The response of hydrotalcite coated aluminum to sealing with transition metal salt solutions
Conference

OSTI ID:26008
Objective was to determine if the protective coating could be enhanced by filling intercrystalline spaces or by reinforcing the coating at intermetallic particles by exposure to aqueous transition metal salt solutions. Two oxy-anion analogs to chromate were used: permanganate and molybdate. Ce(III) (as Ce(NO{sub 3}){sub 3}) was also studied. (Al alloys 2024-T3 and 6061-T6 were used as substrates.) Results are summarized. 4 figs, 1 tab, 3 refs.
