    • The Influence of the Thermomagnetic Treatments on the Hardness Number of Steels and the Superficial Layers Nitrided Durability 

      Papadatu, Carmen Penelopi (Univeritatea "Dunărea de Jos" din Galați, 2005)
      Two types of steels subjected to a nitriding thermo-chemical treatment after thermomagnetic treatments. The structural aspects into superficial layer of these steels are studied during friction process by using of an ...

    • The Properties of Hardened Lead 

      Potecașu, Florentina; Potecașu, Octavian; Drugescu, Elena (Universitatea "Dunărea de Jos" din Galați, 2005)
      Lead hardened through oxide scattering is investigated as raw materials for the fabrication of the support gratings of lead accumulators in order to increase their life service. For the preparation of lead powder hardened ...
