Abstract
1,194,600. Sintered tungsten or molybdenum base alloys. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. Oct.25, 1968 [Nov.3, 1967], No.50181/67. Headings C7A, C7D and C7U. A metal body consisting mainly of W and/or Mo, is composed of, or has at least a surface layer composed of, an alloy comprising:- at least # Al, Be, Ce, Cr, Hf, # 5-20% in total one of # Mg, Th, Ti, U, Zr, # 5-20% in total, at least # Co, Ir, Ni, Os, # 0À01-10% in total, one of #Pd, Pt, Rh, Ru # and at # As, Bi, Ge, P, S, # least # 0À001-10% in total, of # Sb, Se, Si, Sn, Te the balance being W and/or Mo in any relative proportions. The relative proportions of elements from the three groups are so chosen that the body can be made resistant to high temperature oxidation by heating in air or moist hydrogen to form an adherent protective oxide layer. A preferred alloy comprises Cr 5-20%, Pd, 0À5-10% and As 0À01-1%, the balance being W and/or Mo. If the body is to be of one basic composition it may be made by arc melting and casting or preferably by mixing the constituents, some of which may be present as master alloys, in powder form, preferably with a particle size smaller than 5 microns, isostatically pressing (e.g. in glycerol) and then sintering. If the sintering temperature is high enough to form the required oxide layer, it may be performed in air or moist hydrogen. If this is not so the sintered compact must be heat treated in air or moist hydrogen as is the case for the cast bodies. For a body which only has the surface layer of the appropriate composition, a body of a W and/or Mo based alloy, optionally containing Re, Ta, ThO 2 and potassium silicate, is coated with the elements in which it is deficient (e.g. by vapour deposition or electro-plating) and is subjected to a diffusing heat treatment prior to the oxidizing heat treatment in air or moist hydrogen. Some compositions do not require a separate heat treatment as the oxide layer is formed when the article is used.
