Coating-Substrate Systems for Thermomechanically Durable Turbine Airfoils.

摘要

The specific goals of the proposed research have been threefold: (1) to establish a fundamental, mechanistic understanding of the degradation processes that occur in superalloy components with coatings during thermo-mechanical cycling; and (2) to use the experimental information to critically evaluate and further develop models for thermochemical and thermomechanical degradation of the multilayered systems and (3) to more quantitatively define the design space and guide the development of future multilayered systems for Naval applications.
