Research on the Preparation of Magnesium Alloy Micro-Arc Oxidation Black Ceramic Membrane

Article Preview

Abstract:

Black ceramic membranes are made on the surface of AZ31B magnesium alloy to further study the micro-arc oxidation coloring ceramic membranes with more colors.In the system of sodium silicate - copper sulfate, black ceramic membrane with good compactness and uniform color can be made while the concentration of sodium silicate is 20g/L and the concentration of copper sulfate is 1.0g/L. Experimental results show that the chroma of the membrane varies from light color system to deep color system with the increasing content of copper aluminum compounds.
