  • Trivalent chromate conversion coating
    Patent number: 7029541
    Abstract: In a preferred embodiment of the present invention, a conversion coating composition comprising chromium (III) ions, cobalt (II) ions, and nitric acid is provided. The coating composition is substantially free of chromium (VI) ions and substantially free of an oxidizing agent. The present trivalent chromium based conversion coating provides corrosion protection equal to or greater than most hexavalent chromium conversion coatings.

  • Black trivalent chromium chromate conversion coating
    Publication number: 20040156999
    Abstract: A composition and method for providing a blank chromate conversion coating is provided. The composition is substantially free of hexavolent chromium and provides a black finish, on zinc or zinc alloy coatings. The composition includes trivalent chromium ions, phosphorous anions, anions selected from the group consisting of sulfate ions, nitrate ions and combinations thereof, at least one of a transition metal or metalloid from Groups III, IVa, Va or VIII, and an organic chelate selected from the group consisting of carboxylic acids, polycarboxylic acids and combinations thereof.

  • Non-chrome conversion coating
    Patent number: 6027578
    Abstract: A chrome-free conversion coating composition for use over zinc-plated metal comprises a combination of a transition metal oxide, and a polyhydroxy aromatic to provide a coating that eliminates environmental concerns regarding chromium disposal. Aluminum chlorohydrol is also included in the composition to provide an aesthetically pleasing blue appearance. The conversion coating composition is combined with water to form a bath. Zinc plated metal is immersed in the bath to apply the coating.
