Super High Temperature Erosion and Wear Resistant Ceramic RubberT Coatings

NanoSonic has developed revolutionary nanostructured, inorganic/organic hybrid Metal RubberT and Ceramic RubberT coatings. Specifically, ultra-lightweight (< 0.98 g/cc), nanostructured conformal coatings with low CTE, thermal protection (> 450 C, 842 F) and abrasion / wear resistance with excellent adhesion to metal and PMC substrates with complex shapes are offered. Metal RubberT is fabricated via layer-by-layer, molecular self-assembly, which enables thickness and placement control over multiple constituents for true nanostructured multifunctionality (nm scale). Opposed to PVD, NanoSonic's patented self-assembly process incorporates high temperature, advanced polymers within ceramic or metal coatings and offer controlled thickness (nm thin up to mm thick) on substrates up to 24 square inches. Metal RubberT is a novel nanocomposite formed in situ, by chemically reacting monolayers of nanosized components, thereby eliminating residual stress (overcoming mismatched CTEs) and debonding between each component and the substrate. Ductile Metal RubberT coatings do not crack or spall upon intact due to incorporation of polymers. Hardness of up to 1 GPa has been demonstrated by replacing the metal with ceramics for our Ceramic RubberT coatings, which would be optimized for aircraft engine components such as stator vanes. Sand/grit erosion resistance would be verified at UDRI and with assistance from Lockheed Martin Aeronautics.
