    • Behavior of A537 Steel Grade in Carburizing in Fluidized Bed with Endothermic Atmosphere 

      Dobrovici, Sorin; Cazacu, Nelu (Universitatea "Dunărea de Jos" din Galați, 2009)
      Fluidized bed allows one to easily change from the chemical composition of the working atmosphere. The paper is based on experiments of carburizing in fluidized bed with endothermic atmosphere made from gases resulting ...
    • 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 ...
    • 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 Hardenining for 38MoCrA109 Steel Using Fluidized Bed Nitriding 

      Baclea, Adolf; Dobrovici, Sorin; Cazacu, Nelu (Universitatea "Dunărea de Jos" din Galaţi, 2008)
      The paper is based an nitriding experiments made in a fluidized bed laboratory furnace. Fluidization was obtained in a steel refractory retort by solid granular (burned fire clay) and fluid (mixture of ammonia and ...
