The Effects of Process Parameters during the Deposition of SiNx using PECVD. Plasma assisted stands for the state of plasma used to deliver the active species for the process to take place (nitrogen, carbon, oxygen). A glow discharge with a high ionisation level (plasma) is generated around the parts. Applying this thermochemical heat treatment we can produce a very hard surface layer on steels. plasma nitriding procedure accurately by the use of a computer/PLC combi-nation. The reader will find within the text an introduction to nitriding treatment, the basis of plasma and its roll in nitriding. As technology progressed so did the plasma nitriding process. Nitriding materials include a number of steel types: Carbon steels; Hardenable alloy steels; Special nitriding steels such as Nitralloy; High alloy steels: tool steels, heat-resistant steels (e.g. In this low pressure process, a voltage is applied between the batch and the furnace wall.
