利用电刷镀修复大型贵重机件时想达到预想的效果,首先关键在选择好施镀规范和认真的工艺操作。例如,在为石河子热电厂修复第二根引风机轴时,该轴的磨损量单边厚度0.56毫米,对这样厚的镀层很难保证不发生剥离。我们采用快速镍分多次镀复的方法,先镀0.25毫米厚,然后车削,经车削未发生剥离,且车削很困难,不易进刀,说明镀层强度达到了预想的效果。接着用砂布打磨后又继续镀,镀到单边厚0.4毫米时,又进行机加工,结果 The use of brush plating to repair large expensive parts want to achieve the desired effect, the first key in the choice of plating norms and serious process operation. For example, when repairing the second draft fan shaft for the Shihezi Thermal Power Plant, the unilateral thickness of the shaft is 0.56 mm, making it difficult to ensure that no delamination occurs for such a thick coating. We use the rapid nickel multiple plating method, first plated 0.25 mm thick, and then turning, the peeling did not occur after turning, and turning is difficult, not easy to feed, indicating the strength of the coating reached the desired effect. Then polished with emery cloth and continue to plating, plated to unilateral 0.4 mm thick, then machined, the results
