Chemical Conversion Coating

In order to prevent pitting corrosions in aluminum thin film, zirconium incorporated chemical conversion coating on sputtered aluminum film was studied. Several pretreatment methods for conversion coating on the thin film were examined. There existed the optimum pretreatment and coating condition for successful growing of anticorrosive conversion coating layer in a given aggressive environment. Pit densities of aluminum thin films were significantly decreased with conversion coating. Electrochemical behaviors of conversion coated aluminum thin film were also discussed.

An environment-friendly non-chromium chemical conversion coating was obtained from fluozirconate/fluotitanate acidic solution for the corrosion protection of AA 5083. The surface morphology, composition, electrochemical behavior and corrosion resistance of this coating were investigated. The coating was found to be a homogeneous and dense layer consisting of nano-size particles, of which the major component was compound oxides consisted by Al, Mg, Zr, Ti, F and O. The results of electrochemical measurements, immersion and natural salt spray (NSS) tests demonstrated that the corrosion resistance of the AA 5083 H-116 was improved by the nano-sized non-chromium chemical conversion coating considerably, which was most attributed to the great inhibitive action on the anodic dissolution by acting as a protective barrier layer.
