Overlay/Bond Coatings that Resist Hot Corrosion in Navy Gas Turbines
AI Overview
This RFP seeks advanced overlay/bond coatings that resist hot corrosion in Navy marine gas turbine engines. The improved coatings must eliminate salt and sulfur-induced degradation in turbine blades to extend engine service life and reduce maintenance removal cycles.
This summary is AI-generated from the official solicitation.
Key Details
Official Description
Marine gas turbine engines serve as primary and auxiliary power sources for several current classes of ships in the U.S. Navy. It is desirable for marine gas turbine engines to have a mean time between removals of 20,000 hours. While some engines have approached this goal, others have fallen significantly short. The main reason for this shortfall is various forms of hot corrosion (Type I and Type II) damage in the hot section turbine hardware due to intrusion of salts from the marine air and/or ...

Overlay/Bond Coatings that Resist Hot Corrosion in Navy Gas Turbines
Added answer to Q1 clarifying: Phase I should focus on understanding corrosion mechanism at 600°C (solid-state degradation) rather than providing coating samples; no specific alloy required; coating must minimize interdiffusion with substrate; approach must address environmental conditions and potential substrates based on provided references.
