摘要： An improved process for applying a coating to an untreated ferrous metal substrate is disclosed. The substrate does not need to be phosphated or subjected to any other conversion coating prior to treatment. The process includes contacting the substrate surface first with a solution comprising a Group IIIB and/or IVB metal-containing compound and a nitrate, and then with a second solution comprising a reaction product of an epoxy and an amine, phosphorus or sulfur-containing compound. A film-forming resin is then deposited on the substrate and cured. Substrates treated by the process of the present invention demonstrate excellent corrosion resistance and are also disclosed herein.
