Investigation of Electrical Discharge Processes During Electrolytic-Plasma Nitrocarburizing. [PDF]

Materials (Basel)
In this study, the process of electrolytic–plasma nitrocarburizing (EPNC) of 20-grade steel was investigated using various electrolytes and temperature regimes. At the first stage, optical spectral analysis of plasma emission during EPNC was carried out with spectral registration in the range of 275–850 nm, which allowed the identification of active ...
