The Role of Polymeric Complexes in Phosphatizing Treatments 800444

The paper discusses the required mechanism in producing on automotive steel, on galvanized steel, and on joints between them, protective phosphate treatments based on a chemical interreaction of the phosphate carrying solution and an introduced metal-oxide, and with water dispersed organic polymer components acting as ligands in the reaction coating. Methods of the identification of such interreactions are explained, as well as the methods of analyzing the reaction product formations on the metal surfaces.
