摘要： In order to improve adhesion of Cr(VI)-free primers and suitable topcoats on aircraft parts, a method for anodising part surface of the aircraft part that includes aluminium or an aluminium alloy is proposed. The part is cleaned and exposed to an anodising electrolyte. During anodising it is essential that the temperature of the anodising electrolyte is maintained at a constant temperature chosen from a range from 42 °C to 60 °C. This results in a surprising surface morphology that improves adhesion of primers and/or topcoats on the aircraft part.
