Joint surface coatings for ceramic components

A method comprising:

• holding a first joining surface of a coated component comprising a substrate adjacent a second joining surface of a second component, wherein the substrate comprises a first ceramic coated with a joint surface coating, wherein the joint surface coating comprises a first diffusion barrier layer, a first compliance layer, a second diffusion barrier layer, and a second compliance layer, wherein the first diffusion barrier layer comprises a second ceramic, wherein the first compliance layer comprises at least one of a metal or a metalloid, wherein the first compliance layer is a continuous layer on an outer surface of the substrate between the first diffusion barrier layer and the substrate, wherein the second compliance layer is between the first diffusion barrier layer and the second diffusion barrier layer;
• wherein the second diffusion barrier layer comprising a third ceramic, wherein the second compliance layer comprises at least one of a metal or a metalloid, wherein the at least one of the metal or the metalloid of the second compliance layer is different than the at least one of the metal or the metalloid of the first compliance layer;
• heating at least one of the coated component, the second component, and a braze material;
• and
• brazing the coated component by allowing the braze material to flow in a region between the first joining surface and the second joining surface.
