摘　　要：搅拌头是搅拌摩擦焊工艺的关键。在探讨铜合金搅拌摩擦焊工艺的基础上,对铜合金搅拌摩擦焊过程中硬质合金搅拌头的磨损机理进行了比较系统的试验研究。通过对试验研究结果的分析,初步将搅拌头的磨损归结为粘结磨损、氧化磨损、扩散磨损、脆性剥落和脆断。Tool is a key factor in the friction stir welding process. Under friction stir welding process for copper alloys, the tool＇s wear mechanism in friction stir welded copper alloys was theoretically investigated. Based on the experiments, the mechanism can be summed up as follows： adhesion wear, oxidative wear, diffusion wear, micro-breakout and brittle fracture.
