Research Progress of Preparation Methods of Aluminum Protective Coating

Abstract

Applying aluminum protective coating is a common corrosion protection method for metal.In this paper,the preparation methods of aluminum protective coating were classified into the physical and chemical methods.Besides,the research progresses of physical preparation methods of aluminum protective coating such as the hot dip process,spraying and physical vapor deposition,as well as the electrochemical preparation methods of such coating were reviewed.Furthermore the development trend of the preparation methods of such coating was prospected.
