Project Coordinator:
Faculty of Technology and Metallurgy Belgrade
Participants:
IHTM - Institut of electrochemistry Belgrade
Project Manager:
Dr Đorđe Janaćković
Number of Researchers:
8
Aim and Scope:
Investigation of the mechanism of electrodeposition, morphology and corrosion resistance cerium coatings on aluminium alloy AA6060.
Major Results:
In a series experiment were demonstrated that treatments aluminium alloys with aqueous solutions of cerium salts effectively inhibit corrosion process. It is shown that Ce based coatings were good replacement of the chromate conversion coatings. Conversion coatings were applied by different methods: dip-immersion and electrolytic. Cerium layer consisted of a crystalline film of Ce7O12, a reduced form of CeO2 and an amorphous hydrated layer containing Ce3+ and Ce4+ ions.
