  • Patent number: 11420257
    Abstract: An apparatus for efficiently preparing spherical metal powder for 3D printing includes a housing, a crucible and a powder collection area arranged in the housing, wherein a turnplate arranged in the collection area is an inlaid structure. A material having a poor thermal conductivity is selected as the base of the turnplate, and a metal material having a wetting angle less than 90° with respect to droplets is selected and embedded into the base to serve as an atomization plane of the turnplate. An air hole is disposed in the turnplate. The spherical metal powder for 3D printing combines electromagnetic force breaking capillary jet flow and centrifugal atomization, which breaks through the traditional metal split mode, and makes the molten metal in a fibrous splitting.

    Abstract: A process for repairing a damaged annular region of an anode configured to emit x-rays includes the step of machining the damaged annular region made of an initial target coating to a depth smaller than a thickness of the coating so as to leave behind a residual annular layer. An intermediate layer is then deposited on the residual annular layer. A repairing layer is then deposited on the intermediate layer. A heat treatment is then performed using an anneal which causes, by interdiffusion and formation of a solid solution, the material of the intermediate layer and the material of the residual annular layer to diffuse into each other and further cause the material of the intermediate layer and the material of the repairing layer diffuse into each other. As a result of this anneal the intermediate layer disappears.

  • Patent number: 10086426
    Abstract: In a method for producing a hot strip of steel with material properties that are adjustable over the strip cross-section, a steel melt is fed onto a revolving casting belt of a horizontal strip casting facility and solidifies to form a pre-strip having a thickness between 6 and 20 mm, and the pre-strip is subjected to a hot rolling process after complete solidification. A gas jet or plasma jet composed of metallic and/or non-metallic elements that affect the material properties of the hot strip influences the steel melt that is still liquid and/or just about to start to solidify. The concentration of the elements introduced into the melt by the gas jet or plasma jet and diffusing into the melt is adjusted across the strip thickness and strip width by changing the influencing kinetic energy of the gas jet or plasma jet, the partial gas pressure and/or the applied temperature.

  • Patent number: 10005129
    Abstract: This invention relates to a method of forming sections of seamless titanium or titanium alloy pipe. The method involves providing a substrate for forming pipe and a sleeve of a section of pipe on the substrate. The pipe section has an end from which the substrate projects. The pipe is formed by spraying particles of titanium or titanium alloy generally parallel to a longitudinal axis of the substrate to impact a face of the end and to cause particles to bond to and to accumulate on the pipe end to form pipe. The method further involves moving formed pipe longitudinally relative to the substrate to remove formed pipe from the pipe-forming substrate and continuing to spray titanium or titanium alloy particles onto the end face to cause further pipe to form continuously and integrally with the formed pipe. This enables a seamless titanium or titanium alloy pipe to be formed of any desired length.

    Abstract: A radiation source for generating EUV radiation includes a laser configured to fire laser pulses at a target area to which is supplied a stream of fuel droplets, which may be tin droplets that emit EUV radiation when excited by the laser beam. The EUV radiation is collected by a collector. The tin droplets may be pre-conditioned by a laser pre-pulse before the main laser pulse to change the shape of the droplets so that the droplets are in an optimum condition for receiving the main laser pulse. Embodiments of the invention take into account the effect of the vaporization of one fuel droplet on succeeding droplets and allow the timing of the main and/or pre-pulse to be adjusted to take into account any delay in arrival of the subsequent droplet or oscillations in the shape of the subsequent droplet which may be caused by vaporization of the preceding droplet.

  • Patent number: 8746027
    Abstract: The present disclosure provides a multi-layer tool piece coating. For example, the tool piece may be a mold or die used for forming ultra high strength steel sheet. The multi-layer mold coating may include a CrN or Ti(C)N junction layer, a first TiAlN/CrN nano multilayer, and a second TiAlCN/CrCN nano multilayer. The CrN or Ti(C)N junction layer may be coated on a base material of the tool piece (e.g., a mold) for forming the steel sheet. The first TiAlN/CrN nano multilayer may be coated on the CrN or Ti(C)N junction layer as an intermediate layer. The second TiAlCN/CrCN nano multilayer may be coated on the first TiAlN/CrN nano multilayer as an outermost surface functional layer, and may include carbon (C) of about 1 at. % to about 30 at. % for high temperature and low friction.

  • Publication number: 20130292081
    Abstract: A system for forming a soft magnetic bulk material of a predetermined shape from a magnetic material and a source of insulating material. The systems has a heating device; a deposition device; a support configured to support the soft magnetic bulk material of the predetermined shape; and a mask configured as a negative of at least a portion of the predetermined shape. The heating device heats the magnetic material to form particles having a softened state and wherein the deposition device deposits successive layers of particles of the magnetic material in the softened state on the support with the mask located between the deposition device and the support. The mask is indexed to a position relative to the support upon deposition of the successive layers. The mask selectively blocks the successive layers of particles of the magnetic material in the softened state from being deposited on the support forming the soft magnetic bulk material of a predetermined shape on the support.

The total content of the Ca and the Y is equal to or greater than 0.1% but less than 2.5% of the total weight of the magnesium alloy. The Mg alloy forms a dense composite oxide layer that acts as a protective film. Thus the Mg alloy has very excellent oxidation resistance and ignition resistance, can be melted, cast and machined in the air or a common inert atmosphere (Ar or N2), and can reduce the spontaneous ignition of chips that are accumulated during the process of machining.

  • Patent number: 8444777
    Abstract: An object of the present invention is to provide an Al—Zn—Mg—Cu 7000-series Al alloy having high ductility as well as having high strength. For attaining this purpose, an Al alloy having a structure in which an inclusion is not included is produced by reducing an amount of oxygen contained in an Al alloy that is obtained by solidifying a preform resulting from rapid solidification by preferably spray forming a molten metal of an Al—Zn—Mg—Cu 7000-series Al alloy with an inert gas. This Al alloy has, as mechanical properties at an ordinary temperature, a tensile strength of 600 MPa or more, and an elongation of 15% or more when the tensile strength is from 600 MPa or more and less than 800 MPa or an elongation of 10% or more when the tensile strength is 800 MPa or more, and is excellent in cold workability such as rollability.
