    • 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 ...

    • 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 ...
