Abstract

The effect of acidic chemistry on the accelerated growth of oxide on aluminium alloys Peraluman 706^TMand AA6060 under exposure to high temperature steam was investigated. Studied chemistries were based on citrates and phosphates. Results showed that the presence of citrate and phosphate anions initiate doxide growth at the intermetallic particles while growth and corrosion performance of oxide was found tobe a function of anions type and their concentration. Further, steam treatment with phosphates exhibited better performance under acetic acid salt spray and filiform corrosion test whereas delay in powder coating resulted in 1.5–3 times inferior performance.
