MIL-DTL-32459, DETAIL SPECIFICATION: COATINGS, ANODIC FOR MAGNESIUM AND MAGNESIUM ALLOYS (25-JUN-2013)

MIL-DTL-32459, DETAIL SPECIFICATION: COATINGS, ANODIC FOR MAGNESIUM AND MAGNESIUM ALLOYS (25-JUN-2013)., This specification covers the general requirements for the application and inspection of applying an anodic, hexavalent chromium-free and HAP (Hazardous Air Pollutants) free coating to magnesium alloys parts, newly developed and/or used parts that have been stripped and cleaned down to the base metal (magnesium alloy). These coatings will provide corrosion protection and abrasive resistance properties to magnesium base metals, including magnesium alloys and to produce a surface suitable for the subsequent application of a protective organic finish (see 6.1), as applicable. This specification (Types I, II, and III) is intended to provide the requirements needed to apply immersion anodic, hexavalent chromium-free and HAP (Hazardous Air Pollutants) free coatings to magnesium alloys for the purpose of increasing their corrosion and abrasion resistance, and to produce a surface suitable for the subsequent application of a protective finish. Type IV and Type V coatings are intended for touchup and repair of existing coatings.
