Purpose This specification covers the requirements for producing a continuous white layer with controlled extent of porosity by means of a gaseous process@ automatically controlled to maintain set values of the nitriding and carburizing potentials that determine properties of the nitrocarburized surface. Automatic control is intended to ensure repeatability of nitrogen and carbon content of the white layer which influences properties such as wear and corrosion resistance@ ductility and fatigue strength. Application The nitrocarburizing process described herein is used typically for enhancement of wear resistance and fatigue strength@ as well as corrosion resistance in ferrous alloys but usage is not limited to such applications. The provisions of this specification revision shall become effective 90 days after publication. Safety ?C Hazardous Materials While the materials@ methods@ applications@ and processes described or referenced in this specification may involve the use of hazardous materials@ this specification does not address the hazards which may be involved in such use. It is the responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
