应用低温镀铁工艺修复机件时,镀层与基体金属的结合是否良好,是评定镀铁质量优劣的基本条件。若二者结合不良,镀层在机件运用过程中会剥离脱落,拉伤与镀铁层配合的面。所以,在用低温镀铁工艺恢复磨耗件尺寸时,必须保证镀层与基体金属的结合质量。 1979年,我厂用低温镀铁工艺为蒸汽机车阀杆恢复尺寸,并在长 Application of low-temperature iron plating process repair parts, the coating and the substrate metal is good, is to assess the quality of the basic conditions of iron plating. If the combination of the two is poor, the coating will peel off during the use of mechanical parts, pulling the surface with the iron plating. Therefore, the use of low-temperature iron plating process to restore wear parts size, the coating must ensure that the quality of the base metal bonding. In 1979, I plant with low temperature iron plating process for the recovery of steam locomotive stem size, and long
