    摘要： A method for forming a squirrel cage rotor includes stacking a plurality of coated laminates to form a stacked laminate core preform. The stacked laminate core preform defines a plurality of open cavities. Each coated laminate of the plurality of coated laminates includes a laminate coated with a precursor layer. The precursor layer includes a binder and glass particles. The method further includes firing the stacked laminate core preform at a temperature above the softening point of the glass particles to form a low porosity rotor core. The method further includes casting a conductive material into the plurality of open cavities formed in the rotor core to define a conductive squirrel cage structure in the low porosity rotor core.

    摘要： Methods for forming sintered-bonded high temperature coatings over ceramic turbomachine components are provided, as are ceramic turbomachine components having such high temperature coatings formed thereover. In one embodiment, the method includes the step or process of removing a surface oxide layer from the ceramic component body of a turbomachine component to expose a treated surface of the ceramic component body. A first layer of coating precursor material, which has a solids content composed predominately of at least one rare earth silicate by weight percentage, is applied to the treated surface. The first layer of the coating precursor material is then heat treated to sinter the solids content and form a first sintered coating layer bonded to the treated surface. The steps of applying and sintering the coating precursor may be repeated, as desired, to build a sintered coating body to a desired thickness over the ceramic component body.

    摘要： Methods for fabricating wires insulated by low porosity glass coatings are provided, as are high temperature electromagnetic (EM) devices containing such wires. In embodiments, a method for fabricating a high temperature EM device includes applying a glass coating precursor material onto a wire. The glass coating precursor material contains a first plurality of glass particles having an initial softening point. after application onto the wire, the glass coating precursor material is heat treated under process conditions producing a crystallized intermediary glass coating having a modified softening point exceeding the initial softening point. The crystallized intermediary glass coating is then infiltrated with a filler glass precursor material containing a second plurality of glass particles. After infiltration, the filler glass precursor material is heat treated to consolidate the second plurality of glass particles into the crystallized intermediary glass coating and thereby yield a low porosity glass coating adhered to the wire.

    摘要： Methods for depositing wear resistant NiW plating systems on metallic components are provided. In various embodiments, the method includes the step or process of preparing a NiW plating bath containing a particle suspension. The NiW plating bath is prepared by introducing wear resistant particles into the NiW plating path and adding at least one charged surfactant. The first type of wear resistant particles and the first charged surfactant may be contacted when introduced into the NiW plating bath or prior to introduction into the NiW plating bath. The at least one charged surfactant binds with the wear resistant particles to form a particle-surfactant complex. The wear resistant NiW plating system is then electrodeposited onto a surface of a component at least partially submerged in the NiW plating bath. The resulting wear resistant NiW plating system comprised of a NiW matrix in which the wear resistant particles are embedded.
