Patent number: 8563890Abstract: 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.Type: GrantFiled: December 8, 2012Date of Patent: October 22, 2013Assignee: United Technologies CorporationInventors: Paul Zajchowski, Donn R. Blankenship, Gary C. Shubert, Robert L. Memmen
