Abstract

Purpose  This specification covers the requirements for a hard anodic coating on magnesium alloys and the properties of the coating.  Application  This hexavalent chromium free and hazardous air pollutants free coating has been used typically to provide corrosion resistance and abrasion resistance to cast magnesium alloys and to produce a surface suitable for subsequent application of protective organic finishes, but usage is not limited to such applications.  Classification  Anodic finishes are classified by coating thickness as follows:  Class 1 - Thin Coating: Coating thickness in the range of 0.0002 to 0.0004 inch (5 to 10 µm).  Class 1H - Heavy Coating: Coating thickness in the range of 0.0005 to 0.0007 inch (13 to 18 µm).  Class 2 - Thick Coating: Coating thickness in the range of 0.0008 to 0.0010 inch (20 to 25 µm).  Class 3 - Thin Touch-up Coating: Coating thickness less than 0.0002 inch (5 µm).  Class 3H - Thick Touch-up Coating: Coating thickness in the range of 0.0001 to 0.0003 inch (3 to 8 µm).  If an anodize class is not specified, Class 1 shall be supplied. If a touch-up class is not specified, Class 3H shall be supplied.  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 that 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.  Authority  The cognizant engineering organization may impose requirements or approve allowances that supersede the requirements in this AMS.
