【Abstract】 The variation of color of Sn-salt electrolytic coloring oxlde film with the Sn-content in the oxide film is studied. The role of Ni2+ and Fe2+ in the mixed salt electrolytic coloring process is discussed. In the experiment the color of the oxide film was determined by using Coloring Difference Meter. The Sn-content in the oxide film was determined by using chemical analysis method. The Ni-content and Fe-content in the oxide film were determined by using TN-5500 X-ray Energy Spectrum Meter. The Results show that the color of the oxide film darkens gradually with the Sn-content in the oxide film increasing, but their relation isn’t a simple linear rule. in the Mixed Salts electrolytic coloring process, codeposition of Ni2+, Fe2+ with Sn2+ can occur, but H2SO4 concentration and SnSO4 concentration in the electrolyte have a great effect on the Ni-content and Fe-content in the oxide film.更多还原
