1. A method of applying an inorganic material to a metal substrate that comprises a metallic material that undergoes transformation to an austenitic phase at an austenite transformation temperature, the method comprising:
depositing inorganic particles onto a surface of the metal substrate at a deposition temperature that does not cause the metallic material to exceed the austenite transformation temperature of the metallic material, and
depositing additional inorganic particles onto the inorganic particles in one or more additional deposition processes to form a multi-layer abrasion-resistant coating comprising a boron-doped titanium carbonitride layer and a titanium carbonitride layer,
wherein a deposition temperature of the one or more additional deposition processes does not cause the metallic material to exceed the austenite transformation temperature of the metallic material.
