| Abstract: | A ceramic layer was prepared on LY12 substrate by micro arc oxidation.The microstructure and tribological properties of the layer were analysed.The results show that the layer includes a external porous region and a internal denser one,the denser consists of Al Si O and Al 2O 3 phases.The ceramic layer has good combination with the substrate,its hardness is over HV1700,and its wear resistance equal or superior to the hard alloys. |
