Description / Abstract:

Purpose:

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

Application:

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 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.

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 which 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.
