| 英文摘要 | Ceramic coating on the surface of die casting Al alloy ADC12 with high Si content has been prepared by micro-arc oxidization (MAO) in an electrolyte containing Na(2)SiO(3) and Na(3)PO(4) as its major compositions at constant current density. The testing results of hardness and corrosion protection indicate that the obtained ceramic coating has relatively high microhardness (HV up to 1430) and could provide effective protection to substrate. Eddy currency thickness measurement and SEM micrographs manifest that the ceramic coating consists of a double-layer structure and its thickness is relatively even. EDX and XRD analyses reveal that the main elements in the coating are O, Al, Si as well as P, and that the main phases are gamma-Al(2)O(3), alpha-Al(2)O(3). In addition small amounts of chi-Al(2)O(3), theta-Al(2)O(3) and Al(2)SiO(5) are also detected. |
