| Alkaline anodizing of titanium is a process that forms a dense dark gray coating on aluminum. The coating is used to protect titanium parts from corrosion oxidation and pitting. The coating will render the surface nonconductive allowing it to be joined to aluminum assemblies with minimum galvanic impact. The coating can also be used to prevent oxidation and staining caused by handling titanium with bare hands. The alkaline anodizing of titanium imparts a gray lusterless finish to the titanium that provides an esthetically pleasing appearance. The coating makes a great pretreatment for solid film coatings protecting the titanium from degradation by the solvents found in the solid film lubricants when the parts are exposed to high temperatures. |
