Silane Treatment Technology on Aluminum Surface
Silane surface technology have been rapidly developed in the field of anti-corrosion of metals as one of the “green” replacements for conventional chromizing. The article introduced the corrosion prevention mechanism of silane treatment; factors affecting performance of the silane film(including silane categories, the concentration and pH of the silane solution, and deposition methods); modified technologies(such as loading nanoparticles, doping corrosion inhibitor and adding suitable dyes and colorants); analytical and characterization techniques of the silanizing film. The shortage that existed currently in silane treatment is also discussed. All above are aimed to promote the research of environmental friendly surface passivation technology on aluminum alloy.
