Abstract Three kinds of light-group sensitive materials are chosen to incorporat into primer coating, coated on the aluminum alloy surface, so as to make sure their light sensitive performance for the early prediction of corrosion of the aluminum alloy. The relation between the characteristic changes of light-group sensitive materials in coating and corrosion rate was studied. The sensitivity of light-group sensitive materials for corrosion detection was discussed. Primary connection mode between the coating and the concentration of light-group sensitive materials is set up. Finally, the mechanism of the light-group sensitive coating for detecting corrosion of the aluminum alloy is analyzed. It is found that, the three kinds of light-group sensitive materials in the coating predicted efficiently the corrosion rate of the aluminum alloy substrate.
