Abstract
A method of solid state anodization comprising contacting a solid anode with a solid insulator that separates and contacts the anode and a solid permeable cathode whereby an oxidant infuses through the permeable cathode while the anode is biased sufficiently positive to cause anodization.
Claims7
A method of solid state anodization using fluid infusion which comprises:
- (A) providing:
- 1. a solid anode,
- 2. a solid permeable cathode, and
- 3. a solid insulator that separates and contacts the anode and permeable cathode;
- (B) contacting the permeable cathode with an oxidant that infuses through the permeable cathode;
- and
- (C) biasing the anode sufficiently positive to cause the anodization.
