SAE AMS2479E-2024 - Anodic Treatment of Magnesium Alloys Acid Type, Thin coat

Scope: This specification establishes the engineering requirements and properties of coatings produced by acid-type anodic coatings on magnesium alloys. The process is generally used to increase corrosion and wear resistance and to provide a surface that ensures maximum paint adhesion, but use is not limited to such applications. The process is suitable for all magnesium alloys, provided proper allowance is made for dimensional changes. It should not be used for parts that are subject to flexing in service. Wear resistance is not as high as that of the alkaline electrolytic treatment of AMS2476 or the full-coat acid treatment of AMS2478, but other properties are comparable when similarly painted or resin coated. Although the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not deal with the hazards that may be involved in such use. It is the user's responsibility to become familiar with the safe and proper use of any hazardous material and to take the necessary precautions to ensure the safety and health of all persons involved.
