经过刷镀修复的零件使用一段时间后,当镀层磨损超过允许范围时,必须进行再修复。如在原来的镀层上再刷镀,易剥离。为了保证原工艺要求,大多磨削加工或退镀,清除原有镀层和渗透层,这样不仅增加了修复成本,而且出现很多新问题。我们对原工艺作了改进,提高了镀层与母材的结合强度。 After brush plating repair parts use for some time, when the coating wear out of the allowable range, it must be repaired. If plating on the original plating, easy to peel. In order to ensure the original process requirements, most of the grinding or stripping plating, removal of the original coating and infiltration layer, so not only increased the cost of repair, but also many new problems. We made improvements to the original process and increased the bonding strength between the coating and the base metal.
