Abstract
Provided are extrusion tools such as extrusion dies or portions thereof having a surface with at least one coating thereon, and methods of forming the same are disclosed. The at least one coating is formed from a composition that is a metal aluminum nitride or carbonitride with particular characteristics such that the amount of aluminum varies within the coating between a coating outer surface and an intermediate thickness within the coating. The resulting coatings have tailored physical and performance characteristics that result in improved wear and extrusion performance.
