ABSTRACT:
A porous, sintered powdered metal article having excellent corrosion resistance is provided. A porous metal such as prepared from a sintered iron powder and suitable for further treatment is phosphatized with a solvent phosphatizing composition. The phosphatized metal is then coated with a chromium-containing coating composition. The thus treated powdered metal part may be further topcoated and, in either case, exhibits outstanding corrosion resistance.
