Generic, Low Cost, Aluminide Hot Section Coating for Gas Turbine Engines

Project successfully produces data supporting generic nature of diffused aluminide coatings for gas turbine hot section components. The Department of Defense will prepare military specifications for use in competitive procurement of such coatings. The second objective of the project, to develop a low cost, generic coating procedure indicates cost savings of 50 to 80% and is basis for DoD process specification. Paper includes arguments and supporting data. A unique aspect of the project is that it was funded by commercial interests in lieu of the taxpayers.
