| 摘 要： | 介绍了一种用于ZL101铝合金的镀银工艺,其主要流程包括除油、除垢、酸蚀、沉锌、镀铜、镀银、活化、打保护剂等。酸蚀时采用由2体积份浓硝酸、1体积份水及少量HF组成的溶液,沉锌时加入自制的除气粉,以及电镀时将内孔中的气体排出,都能有效避免镀层起泡。

| Abstract: | A process for plating silver on cast aluminum alloy ZL101 was introduced.The process flow mainly includes degreasing,descaling,pickling,zinc dipping,copper electroplating,silver electroplating,activating and coating protective film.Using a solution composed of 2 volumes of concentrated nitric acid,1 volume of water and a small amount of hydrofluoric acid,adding a home-made anti-bubbling powder to zinc bath,and removing gases from internal holes during electroplating are effective methods to eliminate the bu... |
