Process for laser cladding of nickel-based tungsten carbide on copper alloy core glass mold

The invention relates to a process for laser cladding of nickel-based tungsten carbide for a copper alloy core glass mold. The process comprises the following steps that A, machining turning is carried out on a copper alloy core to obtain a workpiece before cladding; B, laser cladding pre-treatment is carried out, specifically, oil stains and dust on the surface of the core are cleaned; C, a track program is programmed; D, laser cladding is carried out, specifically, technological parameters are set, laser cladding is carried out along a program track, and adopted nickel-based tungsten carbide alloy powder comprises the following components of, 1.28% of B, 2.38% of C, 4.37% of Co, 7.63% of Cr, 2.04% of Fe, 2.34% of Si, 31.06% of W and the balance Ni. 本发明涉及一种铜合金芯子玻璃模具激光熔覆镍基碳化钨工艺；包括以下步骤：A）对铜合金芯子进行机加工车削，获得熔覆前工件；B）激光熔覆前道处理：清洁芯子表面油污及粉尘；C）编程轨迹程序；D）激光熔覆：设定好工艺参数，沿着程序轨迹进行激光熔覆。所采用的镍基碳化钨合金粉成分为B:1.28%，C:2.38%，Co:4.37%，Cr:7.63%，Fe:2.04%，Si:2.34%，W:31.06%，其余均为Ni。
