Quality Surface Analysis for Polarized Grid Plasma Nitridings
The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2013 For the study regarding the effect of the polarized grid a prototype plasma nitriding facility was used. A polarized grid was placed inside the working chamber, into the space between the anode and cathode, a negative polarised grid.
