目前修理内燃机车磨损件的做法主要是用新件更换磨损的零件,或者用传统的堆焊金属的方法来修复工作面。这样就需要消耗大量的材料、劳动力和费用。沙德林内燃机车修理厂与全苏铁路运输科学研究院乌拉尔分院一起,研究并采用了一种新的以铁基复合电化学镀层修复内燃机车零件的高效、废品率低的工艺方法。该方法不仅可以将零件的工作表面修复到原尺寸,而且可以提高零件的工作可靠性和延长其使用寿命。复合镀铁方法是基于悬浮液中的电解铁和分散在溶液中的添加物微粒-粒度为M,的白色电刚玉(?)24-A在阴极共同沉积。为了
At present, the repair of wear parts of diesel locomotives is mainly to replace the worn parts with new ones or to repair the working face by using the traditional method of surfacing the metal. This will consume a lot of material, labor and costs. Shadlin diesel locomotive repair shop and the All-Soviet Railway Institute of Transportation Ural Branch together to study and adopt a new iron-based composite electrochemical coating to repair parts of diesel locomotives with high efficiency, low scrap process. The method can not only repair the working surface of the part to its original size, but also improve the reliability of the part and prolong the service life of the part. The composite iron plating method is based on electrolytic iron in suspension and additive particles dispersed in solution - white fused alumina (-) 24-A having a particle size of M co-deposited at the cathode. in order to
