• 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 ...
    • Development of Blade Design for Small Hawt Adapted for Lower Values of Wind Speed 

      Badea, Nicolae; Cazacu, Nelu (Universitatea "Dunărea de Jos" din Galați, 2009)
      The paper aims at studing, theoretically and experimentally, the influence of turbines blade profile on output power, in order to decrease effective domain to smaller wind speed, specific to Galati area. Studies have ...
    • Surface Hardening by Nitration for Some Stainless Austenite Steel Types 

      Dima, Ovidiu; Cazacu, Nelu (Universitatea "Dunărea de Jos" din Galați, 2006)
      Stainless austenite steel types have a good resistance to corrosion in different natural, industrial environments but their hardness and mechanical resistance are low enough. In order to assure an increased resistance ...
    • 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 ...
