层具有更好的耐磨性,其在常温条件下的磨损量仅为母材的17.6%.
Performance Analysis of Cu-La2O3 Surface Layer Prepared by FSP
In order to improve the wear resistance of pure copper,lanthanum oxide was implanted into the pure copper plate by the way of punching and filling powder of FSP.The distribution of lantha-num oxide was uniform by using FSP.The hardness and wear resistance of the processed samples were tested.The results showed that the added lanthanum oxide powder could be evenly diffused to the sur-face of the samples after FSP.Its hardness value was higher than that of the base metal and the control group,and the average hardness was increased by about 24.2%compared with the base metal.At the same time,the Cu-La2O3 surface has better wear resistance,and its wear loss at room temperature is only that of the base metal 17.6%.
