Chemical conversion coating formed by the 2024-T3 aluminum al oys as test material and alodine 1200S as reaction of chemical conversion material. During the manufacture process, the parameters including pretreatment, time of conversion, temperature of solution, pH value, post-treatment and temperature of drying were optimized to obtain no more than 5 isolated spots or pits on each test penal, which improved corrosion resistance of alodine 1200S chemical conversion coating. The results provide test evidences for alodine 1200S chemical conversion coating process on a certain type of aero-engine.
