Abstract:
A method of atomization of metals which melt at high temperatures is provided. The atomization is carried out in an atomization zone at the lower end of a melt delivery tube. Melt is delivered to the zone through the tube. Atomizing gas is delivered to the melt emerging from the lower end of the melt delivery tube by impinging the gas inwardly against the outer tapered end of the melt delivery tube. The tube's outer surface is formed with a concavity so that the incident atomizing gas is deflected into contact with the emerging melt stream.
Abstract:
A method for generating prime powder from a material having a high melting point and apparatus for generating the powder is taught. The apparatus includes a melt delivery tube. The melt of the high melting material is introduced into the tube and exits from the tube into an atomization zone. Gas is delivered to the zone at high pressure as a stream to atomize the melt. Pursuant to the present invention, the atomizing gas is directed against the lower end of the melt delivery tube and it is deflected from the melt delivery tube into contact with the descending high temperature melt. A concave surface is provided on the end of the melt delivery tube to deflect the gas along the tube surface to minimize Eddy currents and provide better control of the atomization process.
Abstract:
In various embodiments, eroded sputtering targets are partially refurbished by spray-depositing particles of target material to at least partially fill certain regions (e.g., regions of deepest erosion) without spray-deposition within other eroded regions (e.g., regions of less erosion). The partially refurbished sputtering targets may be sputtered after the partial refurbishment without substantive changes in sputtering properties (e.g., sputtering rate) and/or properties of the sputtered films.

Abstract:
In various embodiments, tubular sputtering targets comprising molybdenum are provided and sputtered to produce thin films comprising molybdenum. The sputtering targets may be formed by forming a tubular billet having an inner diameter IDI and an outer diameter ODI, the formation comprising pressing molybdenum powder in a mold and sintering the pressed molybdenum powder, working the tubular billet to form a worked billet having an outer diameter ODf smaller than ODI, and heat treating the worked billet. The sputtering targets may have a substantially uniform texture of (a) a 110 orientation parallel to a longitudinal direction and (b) a 111 orientation parallel to a radial direction.
Abstract:
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.
Abstract:
In various embodiments, planar sputtering targets are produced by forming a billet at least by pressing molybdenum powder in a mold and sintering the pressed powder, working the billet to form a worked billet, heat treating the worked billet, working the worked billet to form a final billet, and heat treating the final billet.
