METHOD AND APPARATUS FOR APPLYING METAL CLADDING ON SURFACES AND PRODUCTS FORMED THEREBY ABSTRACT OF THE DISCLOSURE Small, preferably micronsized hollow glass or ceramic or carbon spheres (or a mix thereof) sprayed into a uncured or wet resin material which is formed into a layer and after curing of the resin layer, it is abraded, sand or grit blasted so as to rupture the outermost layer of spheres or voids to provide a plurality of anchor sites undercuts or nooks and crannies. A thermally sprayed metal, such as copper, becomes embedded into the undercuts, nooks and crannies, such that the bond or adherent strength is greatly improved. This micronsized glass, ceramic carbon spheres and/or pores greatly increases the bond strength by providing better undercuts in the surface to be sprayed by molten metal and provide the capability of depositing thicker layers without jeopardizing the bond.
