Abstract
A method of making a gasket having a high temperature coating that includes obtaining a substrate formed from a metallic material and having the shape of a gasket, applying a nanoparticle suspension over the outer surfaces of the substrate, and heating the substrate to a first elevated temperature to form an undercoat layer of a self-protective oxide coating. The method also includes applying a liquid comprising boron nitride over the undercoat layer and drying the boron nitride liquid at a second elevated temperature to form an overcoat layer.
