the application of a thin coating of metallic titanium to a material, usually steel, in order to improve corrosion resistance. Titanium cladding may be effected by the condensation of titanium vapors on the surface of an item, in which case titanium is melted and superheated using an electron beam in a deep vacuum. With this method, a titanium film can be applied to metals, as well as to glass and other materials.
The diffusion method of titanium cladding involves application of a special paste containing powdered titanium and subsequent annealing in a vacuum or a neutral medium. Titanium can also be applied by spraying. Cladding lowers the production costs of large autoclaves and other chemical equipment designed to handle highly corrosive substances. The lining of the interiors of steel tanks with thin sheets of titanium is also considered titanium cladding.
