针对目前国产的各种通风机、鼓风机等产品普遍存在的叶片使用寿命低的严重问题,采用镍(Ni·wo)、钴(Co·wo)基自熔合金的激光熔覆处理办法,在低碳钢或低合金钢表面上获得具有高耐磨性、抗蚀性的涂层。实验表明:涂层的凝固行为受基材表层组织状态影响;在不同处理条件下,得到的组织不尽相同;在现有功率密度条件下,涂层较厚时,不同层深处组织不均 In view of the serious problem of low lifespan of blades that commonly exist in various domestically produced fan and blower products, the laser cladding method using nickel (Ni), cobalt (Co) Carbon steel or low alloy steel surface with high wear resistance, corrosion resistance of the coating. The experimental results show that the solidification behavior of the coating is affected by the surface texture of the substrate. Under different processing conditions, the obtained microstructures are different. Under the existing power density conditions, when the coating is thick,
