Abstract
So as to solve the chemical conversion challenge of various metals in a cell at the same time, a process technology with complex formula of fluoroziconate/ fluotitanate and some addictives used on aluminum alloy/steel and other metallic materials was studied. Investigated influence of the zirconium fluoride acid salt, film forming additive, technological parameters such as pH, temperature, time on conversion coating color, golden yellow and blue color coating were produced on aluminum alloy and steel respectively. Tafel polarization curve showed that the bare aluminum alloy corrosion resistance improved significantly. By virtue of Energy Dispersive Spectrometer (EDS), its' results show that Al/Ti/Mo/O/F and a small quantity of C are the main composed elements of the film. And X-ray Photoelectronic Spectroscopy (XPS) demonstrated that the combined compound of each elements are Mo2O5/MoO3/TiO2/MgF2.
