After World War II the plasma nitriding process received widespread acceptance in Germany, Russia, China and Japan. Ltd., Savli, MEE1005 Materials Engineering and Technology-L5, No public clipboards found for this slide. Plasma nitriding, nitrocarburising and post-oxidation are plasma assisted thermochemical treatments. The process was not introduced into the United States until after 1950 and has only been used as a production process for the past 20-25 years. Plasma Nitriding in general is a heat treating that is used to case harden surfaces using nitrogen. Ch.30 ... Ionized hot gas containing equal shares of electrons and ions. Plasma assisted stands for the state of plasma used to deliver the active species for the process to take place (nitrogen, carbon, oxygen). Plasma nitriding can be further branched out into plasma nitrocarburising. Now customize the name of a clipboard to store your clips.
