Abstract:
The present invention relates to a method and an apparatus for coating large area solid substrates with metal based alloys or compounds by contacting the substrate surface with an unoxidised metal powders formed by in situ reaction of a metal halide and a reducing agent. The method is suitable for coating large area substrates such as flakes, powder, beads, and fibres with metal based alloys or compounds starting from low-cost chemicals such as metal chlorides. The method is particularly suited for production of substrates coated with metals, alloys and compounds based on Zn, Sn, Ag, Co, V, Ni, Cr, Fe, Cu, Pt, Pd, Ta, Nb, Rh, Ru, Mo, Os, Re and W.

Claim (Index 5):
The method for forming a coating on a substrate according to  claim 1 , comprising:\n immersing a substrate powder in a reactant mixture comprising an uncoated metallic powder and metal chlorides and a reducing agent and optionally any coating additives, and heating the resulting mixture at temperatures between 400\u00b0 C. and 800\u00b0 C. to induce reactions between the substrate surface and the said mixture and form a coating on the substrate; and wherein the uncoated metal powder is formed by exothermically reducing a metal chloride precursor with a reducing agent; and wherein the reducing agent includes Na, K, Ca, Mg, or Al; and condensing by-products away from a reaction zone, where the reducing alloy and precursor materials are reacting; and condensing unreacted metal chlorides and returning them to the reaction zone; and separating the coated substrate from residual un-reacted materials.
