Resistant Coatings for Metal Turbine Blades

The Joint striker fighter (JSF) concept was to design a new fighter plane that can serve for all three defense branches, Air Force, Navy and Army. The concept required coming up with new engines and aircraft designs with improved capabilities and cost effective manufacturing technologies. Advanced erosion resistant coatings will play a crucial role in the engine systems by providing vital erosion, corrosion and thermal protections for engine components in the harsh sand ingestion, erosive and/or combustion gas environments. From experiments conducted it is concluded that such coating materials should have high toughness, adherence to the part’s surface, moderate hardness and chemical stability at high temperature. All these capabilities could be obtained in Ti-B-N material system because of its unique capability of mixing various phases with contrasting properties. The method developed here is based on well established deposition processes that can be used to form suitable nano-composite architecture possessing the required qualities.
