METHOD AND SYSTEM FOR ENHANCING HEAT TRANSFER OF TURBINE ENGINE COMPONENTS

摘要

A method and system for enhancing the heat transfer of turbine engine components is disclosed that includes applying a metallic coating having a high thermal conductivity to the cold side of a turbine component to enhance heat transfer away from the component. The metallic coating may be roughened to improve heat transfer. The metal coating may be a Ni—Al bond coating having an aluminum content greater than about 50 weight percent.
