PRC-5005 (REV. C), PROCESS SPECIFICATION FOR THE CHEMICAL CONVERSION COATING OF ALUMINUM ALLOYS

PRC-5005 (REV. C), PROCESS SPECIFICATION FOR THE CHEMICAL CONVERSION COATING OF ALUMINUM ALLOYS. This process specification covers the requirements for two classes of chemical conversion coatings formed by the reaction of chemical conversion materials and the surfaces of aluminum and aluminum alloys. Conversion coatings covered by this specification are intended to provide increased corrosion resistance and/or a surface having better paint adhesion than uncoated aluminum. They are not intended to be used for decorative applications.
