      Țugui, Cătălin-Andrei; Vizireanu, Petrică; Nejneru, Carmen; Perju, Manuela-Cristina; Axinte, Mihai; Bălțatu, Simona-Mădălina (Universitatea "Dunărea de Jos" din Galați, 2015)
      The properties of metallic materials can be improved by deposition of materials. The coating has a tear strength and better hydro-abrasive corrosion. The thin layer deposition has a thickness of less than 10 micrometers. When ...
    • Hardening of the Grey Cast Iron Through the Vibrating Electrode Method Using a WC Electrode and in Combination with Ti Electrode 

      Perju, Manuela Cristina; Nejneru, Carmen; Răileanu, Tudor; Axinte, Mihai; Hopulele, Ioan (Universitatea "Dunărea de Jos" din Galaţi, 2008)
      There have been tested samples of grey cast iron, the hardening being made through WC coating through the vibrating electrode method with a layer, two layers and through double layers combined with Ti and TiC. Besides ...
    • 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 ...
