    摘要： The invention is a weld metal for welding of a titanium alloy member to a ferrous based alloy member as an intermediate transition zone between such members so as to overcome the metallurgical imcompatability of each such member, and which consists of a vanadium metal, titanium and iron and inconsequential amounts of brittle intermetallic compounds. The preferred weld metal is vanadium rich and contains no more than 50% combined weight of titanium and such a weld metal is produced in accordance with our invention by fusion welding, particularly capacitor discharge welding, which because of its inherent but heretofore unrecognized extremely fast quench or freeze rates will produce a fusion weld between these two metallurgically incompatible alloys which is free of brittle intermetallic compounds. It is also part of our invention that such a weld metal of the aforesaid composition will have independent use as a welding alloy, particularly when fabricated in sheet form.

    摘要： The disclosure relates to a method of bonding columbium to columbium wherein a brazing foil of titanium which has been coated with either a layer of copper or a layer of nickel or layers of copper and then nickel, preferably on both sides of the foil, is disposed between the columbium sheets or the like to be joined. The columbium are placed in intimate contact with opposite sides of the foil and heated to a temperature above the eutectic point of the eutectics of the metals of the foil and no higher than about 1750.degree. F. for about 90 minutes and then cooled to provide the desired bond.

    摘要： A method is disclosed for applying hard tungsten carbide particles to the surface of metal stabilizers used in the drilling of oil, gas, geothermal and water wells. The process consists of applying a soft, elastic metal powder to the surface of the substrate. Large tungsten carbide particles, which have also been coated with the soft powder, are placed on top of the layer of soft powder. The particles are then covered with additional soft powder, which powder is then fused to form a homogeneous, large tungsten carbide particle containing mixture bonded to the substrate. A hard matrix is applied and fused over the large tungsten carbide particle containing mixture. The large tungsten carbide particles, which have a low coefficient of expansion, are thereby contained in a soft elastic metal matrix which acts as an expansion and cushion material, while the hard matrix presents a less resilient, more wear resistant surface. This arrangement is advantageous because the coefficient of expansion of the hard matrix material is much higher than the coefficient of expansion of the carbide particles. The soft elastic matrix thereby cushions the carbide particles and prevents them from being crushed as the hard matrix expands and contracts in response to changing temperatures and conditions.
