PROCESSES The Effects of Process Parameters during the Deposition of SiNx using PECVD. An alternative or supplement to gas nitriding is ion nitriding, or plasma nitriding, in which the steel objects are bombarded with nitrogen ions in a vacuum under an electric charge. The Life of WC-Co Cutting Tools Treated by Plasma Immersion Ion Implantation. Al Paste Printing. University of Washington. Plasma nitriding produces high surface hardness, good wear resistance, increased fatigue strength and toughness. Nitriding THE NITRIDING PROCESS, first developed in the early 1900s, con-tinues to play an important role in many industrial applications.
