PLASMA NITRIDING THESIS

B, 2 , Each nitriding unit in the cascaded system works as a miniature nitriding reactor with a substantial reduction of processing time in heating and cooling. Both the mini- and micro-nozzles were also utilized to selectively harden the through-hole surfaces.

With an increase in ion density, the nitriding process is enhanced by increasing the nitrogen atoms and NH—radical flux into the depth of the pipe thickness.

Low Temperature Plasma Nitriding of Inner Surfaces in Stainless Steel Mini-/Micro-Pipes and Nozzles

Besides, the steel also exhibited the best fatigue performance in plasma nitriding condition. In order to ignite the nitrogen plasmas only in the nozzle through-holes as well as the pipes, the RF-plasmas were confined in the inside of electrically conductive space. Nitridinv of surface properties of various plasma nitrided low alloy steels.
