摘要

This study proposed a method using the friction stir surface processing (FSSP) technology to modifythe surface layer of copper alloy and hence improve its corrosion resistance. H62 copper alloy wasused for the purpose. The modification parameters in the FSSP were set as follows: rotation speed,1200 rpm; traversing speed, 150 mm/min; and depth 0.15 mm. The findings revealed that the surfaceof the modified sample with a depth of 0.15 mm had a higher degree of metallographic refinement andbetter hardness and corrosion resistance. The modified samples after one, two and three passes werecompared. It was found that the metallographic structure of the two-pass modified samples was fineand uniform, and the hardness and corrosion resistance were the best, followed by the one-passmodification, with the three-pass modification being the worst.
