摘    要:青铜具有极好的耐海水腐蚀性和耐磨损性能,在舰艇、船舶中大量存在青铜零件,但对这些零件进行修复非常困难。由于青铜对激光的强烈反射及其优良的热传导性,给激光熔覆修复青铜零件带来了很大的困难。通过激光熔覆修复实验,优化了激光熔覆修复工艺参数。在对激光熔覆修复过程进行最优控制的条件下,获得了界面结合良好、耐腐蚀性和耐磨损性均符合要求的激光熔覆修复试样。在此基础上,实现了对实际舰船青铜零件的激光熔覆修复。

关 键 词:激光熔覆修复  舰艇和船舶  青铜零件

Abstract:The bronze has excellent corrosion resistance and abrasion resistance. There are a large number of bronze parts in ships and warships. But the repair of these parts is very difficult. Due to the strong reflection to the laser and the excellent thermal conductivity of bronze ,it also brings great difficulties in laser cladding repair. The experimental parameters of laser cladding repair were optimized by laser cladding repair experiment. Under the condition of the optimal control of laser cladding repair process,the laser cladding repair samples with good interface,corrosion resistance and wear resistance are obtained. On the basis of the experiment ,the laser cladding repair of the bronze parts of the actual ship is realized.
Keywords:laser cladding repair  warships and ships  bronze parts
