  • Underplatform coating tool
    Patent number: 6391115
    Abstract: The present invention relates to an improved tool for holding at least one turbine blade having a platform during the application of a coating to underplatform areas of the at least one turbine blade. The tool includes at least one fixture for holding the at least one turbine bladed during the coating application. The at least one fixture has a base receptacle for receiving the at least one turbine blade and a cover for the base receptacle. Each of the base receptacle and the cover has an opening which corresponds in shape to each of the underplatform areas to be coated.
