…A method is also used to create a surface hardening layer by depositing special alloys such as cemented carbide or Stellite (an alloy of about 30% chromium, 20% tungsten, 0.1-0.3% carbon, and the remainder cobalt) on the surface of a metal material, and this method is also called hard facing. There is also a method of infiltrating the surface of steel with a cemented carbide such as tungsten carbide (WC) in a reducing atmosphere at 1000-1100°C (carbide infiltration method or atomloy treatment). It is applied to tools such as dies and punches. … *Some of the terminology used in reference to "Atomroy Processing" is listed below.
