Abstract

The invention provides a method for preparing an iron / amorphous iron silicon boron wastewater composite degradation coating on the surface of a magnesium alloy, and relates to a method for compositely plating a film on the surface of metal. The method comprises the following steps that firstly, an anode oxide film of the magnesium alloy is prepared in a mixed solution containing with sodium hydroxide, aluminum hydroxide, ammonium bifluoride and sodium phosphate; and then electro-deposition is carried out on the surface of the anode oxide film of the magnesium alloy in iron and iron silicon boron amorphous powder. According to the method, the high wastewater degradation capacity and the interface bonding force are shown in the obtained coating, and the obtained coating has the beneficial effects of being good in corrosion-resistant performance and recycled.

Description
