Abstract
In this paper, a hard and thin coating with no loose layer was formed on the surface of the aluminum LC4 by bipolar micro-arc oxidation power, and the influence of ratio J of the negative current density to the positive current density on the thickness h and the hardness H of micro-arc oxidation coatings was studied. By SEM and other modern materials testing and analyzing techniques, the microstructures of the micro-arc oxidation ceramic coatings were tested and analyzed. It was showed that the micro-structure is compact, and the ceramic coating almost has non-porous layer.
