摘    要:为了探索涡轮叶尖端部型腔涂层的制备工艺,以堆焊用镍基合金焊条加工成的粉末为原材料,分别采用激光熔覆及氩弧堆焊技术,在铸造镍基合金试样表面上制备涂层.结果表明:激光熔覆涂层在成型性上优于堆焊涂层,激光熔覆涂层的组织细小致密,硬度高于堆焊涂层的硬度;在涡轮叶尖上进行激光熔覆涂层工艺探索也获得成功.

关 键 词:涡轮叶尖  激光熔覆  镍基合金  涂层

Abstract:In order to research a model structure coating on turbine blade tip,a laser cladding coating and an argon-arc surfacing welding coating were deposited on surface of casting Ni-base alloy samples.A kind of powder made of Ni-base alloy surfacing welding rod was used in laser cladding technology.The experimental results indicate that the material forming of the laser cladding coating is better than that of the argon-arc surfacing welding coating.The microstructure of laser cladding coating is fine and dense.Th...
Keywords:turbine blade tip  laser cladding  Ni-base alloy  coating
