Abstract

Electrochemical cleaning processes generally use preheated (50-60°C) concentrated alkaline type soaps together with a low voltage current that can either be direct, reverse, or periodic. The effect of this cleaning process on metal surface and its influence on long term strength on metal-adhesive bonding is superior to normal industrial cleaning processes such as immersion or soaking, rotary and spray wash. Therefore, in this electrochemical cleaning and electro-rinsing method, the metal parts are treated in hot alkaline, hot acid solutions with anodic current prior to bonding, The metal surface electrochemical/electrorinse anodizing process was used in order to improve the metal surface and activate it for long term strength bonding.
