Claims2
An article comprising:
- a metal body;
- an anodized surface on said metal body;
- and
- polynuclear clusters comprising aluminum oxide hydroxide, disposed on said anodized surface, wherein the polynuclear aluminum oxide hydroxide clusters comprise complexes according to the formula:
- [AlO4Al12(OH)24(H2O)12]7+*[(7/n) X−n]7− where X−n represents ‘−n’ charge-bearing X counter-ion species and (7/n) X−n are needed to neutralize the total complex charge.
