    • Copper Plating Corrosion Study in Certain Environments 

      Cantaragiu, A.M.; Gavril (Donose), M.D.; Vladu (Radu), D.C.; Gheorghieș, C.; Tigău, N.; Cantaragiu, C.M. (Universitatea "Dunărea de Jos" din Galați, 2013)
      Copper plating was performed on nickel substrate by means of the potentiostatic electrodeposition method from a sulphate electrolyte solution. The copper coatings morphology was studied by means of the optical and ...

    • Preparation and Characterization of Tin Oxide thin Films 

      Țigau, N.; Vladu Radu, D. C.; Prodan, G.; Gheorghieș, C.; Condurache-Bota, S. (Universitatea "Dunărea de Jos" din Galați, 2013)
      Tin oxide (SnO) thin films were prepared onto glass substrates by thermal evaporation under vacuum. The substrate temperature was kept constant at 300 K during the film growth. The structural studies using transmission ...

    • Prreparation and Characterisation of Alumina Template Obtained by One-Step Anodization Method 

      Gavril (Donose), M.D.; Cantaragiu, A.M.; Gheorghieș, C.; Țigău, N.; Donose, S. (Universitatea 'Dunărea de Jos" din Galați, 2013)
      The goal of this study was to obtain an alumina template (AAO) by one-step anodization method and to evaluate its optical properties correlated with the annealing temperature. AAO was obtained from two different media: ...

    • Semi-Planetary Rolling and Changes of Fine Structure and Microstructure 

      Gheorghieș, C.; Cănănău, N.; Alexandru, P.; Petrea, I. (Universitatea "Dunărea de Jos" din Galați, 2007)
      The strain intensity in the proximity of planetary cylinder, in the case of semi-planetary rolling is greater than in the proximity of the massive cylinder. This fact leads at the variation of the microstructure and fine ...

    • XRD Analysis in Front of a Corrosion Crack Tip 

      Gheorghieș, C.; Levcovici, S.; Păunoiu, V.; Gheorgieș, L.; Oancea, C.; Ostache, I.; Alexandru, P. (Universitatea "Dunărea de Jos" din Galați, 2008)
      During exploitation of the heat exchangers some damages can appear in the contact region between the gaskets and the stainless steel walls. The studies upon the material were performed using SEM microscopy, X-ray ...
