An environmentally friendly, non-chemical surface treatment has been developed as an alternative to phosphoric acid anodizing. This treatment is based on ion beam enhanced deposition of aluminum oxide (α-Al2O3) onto an aluminum alloy surface. Results of experiments are presented, demonstrating that the IBED surface treatment yields a surface which has improved resistance to corrosion in aqueous chloride solutions.
