现在,各机车车辆修理企业很重视节约和合理利用备件和材料,特别是在修理时修复和重复利用品种繁多的机车车辆还可使用的旧零件。为了提高这一工作的效益,在工厂和车辆段内研究和采用除传统的堆焊和焊接方法以外的其它新的工艺过程有着重要的意义。全苏铁道运输科学研究院乌拉尔分院为车辆修理企业研制和验证了一种能节约金属的高效率电解复合镀铁工艺。在工业部门利用一般非复合镀铁来修复各种零件的配合面、固定结合面和移动量小的结合面,例如 Nowadays, the locomotive and vehicle repair enterprises attach great importance to the economical and rational use of spare parts and materials, especially the old parts which can be used for repairing and reusing a large variety of locomotive and rolling stock while repairing. In order to improve the efficiency of this work, it is of great significance to study and adopt other new processes in addition to the traditional surfacing and welding methods in factories and depots. All-Urals Railway Transportation Research Institute of Urals Branch for the vehicle repair business developed and verified a metal-saving high-efficiency electrolytic composite plating process. In the industrial sector using the general non-composite plating iron to repair the various parts of the mating surface, the fixed surface and the combination of a small amount of movement, such as
