Abstract
Hard metal grains, or non-weldable grains coated with a layer of weldable metal are fixed to a metallic base by first spreading on the base a layer of welding material, then sprinkling on to the coated base the metal or metal-coated grains and finally sprinkling on the base a granulated heat-resistant substance such as sand and causing the welding material to melt, the said granulated substance serving to hold the metal or metal-coated grains in position during the melting operation and allow the escape of the gases resulting from the decomposition of the suspension liquid. By "welding material" is meant brazing or soldering material in suspension in a liquid such as lignite tar-oil, said material being reduced to an impalpable powder and mixed with pickling and oxidizing agents and fluxes, also in powder form. The granulated heat-resisting substance may be applied cold and the whole heated in a furnace, or it may be preheated, in which case it serves to melt the weldable material. Suitable metallic grains are stainless or hardened steel, or tungsten carbide; metal-coated grains include metallized diamond chips. The process may be applied to the manufacture of grinding tools such as pestles and mortars.
