    摘要： A multi-station flexographic printing system includes a plurality of flexographic printing stations. Each flexographic printing station includes a flexo master. Each flexo master comprises a Fresnel zone pattern in a unique position. A method of aligning a plurality of flexographic printing stations includes printing a Fresnel zone pattern on a substrate in a unique position for each flexographic printing station. Light is directed through the Fresnel zone patterns on the substrate. The light focused by the Fresnel zone patterns is captured with a sensor device.

    摘要： The present invention is directed to a process for the preparation of a metal powder having a purity at least as high as the starting powder and having an oxygen content of 10 ppm or less comprising heating said metal powder containing oxygen in the form of an oxide, with the total oxygen content being from 50 to 3000 ppmf in an inert atmosphere at a pressure of from 1 bar to 10−7 to a temperature at which the oxide of the metal powder becomes thermodynamically unstable and removing the resulting oxygen via volatilization. The metal powder is preferably selected from the group consisting of tantalum, niobium, molybdenum, hafnium, zirconium, titanium, vanadium, rhenium and tungsten. The invention also relates to the powders produced by the process and the use of such powders in a cold spray process.

    摘要： Disclosed is a method of applying coatings to surfaces, wherein a gas flow forms a gas-powder mixture with a powder of a material selected from the group consisting of niobium, tantalum, tungsten, molybdenum, titanium, zirconium, nickel, cobalt, iron, chromium, aluminum, silver, copper, mixtures of at least two thereof or their alloys with at least two thereof or with other metals, the powder has a particle size of from 0.5 to 150 μm, an oxygen content of less than 500 ppm oxygen and a hydrogen content of less than 500 ppm, wherein a supersonic speed is imparted to the gas flow and the jet of supersonic speed is directed onto the surface of an object. The coatings prepared are used, for example, as corrosion protection coatings.

    摘要： A method for improved atomization of molten metal having a melting point above 1000.degree. C. is taught. The atomization is carried out in close coupled atomizer. The melt to be atomized is supplied from a reservoir where it is heated to a temperature slightly above the melting point. The molten metal from the reservoir is guided to the atomization zone by a ceramic melt guide tube. The atomization is accomplished with the aid of a shallow draft atomizing nozzle. The melt in the melt guide tube is heated with the aid of an induction coil which is disposed thereabout and between the reservoir and the shallow draft gas nozzle.
