    摘要: A method of laser treating a zirconia surface can include surface texturing zirconia using a combination of ablation and melting. The method includes forming a carbon film on the zirconia surface and laser treating the carbon-coated zirconia surface. The carbon film can include titanium carbide (TiC) and boron carbide (B4C), for example. The carbon film can include titanium carbide (TiC) and boron carbide (B4C) in equal proportions. The carbon-coated surface can then be scanned with a nitrogen gas-assisted CO2 laser beam to form a laser-treated surface. The laser-treated surface can include ZrN compounds. The present method can enhance the surface properties of zirconia and improve the structural integrity of zirconia.

    摘要: In some examples, a method includes identifying a damaged area in a ceramic matrix composite coating of an in-service component; applying a restoration slurry to the damaged area of the ceramic matrix composite coating, wherein the restoration slurry comprises a liquid carrier and a restoration coating material; drying the restoration slurry to form a dried restoration slurry; and heat treating the dried restoration slurry to form a restored portion of the ceramic matrix composite coating. In some examples, an assembly may include a component including a substrate and a coating on the substrate, where the coating defines a damaged portion; masking around the damaged portion on undamaged portions of the coating; and a restoration slurry in the damaged portion, wherein the restoration slurry comprises a liquid carrier and a restoration coating material.

    摘要: The present invention solves numerous problems in state-of-the-art industrial anti-corrosion protection by using a reactive silicon oxide precursor solution. Among the problems solved are those of decreased heat transfer over a protected surface, limited protection against high-temperature corrosive fluids and difficulties in protecting complex 3D geometries and surfaces with a high surface roughness. The present invention furthermore provides an easy way of making chemical surface functionalization using e.g. silane chemistry. The invention solves these problems by coating the surface of a ceramic or metallic part with a thin layer of a liquid solution of a reactive silicon oxide precursor (rSiO-p) such as Hydrogen Silsesquioxane (HSQ) in Methyl Isobytul Ketone (MIBK) or volatile methyl siloxane (VMS), heating the part to a curing temperature of the rSiO-p, and after a curing time the reactive silicon oxide precursor is transformed into a thin layer of essentially pin-hole free silicon oxide.
