    摘要: A method for repairing a workpiece includes the steps of providing an unstripped, coated workpiece comprising a surface having a localized damage site; masking the workpiece about the localized damage site; generating a microplasma stream; and applying a first powdered material to the localized damage site using the microplasma stream; and applying a second powdered material to the workpiece surface using the microplasma stream. Another method for repairing a workpiece includes the steps of providing an unstripped, coated workpiece comprising a surface having a localized damage site; generating a microplasma stream; applying without a maskant a powdered metal alloy to the damage site using the microplasma stream; and dimensionally restoring the workpiece.

    摘要: A method and apparatus for microplasma spray coating a portion of a substrate, such as a gas turbine compressor blade, 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 inert 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 compressor blade is coated with the powdered material without having to mask the compressor blade.

    摘要: A method for repairing a workpiece using microplasma includes the steps of generating a microplasma stream having a width of about 0.5 millimeters to about 5 millimeters; applying the microplasma stream to a workpiece; and coating a portion of the workpiece with the microplasma stream without masking the workpiece. One or more quantities of powdered materials entrained in the microplasma stream may be applied to the workpiece without masking the workpiece after applying the first layer.
