    • Characterization of Iron and Low Alloy Steel Powders Obtain by Water Atomization 

      Drugescu, Elena; Marin, Mihaela; Silva, Rui (Univerversitatea "Dunărea de Jos" din Galați, 2009)
      Three types of iron and low ally steel powders were investigated to determinate their physical properties and surface morphology by SEM analysis. The powders were obtained by water atomization. The first type of powder ...

    • Characterization of Thick Hard Layers with ni-Cr-B-Fe-Al Alloy Obtained by Laser Cladding 

      Drugescu, Elena; Boiciuc, Simona; Gheorghieș, Constantin (Universitatea "Dunărea de Jos" din Galați, 2009)
      To increase the resistance to wear and corrosion of the surface layers made from steel with 0.45% C, multilayer deposition was tested by injection of powder with chemical composition of 8.9% Cr, 4.5% Fe, 5.1% B, 2, 4% ...

    • EDX Analysis of Laser Cladding Layers with Ni-Cr-B-Fe-Al Alloy 

      Boiciuc, Simona; Drugescu, Elena; Miculescu, Florin; Cantaragiu, Alina (Universitatea "Dunărea de Jos" din Galați, 2009)
      Multilayer cladding by injection of powder with 8.9% Cr, 4.5% Fe, 5.1% B, 2.4% Al, 0.6% Cu, Ni rest as chemical composition, in melted bath by a continuous wave CO2laser connected to x-y-z coordinate table was tested in ...
