1. A method of applying a coating to a substrate, comprising:
forming a slurry by mixing elemental precursors of gettering particles, diffusive particles, matrix material, and a carrier fluid;
applying the slurry to a substrate; and
sintering the slurry to form a composite material, whereby the sintering causes the elemental precursors to react with one another to form gettering particles.
