    • 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% ...

    • Laser Cladding of Ni-Cr-B-Fe_Al Alloy on a Steel Support 

      Levcovici, Sanda Maria; Levcovici, Dan Teodor; Gheorghieș, Constantin; Boiciuc, Simona (Universitatea "Dunărea de Jos" din Galați, 2005)
      Multilayer coating by injection of powder with 8.9% Cr, 4.5% Fe, 5.1% B, 2.4% Al, 0.6% Cu; all reminded of Ni, as chemical composition, in melted bath by CO2 continuous wave laser connected to x-y-z coordinate table was ...

    • Tribological Behaviour of Nitrocarburized Steels After Thermo-Magnetic Treatments 

      Papadatu, Carmen Penelopi (Universitatea "Dunărea de Jos" din Galaţi, 2008)
      Two types of steels were subjected to a nitro-carburized thermo-chemical treatment after thermo-magnetic treatments. The structural aspects into the superficial layer of these steels are studied during the friction process ...
