Abstract: Methods for coating a fiber are provided. The method can include unwinding a silicon carbide-containing fibrous material from a bobbin rotatably mounted around an axle and forming a boron nitride coating onto the silicon carbide-containing fibrous material. The bobbin is moved along the axial direction such that the silicon carbide-containing fibrous material defines an unwind angle with the axial direction, with the unwind angle being maintained between about 80° to about 100°.

Abstract: A multi-loop controller component for an electric discharge machining (EDM) system includes a plurality of power loop circuits coupled to an output of a power supply of the EDM system and configured to receive DC electric power from the power supply. Each power loop circuitis electrically-isolated from other power loop circuits. The multi-loop controller component also includes a plurality of transistors. Each transistor is coupled to a respective power loop circuit and is configured to switch between an ON state and an OFF state to generate a pulse of the DC electric power through the respective power loop circuit. In addition, the multi-loop controller component has a drive controller coupled to the plurality of transistors. The drive controller is configured to transmit at least one control signal to at least one of the transistors to facilitate switching the transistor between the ON state and the OFF state.

Abstract: A method of casting a low alloy steel using a mold is disclosed. The method includes receiving the mold having a foam pattern disposed within a sand casing. The received foam pattern is coated with a permeable refractory coating and is disposed between compacted sand and the sand casing. The method further includes pouring a molten metal comprising a low alloy steel having a carbon content in a range from about 0.1 to about 0.4 percent into the mold so as to vaporize the foam pattern and remove gasification products through the permeable refractory coating, to form a low alloy steel casting. Further, the method includes removing the low alloy steel casting from the mold.
