Title: Innovative Silicon Nitride - Zirconium Dioxide Nanocomposites for Turbine Engine Applications
Agency / Branch: DOD / DARPA
Contract: W31P4Q-07-C-0170
Award Amount: $99,000.00


The objective of this Phase I SBIR is to develop zirconium dioxide - silicon nitride nanocomposites as high temperature, corrosion resistant thermal barrier coatings for turbine engine components. The novel nanocomposite coatings would consist of zirconium dioxide nanoparticles encapsulated with innovative polysilazane copolymers designed to complex / disperse the nanoparticles, afford exceptional adhesion to metallic substrates, and transition to high performance silicon nitride matrices with exceptional thermomechanical properties. NanoSonic researchers believe its polysilazane - zirconium oxide complexes afford a unique alternative to the current state-of-the-art EB-PVD zirconia coatings as they may be pyrolyzed to low density ceramic coatings with 1) enhanced adhesion to metallic substrates (potentially displacing commonly employed alumina bond coats lines), 2) greater strain tolerances to limit unwanted spalling, 3) enhanced high temperature corrosion and oxidation resistance (1000 - 2000 C), 4) improved wear resistance / fracture toughness, and 5) reduced thermal conductivities. During Phase I of the program, researchers at NanoSonic would work to synthesize a family of polysilazane- zirconium oxide nanoparticle complexes, deposit the nanocomposite resins on metallic substrates using spray or solution cast techniques, convert the polysilazane copolymers to high performance silicon nitride matrices, and evaluate nanocomposite corrosion performance.
