摘　　要：利用振荡聚焦光束和自动送粉技术 ,获得单道宽 12mm以上、组织致密无缺陷的镍基合金激光熔覆层 ,并对其硬度分布。With techniques of vibrating focusing beam and automatic powder feeding, a faultless laser-cladding layer of Ni based alloy with single-track width of 12 mm and thickness of 0.9 mm was obtained. In experiment, NiO2 was used as Ni-based alloy powder, and 45 steel was used as base material. Its hardness distribution, metallurgical structure and compositions were investigated and analyzed.

关 键 词：宽带激光熔覆 振荡聚焦光束 自动送粉 镍基合金
