【Abstract】 The microstructure characteristics of micro-arc oxidation ZL109 alloy and SiC p/ZL109 aluminum matrix composite material were studied by SEM, and their hardness were compared. The results indicated that ZL109 alloy and SiC p/ZL109 aluminum matrix composite both can be micro-arc-oxidized and the oxidized surface consists of two parts: the loose layer and the compact layer. The oxidation layer of ZL109 alloy comprises Al 2O 3 phases with different structures, and the oxidation layer of SiC p/ZL109 consists of Al 2O 3 and MgA1 13 O 40 . Moreover, the formation reason of the oxidation layer has been analyzed.更多还原
