Research of Chemical Film Process on Metal Surface

摘要

In the article we selected polyethylene glycol(400), triethanolamine, silane coupling agent, chrome alum, glycerin as the main raw material, and systematic studied the chemical adsorption film technology on metal surface by using one step. Through the preliminary experiments, we optimized the optimum technological conditions. The trial results showed that the process and procedures to deal with were simply, and the tank liquor was stable. The chemical adsorption film accumulation was closely, and it had stable structure. It had a good anti-base metal corrosion, and significantly enhanced the adhesion of metal coatings.
