    • Study for Evaluation and Optimization of Mineral Composition and Structure of Iron Ore Granulation in Sintering Process 

      Mogoş, Paul Petruş; Constantin, Nicolae; Ittu, Sînziana; Anca, Denisa-Elena; Harcea, Lavinia-Marilena (Universitatea "Dunărea de Jos" din Galaţi, 2012)
      The characterization of iron ore particles is of vital importance for the study of mineral composition. The specific surface area of iron ore particles can be measured by laser diffraction, and mathematical models (based ...

    • The Corrosion Behaviour of Aluminum Alloy 2024-T3 in Acidic Environments 

      Hotea, Vasile; Juhasz, Jozsef; Pop, Elena; Iepure, Gheorghe; Pop, Aurica (Universitatea "Dunărea de Jos" din Galaţi, 2012)
      This research aimed at analysing the acidic corrosion behavior of aluminum alloy 2024-T3 commonly used in the aerospace. We study the variation of corrosion rate with immersion time at different values of H2SO4 concentration ...

    • The Dental Technology in Art Foundry 

      Florea, Gheorghe; Doniga, Ana; Florea, Bogdan (Universitatea "Dunărea de Jos" din Galaţi, 2012)
      The paper presents results of a study undertaken to implement the dental casting technique of small parts characterized by extremely complex drawings of surfaces and thicknesses reduced specific objects. During the study ...

    • The Influence of Steam Treatment on Mechanical Properties and Abrasive Wear Behavior of Sintered P/M Steels 

      Marin, Mihaela; Potecaşu, Florentina; Drugescu, Elena; Potecaşu, Octavian; Alexandru, Petrică (Universitatea "Dunărea de Jos" din Galaţi, 2012)
      In this paper is a study of the influence of steam treatment on sintered P/M steels, for three different types of powder. The abrasive wear of steam-treated sintered iron is analysed by abrasion tests. The specimens were ...
