    • The Conservability of Old Wood at the Contact with Metallic Structural Components from Artifacts 

      Sandu, Ion; Vasilache, Viorica; Hayashi, Mikiko; Vrânceanu, Narcisa; Ciocan, Adelina; Sandu, Andrei Victor (Universitatea "Dunărea de Jos" din Galați, 2008)
      The paper presents the impact of metallic pieces being in contact with wood, as structural elements, used in obtaining artifacts. The paper studies, based on old samples, the reciprocal effect obtained at the wood-metal ...

    • The Influence of Cold Rolling on the Mechanical Characteristics for Drawing Steels 

      Potecaşu, Octavian; Potecaşu, Florentina; Alexandru, Petrică; Radu, Tamara (Universitatea "Dunărea de Jos" din Galaţi, 2008)
      The paper presents the changes of the mechanical and technological characteristics of steel for deep drawing, cold rolled and recrystallization heat treated. The research was conducted on samples taken from cold rolled ...

    • 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 ...

    • 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 ...
