钢制实体保持架镀银表面缺陷分析

Surface Defect Analysis of Steel Sold Cage Sliver Plated

针对40CrNiMoA钢制实体保持架镀银后在其表面出现针刺状麻点缺陷问题,分析影响保持架镀银质量的多种原因,通过多项工艺试验表明:保持架表面贴附细小金属切屑,清洗过程很难去除,通过优化保持架光饰工艺,解决了钢制保持架镀银麻点缺陷,保证了镀银质量,满足了产品要求。

For 40CrNiMoA steel solid cage,acupuncture- like pitting defects appear on the surface after silver plating,and the a variety of reasons impacting silver plating quality are analyzed. Process test show that small metal chips attached to the surface are root cause of pitting,which are difficult to remove in cleaning process,and the steel cage silver pitting defects are avoided by optimizing the cage finishing process,ensuring the quality of silver plating to meet the product requirements.
