Description / Abstract:

Purpose:

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

Applications:

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

This process is applicable to all magnesium alloys provided 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 AMS2478 but, when similarly painted or resin-coated, other properties are equivalent.
