摘　　要：激光熔覆修复是近年来迅速发展的一项有许多突出优点的零件修复技术,文章对该技术进行了基础性的试验研究,模拟实际零件的修复情况,通过在基体材料上加工一个"U"形缺口并用激光熔覆技术进行修复。把激光熔覆修复件制作成力学性能试件,获得了相关的试验数据,并对试验结果进行了分析,为激光熔覆修复技术的实际工程应用提供了理论依据。Laser cladding repairing is a new developing technology of parts repairing. It has many advantages. The basic experimental researches on the laser cladding repairing technology have been carried out. Simulating the actual parts repairing, a ＂U＂ shape of groove has been machined on a substrate of 2Cr12 and repaired by laser cladding. The testing pieces of mechanics properties have been made with the laser cladding part. The experimental results have been obtained and the analyses on the experimental results have been carried out. A theory reliance of laser cladding repairing on actual parts has been provided.
