    • Austenitic Stainless Steels Corrosion Properties Modified by Silicon Alloying 

      Ghiban, Brândușa; Ciucă, Sorin (Universitatea "Dunărea de Jos" din Galați, 2007)
      In the present paper there are presented results concerning comparative corrosion resistance of some austenitic stainless steels, with or without silicon content. The silicon content is varying in the range of 1-5 %, in ...

    • Characterization of Dental Metals and Alloys 

      Vasilescu, Elisabeta; Vasilescu, Vlad-Gabriel; Nicolau, Alexandru Mircea (Univesitatea "Dunărea de Jos" din Galați, 2013)
      Metals and alloys in dentistry have seen remarkable progress due to their biocompatibility and deepen research on the application of advanced technologies to improve surface properties by controlling interactions material ...

    • Corrosion of Composite Ferro-Niobium Layers in Cobalt Matrix 

      Balint, Lucica; Radu, Tamara; Balint, Simion Ioan (Universitatea "Dunărea de Jos" din Galaţi, 2012)
      The ferro-niobium composite layers in cobalt matrix were obtained by cathode depositing from electrolyte solutions on steel base. The electrolyte included in its composition cobalt sulphate and cobalt chloride, boric ...

    • 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 ...

    • Ni-P Coating on Steel Support by Electroless Method 

      Radu, Tamara; Dobrea, Andreea Georgiana (Universitatea "Dunărea de Jos" din Galați, 2017)
      The autocatalytic reduction method (electroless method) was applied to obtain the Ni-P layers with different P contents. Nickel sulfate was used as nickel ion source and as reducing agent the sodium hypophosphite. The ...

    • On the Corrosion Resistance of Cu-Mo Composite Materials Obtained by PVD Method 

      Grechanyuk, V.G.; Grechanyuk, N.I.; Orac, L.; Denisenko, V.A. (Universitatea "Dunărea de Jos" din Galați, 2008)
      The Cu – Mo composite materials have been obtained by electron flow vaporizing followed by vapor –phase condensing. Researches have shown that corrosion resistance in wet environment varies with the content of ...

    • Study Regarding Gravimetrical Corrosion of the Superficial Layers Obtained Through Electrical Discharge 

      Barhalescu, Mihaela; Dinescu, Maria; Pascu, Rovena (Universitatea "Dunărea de Jos" din Galați, 2009)
      The experimental research was made on superficial layers laid-down through electrical sparking on the steel carbon OLC 45 probes, the used electrode being made from a corrosion resistant material (Copper). The probes ...
