摘要:
高压开关设备内核心零部件压气缸为6063铝合金材质，外表面进行电镀银层，内腔进行硬质阳极氧化处理。本文针对该零件电镀银层脱落造成放电的一起事故，通过对镀层脱落部位基体及脱落镀层底面进行成分分析，确定剥离部位为中间过渡铜层。通过对不合格零部件加工过程排查，确定此次放电的原因是压气缸工装挂具导电不良造成银镀层附着力不良，高压开关设备运行过程中，镀层经受外力反复摩擦脱落，引起产品放电。后期为规避此类问题，提出了该类核心零部件电镀银过程中，关键控制点及问题的规避方案，为电镀银表面处理产品工艺过程控制，提供参考依据。
Abstract:
The pressure cylinder of the core parts in the high voltage switchgear is made of 6063 aluminum alloy. It is plated with a silver layer on the outer surface and undergoes a hard anodized treatment on the inner cavity. This article discusses an incident caused by the silver peeled off. By analyzing the composition of the substrate and the bottom surface of the peeled coating, it was determined that the peeling occurred at the intermediate copper layer. It was identified that the cause of the discharge was poor conductivity of the fixtures, resulting in poor adhesion of the silver coating. During the operation of the high voltage switchgear, the coating experienced repeated friction and detachment due to external forces, leading to product discharge. To avoid such issues in the future, key control points and problem mitigation strategies were proposed for the silver plating process of these core parts. This provides a reference for process control in the silver plating surface treatment of products
