近几年来,我厂采用刷镀技术为本厂和兄弟单位修复了数百种机械零件,取得了较明显的经济效益。最近我们又引进了银镀液,经多方面的试验,已将该工艺应用到发电厂的部分电气设备中,如导电杆、接线开关、静触点、导块等,已提高电气设备部分零部件的导电性。现分四方面介绍如下: 一、导电杆对银镀层的技术要求导电杆对银镀层的技术要求主要有两方面,一是要求镀层表面光洁平整,光洁度达5以上,且基体与镀层结合牢固;二是要求镀后的导电杆能达到规定的电气性能指标。尺寸为φ30×576毫米的导电杆(材质为紫铜),分如图所示的三段进行了选择性镀银。为了保证导电杆具有良好的导电性和耐磨性,
In recent years, our factory uses brush plating technology to repair hundreds of mechanical parts for our factory and brother units, and has made obvious economic benefits. Recently, we introduced silver plating solution. After many experiments, this technology has been applied to some electrical equipment in power plants, such as conductive rods, wiring switches, static contacts, Conductivity of the part. Now divided into four areas are described as follows: First, the technical requirements of conductive silver bar on the conductive layer Silver bar on the technical requirements of the conductive layer there are two main aspects, first, require smooth coating surface finish, finish 5 and above, and the substrate and the coating combination of firm; The second is required after plating conductive rod can achieve the required electrical performance indicators. The size of φ30 × 576 mm conductive rod (made of copper), divided into three sections as shown in the selective silver plating. In order to ensure that the conductive rod has good conductivity and abrasion resistance,
