Determination of the Ductile to Brittle Transition Temperature of Platinum-Aluminide Gas Turbine Blade Coatings

Abstract

A strain-to-failure method was employed with Naval Postgraduate School tensile testing equipment to determine the ductile to brittle transition temperature (DBTT) of five basic platinum-aluminide gas turbine blade coatings on a nickel-base superalloy (IN738). THe results of these tests were compared to similarly formed nickel-aluminide coatings without platinum and aluminum content and structure on coating ductility. Keyword: Acoustic signatures.
