Study of Plasma Hardening at Nizhny Tagil Branch of Ural Federal University

A The advanced technologies developed by Nizhny Tagil Branch of Ural Federal University in the plasma hardening field have been successfully implemented in manufacturing and continue to be used with a wider sphere of application. The studies of hardening by plasma arch of opposite polarity conducted in the last decade, and the development of the first serial specialized machine UDGZ-200 for plasma hardening, have contributed to the wide use of the process in manufacturing. The increase in application has been due to the inclusion of the surfaces that previously were not, or were insufficiently hardened, for example, working surfaces of toothed and spline couplings, crane wheels and tracks, moulded and blank dies, cases and frames of machine tools.
