    • Dimensional Changes in Some Iron-Based Powder Metallurgy Alloys 

      Marin, Mihaela; Potecașu, Florentina; Potecașu, Octavian (Universitatea "Dunărea de Jos" din Galați, 2015)
      The purpose of this paper is to present the dimensional changes in some ironbased (P/M) alloys. The specimens produced from atomized iron powder and alloyed powder with different sizes (< 45, 45-63, 63-100, 100-150, >150 ...

    • 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 ...

    • Studies and Research Obtaining Bronze Filters Using Powder Metallurgy Methods 

      Boiciuc, Simona; Alexandru, Petrică (Universitatea "Dunărea de Jos" din Galați, 2015)
      The article presents how to obtain porous bronze products using copper - based powder by powder metallurgy methods. The formation of tablets was done by free pouring the spherical powder into the mould, followed by their ...
