    • Cladding by Welding with Hard Alloys 

      Dima, Ovidiu (Universitatea "Dunărea de Jos" din Galați, 2009)
      The paper presents the results of a research on the role of cladding by welding support of continuous casting plant. Emphasizing that plating leads to outer layer the study presents a complex of properties favorable for ...

    • Coating of the Lasting Moulds with Hard Alloys 

      Dima, Ovidiu (Universitatea "Dunărea de Jos" din Galați, 2010)
      This paper presents the researches on the welded coating of lasting moulds used for casting at high melting temperatures. It shows that the coating through the flux welding with the addition of metal powders and graphite ...

    • Durabilyty of Friction Pairs With Functionality in Abrasive Randomly Particles 

      Tudor, Andrei; Vlase, Monica (Universitatea "Dunărea de Jos" din Galaţi, 2007)
      It is shown that the abrasive particles, which penetrate in the convergent joint of friction pairs, can damage the superficial layer of surfaces. The wear caused by individual particle depends on having both a satisfactory ...

    • Mechanical properties and Abrasive Wear Behavior of Fluidized-bed Carburized Sintered Iron Alloys 

      Marin, Mihaela; Potecașu, Florentina; Drugescu, Elena; Potecașu, Octavian; Alexandru, Petrică (Universitatea "Dunărea de Jos" din Galați, 2012)
      This paper is a study of the influence of fluidized bed carburizing of sintered steels on the mechanical properties and the abrasive wear behavior for two different types of powder. Carburizing was carried out at a ...

    • Reasearches Regargindg the Influence of Steam Oxidation on Sintered Alloys Properties 

      Marin, Mihaela; Potecaşu, Florentina; Potecaşu, Octavian (Universitatea "Dunărea de Jos" din Galaţi, 2013)
      In this paper is studied the influence of steam treatment applied on sintered steels and the mechanical properties and abrasive wear behavior for two different types of powder. Steam treatment was carried out at temperature ...

    • Research on the Influence of the Complementary Phase Percentange on the Properties of Copper-Based Composites 

      Boiciuc, Simona; Alexandru, Petrică (Universitatea "Dunărea de Jos" din Galaţi, 2014)
      The article presents the method to obtain copper matrix composite with Cu- Al-Fe alloy particles as complementary phase. The samples were obtained by powder metallurgy methods using different percentages of complementary ...

    • Research on the Production of Sintered Powder 316 

      Boiciuc, Simona; Potecașu, Florentina (Universitatea "Dunărea de Jos" din Galați, 2012)
      The 316 austenitic stainless steel powders are typically used in applications requiring good corrosion resistance, mechanical strength at high and very low temperatures, good ductility, wear resistance, associated in ...
