The laser-cladding layeron the alloy consists of matrix phase of over-saturation solid solution γ and complexhexagonal carbide M_7C_3. Under certain condition, with fast laser scanning speed, the oversaturation solubility of elements increases in γ, and the precipitation of the complexcarbide M_7C_3 decreases, so that the microhardness increases and the wear resistance de-creases. But at slower laser scanning speed, more complex carbide M_7C_3 may precipitate, andthe wear resistance may be improved. Therefore, it is believed that the principal factor in im-provement over wear resistance is the precipitation of carbide M_7C_3, while overmicrohardness is the over-saturation solubility of elements in matrix phase.

表明：(1)激光熔覆合金层是由过饱和的γ基体相和复杂的六方M_7C_3碳化物相所组成(2)在其他参数不变的情况下，随激光扫描速度的提高，γ基体相过饱和度增大，而析出的碳化物含量减少，因而合金层的硬度升高，耐磨性有所下降；而降低激光的扫描速度，碳化物M_7C_3析出增加，有利于提高合金层的耐磨性、因此碳化物M_7C_3析出量是提高耐磨性的主要因素，而增加基体相γ的过饱和度则是硬度提高的主要因素
