| titleOfInvention | Process for forming a cobalt conversion coating on an aluminum or aluminum alloy substrate and the chemical conversion coating solution for use in the process |
| abstract | A improved process that is commercially practical for forming an oxide film cobalt conversion coating exhibiting corrosion resistance and paint adhesion properties on a substrate, wherein said substrate is aluminum or aluminum alloy, said process comprising the steps of: (a) providing an oxide film forming cobalt conversion solution comprising an aqueous reaction solution containing a 3-valent cobalt complex prepared by reacting the following starting materials: (1) a cobalt-II salt wherein said cobalt-II salt is CoX2 where X = C1, Br, NO3, CN, SCN, 1/3PO4, 1/2SO4, C2H3O2, or 1/2CO3; (2) an ammonium salt wherein said ammonium salt is selected from the group consisting of ammonium nitrate and ammonium acetate; (3) one or more inorganic complexing agents selected from the group consisting of a soluble metal carboxylate, a soluble metal nitrite, and ammonia; (4) a water soluble amine wherein said water soluble amine is selected from the group consisting of ethylenediamine, triethanolamine (TEA), and ethylenediaminetetraacetic acid (EDTA); and (5) an oxidizing agent; and (b) contacting said substrate with said aqueous reaction solution for a sufficient amount of time to oxidize the surface of said substrate, whereby said oxide film cobalt conversion coating is formed, thereby imparting corrosion resistance and paint adhesion properties to said substrate. |
