CHEMICAL CONVERSION MATERIALS FOR COATING ALUMINUM AND ALUMINUM ALLOYS
Organization:
NAVY - AS - Naval Air Systems Command
Year: 2006
Abstract: This specification covers chemical conversion materials used in the formation of coatings by the reaction of the material with the surfaces of aluminum and aluminum alloys.Intended Use: The conversion coatings covered by this specification are intended for use, throughout the Department of Defense, on aluminum and aluminum alloy substrates that are not anodized. They are used to repair anodize coatings on aluminum. They are designated as a post treatment to ion-vapor deposition (IVD) aluminum used on many military platforms as a cadmium alternative or galvanic corrosion inhibitor. Type I and II conversion coatings provide corrosion protection on unpainted items, as well as improve adhesion of paint finish systems on aluminum and aluminum alloys. Conversion coatings covered by this specification exceed commercially available products due to the nature of their use on aircraft. All conversion coating applications in accordance with this specification are assumed to use type I unless the use of type II is specified. Type II may not be substituted for type I, for either Class IA or Class 3, unless authorization for its use is given by the acquisition activity or engineering authority for the system or item on which the conversion coating is applied.Class 1A.Class 1A materials covered by this specification are intended for use in the formation of chemical conversion coatings which are corrosion preventive films and will improve adhesion of paint finish systems to aluminum and aluminum alloys.Class 1A, form VI, method D.Class 1A, form VI, method D materials covered by this specification are intended for use in the formation of conversion coatings for repair or touchup applications which are corrosion preventive and will improve adhesion of paint finish systems to aluminum and aluminum alloys.Class 3.Class 3 materials covered by this specification are intended for use in the formation of chemical conversion coatings which are corrosion preventive films for electrical and electronic applications where low resistance contacts are required.Relationship with MIL-C-5541.The materials that have been approved in accordance with the requirements of this document and have been accepted for listing on the applicable qualified products list are used to produce coatings conforming to MIL-C-5541. MIL-C-5541 covers the requirements for chemical conversion coatings formed by the reaction of materials qualified to this specification and applied to the surfaces of articles, items, parts, or components made of aluminum and aluminum alloys.
