COATINGS FOR GAS TURBINE COMPONENTS |
摘要 |
A gas turbine component for use in a gas turbine engine includes a substrate and a non-aluminide protective coating with a platinum-group metal. The platinum-group metal resides in a gamma-prime phase of the underlying material. The platinum-group metal can impart the protective coating with superior corrosion-resistance, while the absence of aluminide in the protective coating facilitates use of the protective coating at high-stress and/or high-fatigue portions of the component. The protective coating optionally includes chromide and can also be combined with aluminide at select portions of the component.
