Abstract

A metal body based on W and/or Mo includes at least in the surface layer a minor proportion e.g. 5-15% by weight of a more easily oxidizable metal e.g. Cr, Th, Ti, Hf, Zr, U, Mg, Ce, Al and Be and a minor proportion e.g. 0.01-10%, of Co, Ni, Ru, Rh, Pd, or Pt and is heat treated in an oxidizing atmosphere to form an adherent protective coating consisting of or including an oxygen containing compound of the preferentially oxidizable metal. The body which may also contain up to 20% of Re or Ta and 1-2% of thoria or potassium silicate is formed by arc melting and casting or by pressing and sintering the constituents. Alternatively a W or Mo based sintered or cast body may be coated with the preferentially oxidizable metal e.g. Cr electrolytically or by vapour deposition and then heated to cause a diffused surface alloy. The preferred body contains 5-10% Cr, 1-5% Pd and the balance W and the oxygen containing layer may be formed during the normal conditions of use of the body or by heating in air or moist hydrogen prior to use. The oxidizing step may also be carried out during the sintering step e.g. at 1300 DEG -1500 DEG C. for W-Cr alloys or 1400 DEG -1450 DEG C. for W-Cr-Pd alloys or preferably in two stages.
