Abstract
Abstract THE PROPERTIES OF ARTICLES FABRICATED FROM FOAMED METALS (SUCH AS FOAMED ALUMINUM) ARE ENHANCED BY COATING SURFACES THEREOF WITH PLASTIC MATERIALS, E.G., ACRYLONITRILE-BUTADIENE-STYRENE POLYMERS. FOR EXAMPLE, THE PLASTIC COATING IMPROVES THE PHYSICAL PROPERTIES, AND ENABLES THE ARTICLE TO BE JOINED TO ANOTHER FOAMED METAL ARTICLE, OR TO A METAL SHEET, WIRE, GLASS, ROCK, OR OTHER MATERIAL. THE ORGANIC COAT GIVES IMPROVED STRENGTH TO SUCH JOINT.
