| abstract | 1,199,377. Powder metallurgy. Coating with metals. MONSANTO CO. Dec. 24, 1968 [March 26, 1968], No.61304/68. Addition to 1, 199, 376. Headings C7D and C7F. A composite metal article reinforced with aligned inorganic fibres is formed by extruding a dispersion of metal coated inorganic fibres and powdered metal in a film forming organic colloid medium into a coagulating bath for the medium, burning off the organic constituents of the coagulated product and hot pressing the product so obtained. The extruded material may be formed into a lay up, either by using its inherent stickiness or by using an adhesive such as polyvinyl alcohol, starch, carboxymethyl-cellulose or gum tragacanth before the carbonaceous material is burnt off. The reinforcing fibre may be fibres of any refractory inorganic material of length 5-7, 500 microns and aspect ratio 5-1000 and may be a carbide of tantalum, niobium, hafnium, zirconium, tungsten, titanium, vanadium, aluminium, molybdenum, boron, beryllium, chromium, uranium, thorium or silicon, an oxide of magnesium, cerium, gadolinium and hafnium, a silicide of tantalum, tungsten, niobium or molybdenum, a boride of lanthanum, zirconium, tungsten, niobium, titanium or a nitride of silicon, vanadium, tantalum or niobium. Mixtures of different fibres may be used. The fibres are coated with a thin film of metal or metal alloy by for example, electro-plating, dipping into a molten bath, spray deposition, vapour deposition or gas plating from readily decomposible metal compounds. Examples of suitable coating metals are silver, gold, nickel, chromium, cobalt, titanium and copper. The metal powder which forms the matrix may be the same as the coating metal or may include any of the elements Al, Sb, As, Be, Bi, Cd, Ca, Ce, Cr, Co, Nb, Cu, Dy, Er, Gd, Au, Hf, Ho, In, Ir, Fe, La, Pb, Li, Mg, Mn, Mo, Nd, Ni, Os, Pd, Pt, Pr, Re, Rh, Ru, Sm, Se, Ag, Sr, Ta, Tc, Te, Tb, Th, Tm, Sn, Ti, W, V, Y, Yb, Zn or Zr. The carbonaceous material is preferably burned out by heating first to a temperature below 400 C. and then heating to a temperature between 500 C. and that at which the metal powder is affected. After removal of carbonaceous material, the article may be cold pressed before it is hot pressed. |
