摘要： A thin electrical insulating coating and method for application is provided for a copper surface. The electrical insulating coating includes a bond coat layer of titanium, nickel, or NiCrAlY forming a metallurgical bond with the copper surface and an insulating layer of alumina or tantala applied to the bond coat layer. An insulating layer does not firmly adhere to copper under harsh environmental conditions such as an electroslag refining process when applied directly to the copper. However, when bond coat layer is applied between the copper and the insulating layer, it forms a strong bond adhering bond for the harsh environment.

摘要： An apparatus for viewing the atomization of liquid metal is disclosed. A nozzle for atomizing liquid metal having a cylindrical plenum, and a melt guide tube extending axially therethrough to a melt exit orifice. The plenum defines an inner chamber coupled with an atomizing gas orifice spaced from the exit orifice and configured to provide an annular jet of atomizing gas converging in an atomizing zone extending below the exit orifice The plenum having an inner sidewall and an outer sidewall defining the inner chamber therebetween. The inner sidewall extends below the exit orifice so that the inner sidewall is spaced from the atomizing zone. A cylindrical sleeve extends through the outer sidewall to a first end in the inner chamber. A camera mounted in the sleeve has a field of view extending from the first end. A transparent window is mounted to seal the first end. The sleeve is positioned so the field of view extends through the atomization zone. A porthole extends through the inner sidewall along the field of view to provide a view of the atomization zone to the camera, and for a gas flow therefrom.

摘要： A method of reducing "fall back" contamination caused by high intensity heating of metals is taught. Splatter, vapor droplets and particulate matter resulting from the high intensity heating is repelled to avoid return to the melt. An electric field is established above the heating zone to repel the vapor droplets and particles from at least one charged electrode disposed above the surface where high intensity heat is applied to a metal surface.

摘要： A refrigerator evaporator is formed in a spread serpentine configuration having a plurality of straight tube segments and a plurality of bent tube segments where each one of the straight tube segments is joined at an acute angle to at least one other straight tube segment. The straight tube segments are arranged in a number of planar rows which are adjacent and parallel to one another. Approximately 25-50 percent of the cross-sectional area of the evaporator is not occupied by tubing or any attached fins. A cross flow blower disposed at one end of the evaporator draws air longitudinally over the evaporator.

摘要： A nozzle for atomizing molten metal to provide a powder having improved yield of fine particles is disclosed. The nozzle is comprised of a gas plenum, a melt delivery tube, and an annular inner wall means within the gas plenum for delivering atomizing gas to the exit orifice of the melt delivery tube. The exit orifice of the melt delivery tube has a ratio of inside diameter to outside diameter that provides a reduced flow of liquid through the tube during atomization.

摘要： The introduction of spray formed metals into critical applications in the aircraft engine and power generation industries has been hampered by the possibility of erosion of oxide particles from a crucible lining or pouring nozzle in conventional spray forming equipment. These oxide particles may become inclusions that limit low-cycle fatigue life of parts. Use of a cold-walled induction guide (CIG) with an electrical insulation layer between copper CIG elements and the liquid metal offers a means of delivering ceramic-free alloys to a spray system with improved efficiency. CIG design options facilitated by a new oven-brazed fabrication technique resolve induction coil environmental isolation issues, correct thermal strain tolerance problems, facilitate dual frequency induction designs, allow improved electrical coupling efficiency and thermal efficiency, result in improved melt flow initiation, and facilitate disassembly without damage from the solidified melt.
