渗碳

To avoid the forming of cracks in iron based laser cladding, the volume fractions of austenite and cemetite in cladding layers were adjusted through adjusting the contents of Ni. The claddings were produced on gray irons without preheating.

采用铁基熔敷材料，在不预热情况下通过调整熔敷金属Ni含量，改变铸铁激光熔敷层内奥氏体相与渗碳体相体积分数，进而抑制熔敷层裂纹的产生。
