Abstract
ⶠThe deposition of rare earth conversion coatings on aluminum alloys and other metals is considered as an effective method to replace chromate conversion coatings which have been prohibited in many fields for their toxicity. ⶠHowever, most of the reported methods to prepare cerium oxide based coatings were based on electrodeposition or chemical conversion processes. ⶠThe addition of hydrogen peroxide results in cerium precipitates and solution instability. ⶠDeposition solutions with H2O2 are also difficult to recycle. ⶠIn this study, a cerium oxide-based coating was deposited on aluminum alloy 2024 by brush. ⶠThe brush plated cerium oxide based coatings on aluminum alloy showed good corrosion resistance. ⶠH2O2 is not necessary in the brush plating solution. ⶠThe influence of the plating parameters on structure and corrosion resistance of the cerium oxide based coatings was studied.
