    摘要： Articles transparent to infrared radiation and resistant to impact and wear are provided. In one embodiment the article comprises a substrate and a composite coating disposed over the substrate and extending from an interface with the substrate to an external surface. The coating and the substrate are capable of transmitting infrared radiation. The composite coating comprises a first phase and a second phase, where the second phase has a higher resistance to erosive wear than the first phase. The coating comprises a compositional gradient proceeding from a first composition at the interface of the coating with the substrate to a second composition at the external surface, the first composition comprising a higher concentration of the first phase than that of the second composition. The first phase has at least one property selected from the group consisting of a) a coefficient of thermal expansion (CTE) that is within about plus or minus 3 parts per million per degree centigrade of a CTE of the substrate, and b) an index of refraction that is within a range from as high as about 0.1 plus the index of refraction of the substrate to as low as about the square root of the index of refraction of the substrate.

    摘要： A porous carbon body is produced from a carbon felt with a low level of metal impurity by forming the body from a carbon felt with a low level of metal impurity, and infiltrating the body with silicon. In another aspect of the invention, an annealing furnace is treated with a halide-containing gas at elevated temperature to scavenge metal impurities. A porous carbon body is then infiltrated with silicon in the annealing furnace.

    摘要： In a method of coating a CMC fiber, the fiber is passed through a reaction zone along a path substantially parallel to a longitudinal axis of the zone, a flow of fiber coating reactant is passed though the reaction zone, at least a portion of the flow of reactant is disrupted from a path substantially parallel to the fiber path to create a mixing flow adjacent the fiber. A coating reactor includes a reactor chamber to accommodate a fiber passing along a path substantially parallel to a longitudinal axis of the chamber and a flow of fiber coating reactant. The reactor chamber further includes a flow disrupter located within the reactor chamber to disrupt at least a portion of the flow of reactant from a path substantially parallel to the fiber path to create a mixing flow adjacent the fiber.
