Abstract:
A plasma spray system including a turntable subsystem operable to position a multiple of work pieces on a respective multiple of workpiece mounts; a plasma spray subsystem operable to plasma spray the multiple of work pieces on said turntable subsystem; and an overspray wash subsystem operable to wash the multiple of work pieces on said turntable subsystem subsequent to plasma spray of the multiple of work pieces.
Abstract:
A method and apparatus for microplasma spray coating a portion of a turbine vane without masking any portions thereof. The apparatus includes a microplasma gun with an anode, cathode, and an arc generator for generating an electric arc between the anode and cathode. An arc gas emitter injects gas through the electric arc. The electric arc is operable for ionizing the gas to create a plasma gas stream. A powder injector injects powdered material into a plasma stream. A localized area of the turbine vane is coated with the powdered material without having to mask the turbine vane.
Abstract:
An article such as a heat shield panel includes a substrate and a multi-layered coating supported on the substrate. The multi-layered coating can include alternating layers of different ceramic material compositions having individual thicknesses of less than 25 micrometers.

Abstract:
A method of applying a wear-resistant coating comprises mixing about 75% to about 85% by weight chromium carbide and about 15% to about 25% by weight nickel chromium to form a chromium carbide-nickel chromium mixture, and simultaneously heating the chromium carbide-nickel chromium mixture to about 1371 degrees Celsius to about 2204 degrees Celsius and applying the chromium carbide-nickel chromium mixture at a velocity in a range of about 305 meters feet per second to about 915 meters per second by high velocity oxygen fuel (HVOF) spraying.
