Keywords: aluminum alloys; anodicaluminumoxidation; interference-enabled color production; rainbow effect; structural color; Introduction
Due to the low cost, high mechanical strength and ductility, and well-developed
production procedures, aluminum alloys have been extensively used as nonferrous structural materials [1][2][3][4][5][6][7][8][9][10][11][12]. Aluminum alloys are generally prepared by doping aluminum with other elements at a low content [13]. Anodicaluminumoxidation processing and electrodeposition
