    • Behavior of 1% Cr Steels at Fluidized Bed Nitrocarburizing 

      Dobrovici, Sorin; Cazacu, Nelu; Bâclea, Adolf; Drugescu, Elena (Universitatea "Dunărea de Jos" din Galați, 2005)
      Paper is based by nitrocarburizing experiments made on pilot installation. For experiments were used different samples of steel at different nitrocarburizing regimes. Influence factors were: temperature and ammonia ...

    • Behavior of 1%Cr Steels at Fluidized Bed Nitrocarburizing 

      Dobrovici, Sorin; Cazacu, Nelu; Bâclea, Adolf; Drugescu, Elena; Preda, Nelu (Universitatea "Dunărea de Jos" din Galați, 2006)
      Paper is based by nitrocarburizing experiments made on laboratory plant. For experiments were used different samples of steel at different nitrocarburizing regimes. Influence factors were: temperature and ammonia ...

    • Behavior of Rp3-High Spped on Short Time Nitriding in Fluidized Bed 

      Bâclea, Adolf; Cazacu, Nelu; Dobrovici, Sorin; Drugescu, Elena; Potecașu, Octavian (Universitatea "Dunărea de Jos" din Galați, 2005)
      For steel nitriding, treatment time is a important factor. Gas and plasma nitriding are usual method to increase surface properties by nitriding. A close retort is used. Total time for treatment are higher because are ...

    • Nanostructured Surface for 38MoCrA109 Steel by Nitriding in Nitrogen Atmosphere and Yag;Nd Pulse Laser Activation 

      Cazacu, Nelu; Pintilie, Cătălin; Dobrovici, Sorin; Bâclea, Adolf (Universitatea "Dunărea de Jos" din Galați, 2008)
      YAG:Nd pulse laser is usually used for cutting and welding. The paper is based by experiments using YAG:Nd pulse laser (KVANT 17-CIS made). Technological modules were assembled for laser beam deviation and for relative ...

    • Oxidizing Influence Over Surface Structures and Properties for A3k Steel Nitrocarburized in Fluidized Bed 

      Cazacu, Nelu; Dobrovici, Sorin; Bâclea, Adolf; Tănăsescu, Victor; Preda, Nelu (Universitatea 'Dunărea de Jos" din Galați, 2006)
      Surface duplex thermochemical treatment (oxinitrocarburizing) has principal scope to obtaining superficial mechanical higher properties with increasing corrosion capacity. The paper is based by oxinitrocarburizing ...

    • 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 ...
