摘要： A method and apparatus for producing AlN powder employing a vacuum chamber with a nozzle thereon having a hollow center crucible of graphite with a small feed hole in the bottom thereof. A device is provided for heating and melting aluminum in the crucible. A plasma gun connected to a source of argon and nitrogen is ignited below said feed hole, and melted aluminum moves into the plume of said plasma gun. The melted aluminum is atomized in the plume, and the droplets of aluminum are vaporized and react to the nitrogen in the plume, to create AlN which is collected in a collecting chamber.

摘要： An abrasion resistant coating is created by adding a ductile phase to a brittle matrix phase during spray coating where an Al—Cu—Fe quasicrystalline phase (brittle matrix) and an FeAl intermetallic (ductile phase) are combined. This composite coating produces a coating mostly of quasicrystal phase and an inter-splat layer of the FeAl phase to help reduce porosity and cracking within the coating. Coatings are prepared by plasma spraying unblended and blended quasicrystal and intermetallic powders. The blended powders contain 1, 5, 10 and 20 volume percent of the intermetallic powders. The unblended powders are either 100 volume percent quasicrystalline or 100 volume percent intermetallic; these unblended powders were studied for comparison to the others. Sufficient ductile phase should be added to the brittle matrix to transform abrasive wear mode from brittle fracture to plastic deformation, while at the same time the hardness of the composite should not be reduced below that of the original brittle phase material.
摘要翻译：通过在Al-Cu-Fe准结晶相（脆性基体）和FeAl金属间化合物（延性相））组合的喷涂期间向脆性基体相添加延性相，形成耐磨涂层。这种复合涂层主要产生了晶体相和FeAl相的夹层，以帮助减少涂层内的孔隙率和裂纹。涂料通过等离子喷涂未掺合和混合的准晶体和金属间粉末制备。混合粉末含有1,5,10和20体积％的金属间粉末。未共混的粉末是100体积％的准晶体或100体积％的金属间化合物; 研究了这些未掺杂的粉末与其他粉末的比较。应将脆性基体上的足够的韧性相加入，将磨损模式从脆性断裂转变为塑性变形，同时复合材料的硬度不应低于原始脆性相材料的硬度。

摘要： A tubular thermal sprayed melt containment component for transient containment of molten metal or alloy wherein the tubular member includes a thermal sprayed inner melt-contacting layer for contacting molten metal or alloy to be processed, a thermal sprayed heat-generating layer deposited on the inner layer, and an optional thermal sprayed outer thermal insulating layer. The thermal sprayed heat-generating layer is inductively heated as a susceptor of an induction field or electrical resistively heated by passing electrical current therethrough. The tubular thermal sprayed melt containment component can comprise an elongated melt pour tube of a gas atomization apparatus where the melt pour tube supplies molten material from a crucible to an underlying melt atomization nozzle.
