本规范涵盖了对镁合金零件、新开发和/或使用的零件（已剥离并清洗至母材（镁合金））施加阳极、六价铬和HAP（有害空气污染物）涂层的一般要求。这些涂层将为镁基金属（包括镁合金）提供防腐和耐磨性能，并产生一个适合后续应用保护性有机涂层（见6.1）的表面（如适用）。

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.
