摘　　要：采用高频感应堆焊工艺制备碳化钨颗粒增强高铬铸铁基高频感应堆焊层,并对其微观组织和耐磨性能进行研究。结果表明,与普通高铬铸铁基堆焊层相比,采用高频感应堆焊工艺制备的碳化钨颗粒增强高铬铸铁基高频感应堆焊层具有更高的硬度和更好的耐磨性能。The tungsten carbide reinforced high chromium cast iron high frequency surfacing was prepared by high fi＇equency induction cladding technology, and the microstructure and wear resistance of the surfacing layer were studied. The results show that both the hardness and wear resistance of the tungsten carbide reinforced high chromium cast iron high frequency surfacing increase compared with the high chromium cast iron surfacing layer.
