Automated Gaseous Nitrocarburizing Controlled by Potentials
<p>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.</p>
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.
