  • Method for fluent mass surface texturing a turbine vane
    Patent number: 5090870
    Abstract: An apparatus and method for providing vanes with a surface texture of less than 10.times.10.sup.-6 inches rms. The method employs a fluent mass having a particulate size less than 1.5 inches and abrasive materials in a centrifugal barrel to achieve a surface texture between 11-27.times.10.sup.-6 inches rms. A refinement cut employs a finer abrasive and a cycle time of less than 30 minutes to provide a burnished surface texture of between 5-8.times.10.sup.-6 inches rms. A final coloring cycle, employing only a coloring compound, is employed to provide a highly reflective surface texture between approximately 4-7.times.10.sup.-6 inches rms.
