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％.
