A method includes forming one or more cores, wherein each of the one or more cores has a cross section corresponding to a conductor to be subsequently formed, forming an insulator around the one or more cores, removing the one or more cores to expose one or more recesses within the insulator, and forming one or more conductors in at least one of the one or more recesses of the insulator such that the cross sections of the one or more conductors conform to an interior surface of the one or more recesses in the insulator.

A curable composition for bonding windings or core laminates in an electrical machine is presented. The curable composition includes: (A) about 10 weight percent to about 25 weight percent of a polyfunctional cyanate ester; (B) about 35 weight percent to about 65 weight percent of a first difunctional cyanate ester, or a prepolymer thereof; (C) about 15 weight percent to about 40 weight percent of a second difunctional cyanate ester, or a prepolymer thereof. An associated method is also presented.

A gradient coil comprises a curved conductor, which is tubular and has a general spiral shape. The curved conductor is formed by a process comprising depositing at least one non-conductive material layer by layer to form a substrate, and coating at least a portion of a surface of the substrate with a conductive material. The substrate has a shape matching with the general spiral shape of the curved conductor. Embodiments of the present disclosure further refer to a method for manufacturing the gradient coil.

A curable composition for an electrical machine is presented. The curable composition includes: (A) about 10 weight percent to about 30 weight percent of a polyfunctional cyanate ester; (B) about 25 weight percent to about 60 weight percent of a first difunctional cyanate ester, or a prepolymer thereof; (C) about 10 weight percent to about 30 weight percent of a second difunctional cyanate ester, or a prepolymer thereof, and (D) about 5 weight percent to about 25 weight percent of a thermally conductive filler comprising boron nitride. An associated method is also presented.

A method of making a composite magnet wire includes mixing alumina nano particles with a polyimide polymer to form a polyimide mixture, the alumina nano particles having a surface treatment applied to outer surfaces of the alumina nano particles, the surface treatment including a phenyl-silane; coating a wire with the polyimide mixture by passing the wire through a coating die; heating the coated wire; cooling the coated wire; passing the coated wire through an annealing oven at a temperature of about 425&#xb0; C. to about 475&#xb0; C. at a speed of about 15 to about 30 feet per minute to anneal the coated wire; cooling the annealed coating wire; spooling the coated wire onto a metal spool; heating the spooled wire at about 300&#xb0; C. to about 400&#xb0; C. for about 20 to about 40 minutes; and cooling the heated spooled wire.

A composite magnet wire includes, in an exemplary embodiment, a metal wire and a coating applied to an outer surface of the wire. The coating includes a polyimide polymer and a plurality of alumina nano particles dispersed in the polyimide polymer. The alumina nano particles have a surface treatment applied to outer surfaces of the alumina nano particles, where the surface treatment includes a phenyl-silane. The composite magnet wire has a thermal degradation temperature index of at least 300&#xb0; C. as calculated in accordance with ASTM E1641 or D2307.

A composite article comprises a substrate having at least a substrate surface and a graded-composition coating disposed on a substrate surface. The composition of the coating material varies substantially continuously across its thickness. The coating reduces the transmission rates of oxygen, water vapor, and other chemical species through the substrate such that the composite article can be used effectively as a diffusion barrier to protect chemically sensitive devices or materials. An organic light-emitting device incorporates such a composite article to provide an extended life thereto.

The present invention is directed to a salt optic provided with a multilayer coating in order to improve upon the moisture resistance of a salt optic, when compared to the moisture resistance of an uncoated salt optic. In one aspect, the present invention is comprised of a coated salt optic having at least a first coating layer and a second coating layer, the first coating layer being surface-smoothing layer and adhesion layer, and the second coating layer being a moisture barrier layer.

A method of forming a hydrogenated amorphous germanium carbon (&#x3b1;-GeC:H) film on a surface of an infrared (IR) transmissive material such as a chalcogenide is provided. The method includes positioning an IR transmissive material in a reactor chamber of a parallel plate plasma reactor and thereafter depositing a hydrogenated amorphous germanium carbon (&#x3b1;-GeC:H) film on a surface of the IR transmissive material. The depositing is performed at a substrate temperature of about 130&#xb0; C. or less and in the presence of a plasma which is derived from a gas mixture including a source of germanium, an inert gas, and optionally hydrogen. Optical transmissive components, such as IR sensors and windows, that have improved abrasion-resistance are also provided.
