摘要： Surfaces of magnesium-base alloy workpieces may be mechanically worked and deformed to increase their resistance to corrosion, especially corrosion occurring in the presence of water or water and salt or other corrosive media. Workpiece surfaces that are to be thus protected are engaged in squeezing, sliding, and frictional contact with a suitable burnishing or other working tool that traverses the surface to compress and deform it and to refine the metallurgical grain structure. For example, the grain size is reduced in a surface layer that may extend to a depth of up to a few millimeters. And grain orientation is altered within that depth. The tool is not employed to intentionally remove material from the surface of the workpiece. The initial dimensioning of the workpiece may take into consideration the alteration of surfaces by the mechanical working process.

摘要： A method and apparatus for casting a molten metallic material in ingot form are provided wherein the molten metallic material is transported to the ingot mold and an upper surface temperature and temperature distribution of the molten metal pool in the casting mold are measured by an imaging radiometer which is disposed external to an inert gas filled chamber enclosing the ingot mold, and is disposed to view the ingot pool surface through a sight port. At least one plasma arc torch is employed to direct an arc at the ingot pool surface, the intensity of which is selectively modulated and the impingement of the arc is simultaneously selectively positioned in order to maintain a desired preselected mold pool surface temperature and temperature distribution thereby yielding a preselected metallurgical structure in the solidified ingot. The imaging radiometer may provide a video signal as an output, and may be connected to a video analyzer and video monitor which are used to provide an image of the surface temperature and temperature distribution, enabling an operator to control the plasma arc torch in performing the ingot casting method.

摘要： A method of hardening the surface of titanium and its alloys, and other structural metals which form hard carbides, by treating the surface thereof with a moving, discontinuous carbon arc.The metal surface to be hardened, and a carbon electrode are made opposite poles of an electric current source, and moved and/or rotated with respect to each other so that a multiplicity of discontinuous electric arcs are produced between the carbon electrode and the metal surface.Carbon particles transfer through the arc and alloy within craters of the instantly liquified and chilled substrate, producing a surface layer which, in the case of titanium, is hard and tough and adherent enough to form the working surface of abrasive cutting tools.The process improves the appearance and durability of consumer items and reduces friction and wear on machine parts.

摘要： Apparatus for improving properties of a solid material by providing shock waves therein. A laser oscillator 10a provides a plurality of pulses 112 of coherent radiation. The leading edge of each pulse is sharpened either by a metal foil 18 or by phase conjugation reflection means 18a, 18e including a stimulated Brillouin scattering cell 18d,18e and optionally a Faraday isolator 18b. Each pulse is directed onto an amplifier 123 comprising first and second laser amplifier rods 23a,23b in series. At least a major portion of the radiation 112 amplified by the first amplifier rod 23a is directed to the second amplifier rod 23b, where it is amplified and then directed to a surface of the solid material. Substantially uniform spatial amplitude is achieved in the radiation 112 in at least one of these ways: A pair of flashlamps 70,71 are included with each laser amplifier rod 23a,23b for pumping the rod; the axis of each flashlamp 70,71 and the axis of the first rod 23a are substantially parallel to each other and substantially in the same (first) plane; and a (second) plane containing the axis of the second rod 23b and the parallel axes of its associated flashlamps 70,71 is substantially perpendicular to the first plane; and/or the oscillator 10c provides a beam of unpolarized coherent radiation 12T in which the spatial amplitude pattern of each succeeding pulse is substantially a mirror image of the pattern in the pulse that preceded it, or is rotated about its axis by a predetermined smaller angle from the pattern in the pulse that preceded it.

摘要： A process for increasing the oxidation resistance and corrosion resistance of a component made of a dispersion strengthened superalloy by means of a surface treatment, the object of which in every case is to produce or retain a fine-grained surface zone (5) while the core zone (4) of the component in all circumstances is forced to form coarse grains during the final recrystallization annealing in the temperature range between the recrystallization temperature and the solidus temperature. A fine-grained surface zone (5) is produced by cold-working the surface zone (3, 5) by shot-peening, surface milling or pressing or by heating the surface zone (7) to a temperature about 100.degree. to 140.degree. C. below the recrystallization temperature by means of a laser (9) or an arc (10) while the core zone is kept at less than 900.degree. C., or by application of a 10 to 50 .mu.m thick nickel layer onto the surface followed by diffusion of the nickel into the surface zone (nickel-rich surface layer 14) of the component at a temperature below the recrystallization temperature. In each case, recrystallization annealing in order to establish coarse grains in the core zone (4) is finally carried out.
