电镀梨底硬铬的质量控制方法

Quality Controlled Method of Hard Chromium Plating which Like Pear's Skin

根据某些工件对电镀硬铬层表面粗糙度的使用要求,经过一系列的试验,通过机件毛坯抛光后增加喷砂处理及对电镀工装、工艺采用一些有效的控制手段进行电镀梨底硬铬,满足了工件使用中对硬铬层硬度和粗糙度的要求。根据不同的基材选择合适的砂型进行喷砂处理和镀后没有修饰的一次电镀硬铬成型工艺是解决电镀梨底硬铬的关键所在。

According to some workpieces' usage demands of the rough degree on the surface of hand chromium plating, through a serial of experiments, we have satisfied the requirements of the using workpieces' hard chromium layer's consistence and rough degree through adding sand-blast treating to the workpieces' which are not dealt after polishing and adopting some effective control ways to the plating frock and craft, thereby carrying out plating hard chromium like pear's skin. According to different backing materials, we can choose the suitable grain size to sanding-blast treating and shape hard chromium plating that isn't shaping after being plated, Which is the key to solve hard chromium plating like pear's skin.
