激光熔覆是利用高能密度的激光束产生的快速凝固过程．在基材表面形成与基材相互熔合的、且具有完全不同的成分与性能的合金覆层．国内激光熔覆研究还仅限于实验室阶段，应用于生产实际中的例子较少，尤其对于多层熔覆试验研究甚少．本文将针对我室横向课题，在实际工件材质表
Laser cladding is a rapid solidification process using a laser beam of high energy density. An alloy coating is formed on the surface of the substrate, which is fused with the substrate and has completely different composition and properties. Domestic laser cladding research is still limited to the laboratory stage, the application of practical examples of less, especially for the multi-layer cladding test little research. This article will focus on my room horizontal topic, the actual workpiece material table
