    • Behavior of Some Stainless Nitrided Austenite Steel Types to Corrosion and Abrasion 

      Dima, Ovidiu; Mitoșeriu, Olga (Universitatea "Dunărea de Jos" din Galați, 2006)
      By nitriding, stainless austenite steel types can become surface hardened. Hardness can be greater at more than 1000 HV005 when the composition layer made of complex nitrides is obtained and more reduced till 500 HV005 ...

    • Decorative composite Layers 

      Mitoșeriu, Olga; Potecașu, Florentina; Drugescu, Elena; Vlad, Maria (Universitatea "Dunărea de Jos" din Galați, 2008)
      Part of the materials used in the chemical industry, metallurgical, machine construction, can be coated, as with time it occurs either a decrease of its properties, or even a process of advanced faulting, because of the ...

    • Electrodeposition Obtaining and Corrosion Behaviour of Phenol Formaldehyde Resin/Zinc Composite Coatings 

      Mitoșeriu, Olga; Ciubotariu, Alina; Benea, Lidia; Ponthiaux, Pierre; Wenger, Francois (Universitatea "Dunărea de Jos" din Galați, 2008)
      The present work has the purpose of obtaining composite coatings in zinc matrix by using phenol - formaldehyde resin type NOVOLAC (RESITAL 6358/1) in the electrodeposition process of zinc. The PF resin/Zn composite ...

    • Kinetic of Nitroso R-Salt Sorption on Amberlite IRA 402 Resin 

      Rădulescu, Eugen; Cantemir, Gheorghe; Mitoșeriu, Olga; Stanciu, Constantin (Universitatea "Dunărea de Jos" din Galați, 2005)
      The sorption of nitroso R salt from aqueous solution by ion exchange resins, such as AMBERLITE IRA 402 (Cl- form) , is described. The experimental data have been analyzed by using the sorption kinetics for a first-order ...

    • Mercury Determination from Incidentally Polluted Waters by Collecting Gravimetry in Organic Stage Method 

      Mitoșeriu, Olga; Levcovici, Dan T.; Filip, Gabriela (Universitatea "Dunărea de Jos" din Galați, 2006)
      Determination of mercury in incidentally polluted waters, presented in CALIST Program, was carried out using tiobis-β-naphthol as a reagent. The method proposed for mercury determination, named “collecting gravimetry in ...

    • Morphological Aspects and Corrosion Behaviour of Phenol Formaldehyde/Zn Composite Coatings 

      Ciubotariu, Alina-Crina; Benea, Lidia; Mitoșeriu, Olga; Ponthiaux, Pierre; Wenger, François (Universitatea "Dunărea de Jos" din Galați, 2009)
      The present work has the purpose of studying morphological aspects and corrosion behaviour of pure zinc and composite coatings having zinc as metal matrix and phenol – formaldehyde resin type Novolac (RESITAL 6358/1) ...

    • Selective Organic Reactive for Determination of Several Heavy Metals from Different Materials 

      Mitoșeriu, Olga; Levcovici, Dan T.; Filip, Gabriela (Universitatea "Dunărea de Jos" din Galați, 2006)
      The research regarding the synthesis and characterization of tiobis-β- naphthol have established that it can be used as an efficient analytical reactive for separating through extraction the heavy metals in watery env ...

    • Structure-Property Correlation of Composite Materials Based on Cu-Mo obtained by PVD Method 

      Orac, Lucica; Grechanyuc, Vera; Mitoșeriu, Olga; Constantinescu, Stela (Universitatea "Dunărea de Jos" din Galați, 2013)
      The paper describes reviews referring to determination of working parameters of the development processes of composites in copper matrix, by vapour-phase deposition method. The molybdenum was used as complementary phase. ...

    • Study and Researche Regarding Binaring Sistem with TIOBIS - β – NAFTOL 

      Mitoșeriu, Olga; Constantinescu, Stela; Orac, Lucica (Universitatea "Dunărea de Jos" din Galați, 2007)
      This paper presents the results for contribution of determining the manganese from waters and steel. Manganese, due to its properties, cannot be found but in acid waters and usually associated with iron. In small amounts, ...
