利用ＣＯ２连续激光器在４５钢表面进行了激光熔敷几种镍基碳化钨合金，对激光熔敷层的显微硬度、组织形貌和腐蚀磨损性能等方面进行了研究，并对激光熔敷层的强化机理作了初步探讨。
Several types of nickel-based tungsten carbide alloys were laser-deposited on the surface of 45 steel by CO2 continuous laser. The microhardness, microstructure and corrosion and wear properties of the laser cladding layer were investigated. The laser cladding layer The strengthening mechanism made a preliminary discussion.
