Influence of KF Concentration on the Coating Performance of SiCn/Mg Composites
Abstract:
The network SiC ceramics was prepared by organic foam impregnation and pressure-less sintering technology. The co-continuous SiCn/Mg composites were fabricated by vacuum infiltration methods. The results proved that coarse surface was observed on the surface of SiC network ceramics, which was helpful for interface reaction of metal alloy during impregnation process. The continuous interface can be formed in the SiCn/Mg composites. KF concentration had more important influence on coatings morphologies and polarization behaviors of SiCn/Mg composites during micro-arc oxidation process.Key words: Interpenetrating, Ceramic Coatings, Micro-arc Oxidation
