    • Quality Surface Analysis for Polarized Grid Plasma Nitriding 

      Axinte, Mihai; Perju, Manuela-Cristian; Nejneru, Carmen; Hopulele, Ion; Cimpoeșu, Iulian (Universitatea "Dunărea de Jos" din Galați, 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 ...

    • Researches Regarding Temperature Influence on Classic and Synthetic Quenching Medium 

      Grecu, Adrian; Nejneru, Carmen; Axinte, Mihai; Hopulele, Ion; Gălușcă, Dan-Gelu (Universitatea "Dunărea de Jos" din Galați, 2009)
      In this paper were analyzed experimental graphics for quenching cooling curves of oil at 20°C,40°C,60°C, 80°C and carboxymethyl cellulose (CMC) 1,5% solution in water at the same temperatures. Velocity cooling was studied ...
