Gaseous Nitrocarburizing, Automatically Controlled by Potentials
This specification covers the requirements for producing a continuous compound layer with controlled phase composition 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 compound layer which establishes properties such as wear and corrosion resistance, ductility and fatigue strength.
AMS 2759/12A corrects errors, updating the text of 3.6.5 and the Table 1 heading for column 5 to become consistent with the porosity percentage range of 10 to 50% established by paragraph 1.3.2.
