Omfang

Purpose This specification establishes the requirements for chemical-film (conversion) coatings on aluminum alloys. Application This process has been used typically for increasing the corrosion resistance of aluminum alloy parts, as a base for paint or other organic finishes, and for repair of abraded surfaces or discontinuous anodized coatings on aluminum alloy parts, but usage is not limited to such applications. AMS2477 is intended for applications that include electrical bonding requirements. Classification Chemical coatings covered by this specification are classified as follows (see Ordering Information): Type I - Hexavalent chromate treatment Type II - Trivalent chromium treatment Type III - Phosphate treatment Type IV - Silicate treatment Type V - Oxide treatment When no type is specified, any type may be supplied (see 3.1, 3.4.3, and 4.4). Safety - Hazardous Materials While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards that may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved. Authority The cognizant engineering organization (CEO) may impose requirements or approve allowances that supersede the requirements in this AMS.
