利用5kWCO2激光器激光熔覆Al合金表面的Ni－Cr－Al涂层，SEM与TEM分析结果表明，在激光熔覆层中的非晶组织呈空间扭曲薄片或杉叶状，它们分别存在于熔覆层颗粒间白色网状组织与颗粒中,利用差热分析（DTA）半定量测定熔覆层中的非晶含量，功率密度，扫描速度对非晶含量有较大的影响
The surface of the Ni-Cr-Al coating was laser cladded with 5kW CO2 laser. The SEM and TEM analysis showed that the amorphous structure in the laser cladding layer was spatially distorted flakes or cedar, which were present in the cladding Amorphous content, power density and scanning speed of semi-quantitative determination of the amorphous content in the layer of white meshes and particles by differential thermal analysis (DTA)
