    • Surface Hardening of 40Cr10 steel After Short Time Nitriding in Fluidized Bed 

      Bâclea, Adolf; Dobrovici, Sorin; Drugescu, Elena; Cazacu, Nelu; Preda, Nelu (Universitatea "Dunărea de Jos" din Galați, 2006)
      The paper is based by nitriding in fluidized bed experiments over laboratory plant. Fluidization applications are characterized by high values of mass and heat transfer coefficients. For experiments were used 40Cr10 ...

    • Surface Hardening Over 38MoCrA109 Steel by Yag:Nd Pulse Laser 

      Dobrovici, Sorin; Cazacu, Nelu; Sava, Liliana; Baclea, Adolf (Universitatea "Dunărea de Jos" din Galați, 2008)
      Laser offers unique capabilities for high energy concentrations at small surfaces. Factors that have influences over interactions between laser beam and steel surfaces have very high control. Pulse laser YAG:Nd is usually ...

    • Utilisation of Electrochemical Methods for Characterization of Some Corrosion Inhibitors for Steel and Copper 

      Constantin, Florina; Abrudeanu, Mărioara; Millet, Jean-Pierre (Universitatea "Dunărea de Jos" din Galați, 2009)
      The effect of chromate and molybdate on the corrosion inhibition of copper and steel has been investigated in two eutectics solution at room temperature. We used stationary electrochemical methods and optical microscopy ...
