Anodic Treatment of Magnesium Alloys, Acid Type, Thin Coat AMS2479C

This specification establishes the engineering requirements for producing an acid-type, anodic coating on magnesium alloys and the properties of the coating.

This process has been used typically to increase corrosion and abrasion resistance and to provide surfaces which will ensure maximum paint adheresion, but usage is not limited to such applications.

This process is applicable to all magnesium alloys provided proper allowance is made for dimensional change. It should not be used for parts flexed in service. Abrasion resistance is not as high as is provided with the alkaline electrolytic treatment of AMS 2476 or the full-coat, acid treatment of AMS 2478 but, when similarly painted or resin-coated, other properties are equivalent.
