Abstract
The chemical conversion film formed on magnesium alloy was investigated by using the colloidal silica with some parameters such as solution pH, temperature, solution conditions, and treatment time. Moreover, the solutions consisted of colloidal silica, titanium sulfate, and cobalt ions were used for the colloidal silica film to having a good corrosion resistance and adhesion properties. It was thought that the film at 298 K was made with combination of Si-O. The quantity of film formed at high temperature such as 333 K and 353 K is smaller than dissolved quantity during chemical conversion treatment. Adding CoSO4 to the colloidal silica solution enhanced the adhesion force between the silica film and magnesium substrate. The optimum conditions for the chemical conversion treatment solution were pH 2, 90 s treatment, and 298 K.
