Description / Abstract:

All magnesium-rich alloy parts shall be prepared and given a complete protective treatment of cleaning, chromate treatment, sealing and painting in accordance with this specification. Other methods may be used subject to prior approval by the Director of Materials Research and Development.

The complete treatment involves operations on the material in its semi-finished form as a casting, forging, extrusion or sheet, with further operations after all forming and machining operations have been completed.

The standards of organic finishing laid down are minima. Extra coats of paint and/or erosion resisting coatings should be applied on parts subject to severe exposure to corrosion or mechanical damage.
