Systems and methods for forming an oxidation protection system on a composite structure are provided. In various embodiments, an oxidation protection system disposed on a substrate may comprise a boron-silicon-glass layer formed directly on the composite structure. The boron-silicon-glass layer may comprise a boron compound, a silicon compound, and a glass compound.

The method consists of the formation of a layer over a stone substrate to increase its hardness, chemical resistance, wear and scratch resistance, comprising applying on the substrate a coating matrix incorporating an organic material and fillers including inorganic nanoparticles and/or microparticles; chemically binding said matrix to the substrate, by a self-assembly process and/or a binding process by covalent bonding, electrostatic bonding, van der Waals bonding or hydrogen bonds; and finally drying said matrix. The mentioned organic material is selected from organosilanes, organophosphates, polycarboxylic compounds, compounds based on triazine heterocycles and said nanoparticles are nanoparticles of oxides, carbides, borides, nitrides of metals or of semimetals.

Thin films of precious metals such as platinum and gold have the required ability to withstand high temperatures, but in pure form can suffer from grain growth, agglomeration and dewetting at high temperature. Grain boundaries must therefore be pinned by alloying with other metals and/or by inclusion of non-metallic nanoparticles. While such bulk materials are known in the prior art, they have not existed previously as printable inks that can be deposited by additive manufacturing direct-write methods. These materials have been formulated for the first time as alloy and composite inks so that they may be applied by direct-write additive manufacturing techniques directly onto three-dimensional components or on high temperature substrates that can be adhered to complex components.
