    • Choosing and Using Rationally the Thermic Processed Steels 

      Potecașu, Octavian; Potecașu, Florentina (Universitatea "Dunărea de Jos" din Galați, 2012)
      On a global scale one can notice a constant preoccupation for a rational choosing and using of the materials on the whole and, especially of the steels with the main objective the increase of the machines’, equipment’ ...

    • Composite-Decorative Tiles with Granite 

      Potecașu, Octavian; Potecașu, Florentina; Drugescu, Elena (Universitatea "Dunărea de Jos" din Galați, 2006)
      The paper presents the results of the authors’ scientific research on a composite material with polymeric matrix, hardened with rock particles. It was studied the influence of the quantity of the hardening phase on the ...

    • Elastoplastic Model for the Steel Bars Under Thermal Treatments 

      Alexandru, Petrică; Potecașu, Octavian; Potecașu, Florentina (Universitatea "Dunarea de Jos" din Galați, 2005)
      In order to understand material behavior, during the stresses action produced by thermal effects of volume, was started from Hooke relations, whereat was added the expressions that take into account these effects. Have ...

    • Hardened Aluminum with Oxide Particles 

      Potecașu, Florentina; Potecașu, Octavian; Drugescu, Elena (Universitatea "Dunărea de Jos" din Galați, 2006)
      The paper presents the effect of size and dispersion degree of the particles of aluminum oxide, on structure, mechanical characteristics and phenomena that take place when heating at different temperatures for ...

    • Influence of Alloying Elements on Corrosion Resistance of Some Iron - based Sintered P/M Alloys 

      Potecașu, Florentina; Marin, Mihaela; Potecașu, Octavian; Radu, Tamara; Istrate, Gina (Universitatea "Dunărea de Jos" din Galați, 2015)
      In this paper is described the influence of alloying elements on corrosion behavior of sintered iron parts. The compacts were sintered at 1,150 °C and the sintering time was 60 minutes. After microstructural studies, the ...

    • 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 ...

    • The Properties of Hardened Lead 

      Potecașu, Florentina; Potecașu, Octavian; Drugescu, Elena (Universitatea "Dunărea de Jos" din Galați, 2005)
      Lead hardened through oxide scattering is investigated as raw materials for the fabrication of the support gratings of lead accumulators in order to increase their life service. For the preparation of lead powder hardened ...

    • Wear Behavior of Carburizing on Powder Metallurgy Alloys 

      Marin, Mihaela; Potecașu, Florentina; Alexandru, Petrică; Potecașu, Octavian; Drugescu, Elena (Universitatea "Dunărea de Jos" din Galați, 2014)
      In this paper is studied the influence of wear behavior of carburizing in fluidized-bed on sintered alloys produced by powder metallurgy route. In powder metallurgy, carburization is a thermochemically treatment that ...
