【Abstract】 The microplasma oxidation characteristic of TA1 Ti in different electrolyte system was studied, and as the suitable electrolyte system of microplasma oxidation the hypophosphitemetaaluminate was defined. The characteristic of oxidation processes and the pitting corrosion resistance of this ceramic film were analyzed at different current density and NaAlO₂ concentration. The film was found to be a mixture of Al₂TiO₅ and TiO₂ by Xray diffraction （XRD）.更多还原
