摘要

为改善镁合金表面的耐腐蚀性能

以铝粉作为激光熔覆材料

在镁表面进行激光熔覆

得到了无气孔、无裂纹且与基体能够良好结合的熔覆层结构。研究了激光工艺参数对该熔覆层的微观组织的影响。

Abstract

In order to improve the corrosion resistance of magnesium alloy surface

taking the Al powder as laser cladding materials

laser cladding Al coating on the magnesium alloy surface was carried out

and the cladding layer with gas-free and crack-free as well as desirable metallurgical bonding with the matrix on the magnesium alloy surface could be generated.Meanwhile

effects of laser parameters on microstructure of the cladding coating were investigated.
