【Abstract】 20200 μm ceramic oxidation coatings are in situ formed on the surface of aluminum alloys by plasma micro arc oxidation. The ceramic oxidation coatings with very high hardness improve significantly the abrasive resistance and corrosion resistance of the aluminum alloys. Besides the requirements of high abrasive resistance and corrosion resistance, the surface resistance should be controlled in the range of 10 6 ~10 10 Ω for some electronic components requiring high antielectrostatic property. The surface resistance of the electronic components can be successfully controlled by adjusting the thickness of the ceramic oxidation coatings produced by plasma micro arc oxidation technique.更多还原
