| Anodizer | |
| I plan to add pictures related to anodizing as I have more time. I currently anodize aluminum and titanium. | |

A picture of the aluminum anodizer in
action. Not terribly sophisticated. A five gallon bucket with an
electrolyte solution, sulfuric acid in this case, a ten amp battery
charger, an anode made from some stainless steel wire with a piece of
aluminum foil wrapped over it, and a coil of wire to be anodized. When the charger is turned on it causes a layer of oxide to form on the surface. The surface is porous, like tiny tubes stacked close together. Once the layer is formed, about an hour, the piece is placed in a strong dye solution and allowed to absorb the dye for a few minutes. The surface is then sealed by placing the piece in boiling water which closes the tops of the tubes. The anodized layer is very hard and durable. |
