ALUMINUM ALLOY SHELL AND MANUFACTURING METHOD MAKING THE SAME

摘要

An aluminum alloy shell (10) and a manufacturing method for making the present aluminum alloy shell are provided. The aluminum alloy shell includes a base shell (11) and a microarc oxidation coating (12). The microarc oxidation coating is formed on a surface of the base shell by micro arc oxidation processing. The manufacturing method includes steps as follows. The base shell is pretreated. The pretreated base shell is microarc oxidized to form the microarc oxidation coating thereon. The aluminum alloy shell is post treated by washing and drying.
