Abstract
A method of fabricating and inspecting a part, the method including the following steps a) treating a substrate including aluminum by a chemical conversion method making use of a treatment solution including chromium with a degree of oxidation of +III in order to obtain a part presenting a chemical conversion layer; and b) inspecting the presence of the chemical conversion layer obtained during step a) by using a colorimeter to measure the color of the chemical conversion layer and by comparing the measured color with a reference color.
