Abstract
Fine metal filters are formed by rolling into a thin layer an alloy composed of a precious or semi-precious metal and a low boiling-point metal, for example, zinc, and heating the layer in a vacuum to the vaporisation temperature of the low boiling-point metal but below the melting-point of the alloy. The low boiling-point metal is evaporated, leaving a filter body of fine porous structure.ALSO:A method of making a porous metal body, comprises producing an alloy of one or more solid metals of low boiling-point and one or more metals of higher boiling-point and evaporating the low boiling-point metal or metals to leave a porous body. The alloy may be shaped to any desired form prior to evaporation; for example, relatively thin alloy layers may be formed by rolling. The alloy may be rolled to a layer not greater than 50 thousandths of an inch thick and then heated to an elevated temperature at which the low boiling-point metal has a substantial vapour pressure. The temperature is maintained till any desired proportion of the low boiling-point metal has been evaporated. The temperature may be raised as the composition of the alloy changes, and evaporation may be carried out in vacuum or partial vacuum. The resulting porous body may be impregnated with a metallic or non-metallic material, for instance a lubricant or molten lead. The Specification refers to the production of bearings by evaporating the low boiling-point metal from an overlay metal comprising a ferrous metal backing and a facing layer of an alloy of one or more of copper, silver, gold, aluminium, platinum and palladium, with zinc or cadmium (see Group XXXIV); the production of electrolytic condenser foil from an alloy of aluminium and zinc or cadmium in foil form (see Group XXXVI), and the production of fine metal filters from thin layers of alloys of precious or semi-precious metals with low boiling-point metals (see Group I).
