Design of Resilient Salt-phobic and Corrosion Resistant Coatings for Marine Gas Turbines
Abstract
Project Abstract Approved for Public Release -This research will develop the science base necessary to design new coating materials, to reduce the accumulation of salt deposits on compressor components in the gas turbine engines following seawater ingestion. The c,entral hypothesis is that the implementation of hydrophobic coatings will reduce the rate of salt accumulation, extend the interval, between compressor washing, and ensure complete performance recovery after washing. Thus, the principal objective is to establish t,he science underpinning surface wetting characteristics to salt deposit adhesion and accumulation during water evaporation. The appr,oach uses new experimental techniques to systematically assess parameters related to coating composition and surface structure over, a range of operating conditions. This knowledge will then be applied to the development of novel coating materials based on lanthan,ide oxides that, based on their electronic structure, show increased hydrophobicity compared to conventional materials. A coupled ob,jective is to develop processes to deposit coatings using surface conversion, electrodeposition, and slurry-based techniques to incr,easeresistance to salt deposit accumulation while also maintaining strong corrosion and erosion resistance. The technical outcomes w,illenable the implementation of novel coatings offering direct performance enhancement for small- and mid-size vessels and low-flyin,g aircraft operating in marine environments in the Navy?s fleet.
