- Description
- statement of work capability statement NASA Advanced Environmental Barrier Coatings Deposition for SiC/SiC Ceramic Matrix Composites and Thermoelectrics NASA intends to purchase turbine airfoil environmental barrier coating systems on SiC/SiC Ceramic Matrix Composite (CMC) components or Thermolectric devices using high temperature Directed Vapor Electron Beam-Physical Vapor Deposition based techniques. The environmental barrier coating systems shall be processed based on NASA coating composition and microstructural specifications, on to NASA supplied substrates or devices. A two-layered directed vapor deposition coating systems with non-line-of sight processing are also preferred for 1 inch x 1 inch SiC/SiC CMC coupons, 6"x0.5" dogbone specimens and with other SiC/SiC witness specimens or additional optimization specimens for deliveries. The performance of the coatings shall be studied and evaluated at NASA Glenn Research Center or NASA funded Contracts for NASA Aeronautic Research Mission Directorate (ARMD) Transformational Tools and Technologies (TTT) Project and Related NASA GRC Collaboration Project with NASA Jet Propulsion Laboratory (JPL). The Salient features of the NASA vapor EBC development include two tasks: Task I. Environmental Barrier Coating Processing for SiC/SiC Ceramic Matrix Composites Multicomponent rare earth containing multi-nanolayer oxide-rare earth-HfO2 silicon-silicate composite toughening based EBC bond coat systems shall be processed onto Forty-Eight (48) NASA supplied SiC/SiC ceramic matrix composite (CMC) specimens and coupon subelements (1 inch x 1 inch or 6x0.5" tensile bars) with the required environmental barrier bond coating and top coat processing runs, using NASA specified bond coat compositions and meeting total thickness requirements. The bond coat runs for the specimens shall be processed in controlled temperatures and low oxygen partial pressures, and using plasma activation to achieve high density and composition uniformity, with two-layer and three-layer rare earth-hafnia-silicon based bond coat systems. The bond coat processing shall also use alternating and co-deposition approaches as specified, and producing uniform coating thicknesses of up to 76 micrometers and covering all surfaces of the specimens and components for environmental protections and testing requirements. The environmental barrier coating processing shall also include a top layer consisting of advanced hafnia-rare earth oxide-silicate based environmental barrier coatings specified by NASA, for evaluation and demonstration of 2700°F temperature capability and ultra-high temperature ceramic applications. NASA EBC coating experience learnt from the previous NASA projects shall be incorporated to this task aiming at continuing process improvements in coating density and performance. Task II. Directed Vapor Environmental Barrier Coating Processing for Thermoelectric Device and Systems: The environmental barrier coating systems shall be processed with NASA specified barrier coating compositions and thicknesses including Rare Earth Oxides/Silicates, Alumina-Rare Earth Aluminates and Garnets, and/or Rare Earth Zirconate or Hafnate composition systems. The coatings shall also be processed onto Sixty (60) NASA supplied thermoelectric devise coupon specimens or device subelements (with dimensions approximately 1 inch x 1 inch square coupons or 1" diameter discs). The coating processing shall have approximately up to 127 to 152 micrometers coating thicknesses and consistent compositions. The coating composition and processing shall be performed and optimized for the thermoelectric performance and high temperature long-term test durability. NASA EBC experience learnt from the previous tasks will be incorporated to this task aiming at continuing process improvements. The two coating processing tasks are also in conjunction with a NASA SBIR Phase II (Phase II NNX15CC29C) Enhancement Contract (pending Approval) for the further advancements of coating processing and deposition capabilities. This SBIR Phase II Enhancement Contract should further enable high performance down-selected coating systems, supporting expanded testing matrix at NASA GRC or other NASA designated test locations in simulated operating conditions, by delivering additional advanced environmental barrier coatings or process optimizations to support NASA testing and modeling efforts.
