Abstract

In a process to manufacture metallic objects e.g. foil, sheet metal components or formed components bearing a photo-catalytic active surface, the active material is applied as a cold gas spray incorporating a ceramic oxide and a metallic powder. The cold gas incorporates titanium dioxide powder e.g. Atanas. The individual ceramic oxide particles are encased within a metal or metal alloy representing 30-60% Vol. The metal surface has a photo-catalytic particle coating represents 30-80% of the surface area. The outer layer is subject to further mechanical or chemical treatment.
