    • Coating of the Lasting Moulds with Hard Alloys 

      Dima, Ovidiu (Universitatea "Dunărea de Jos" din Galați, 2010)
      This paper presents the researches on the welded coating of lasting moulds used for casting at high melting temperatures. It shows that the coating through the flux welding with the addition of metal powders and graphite ...

    • Corrosion Behavior of Ni-P Coated Steel Strips 

      Istrate, Gina Genoveva; Radu, Tamara (Universitatea "Dunărea de Jos" din Galați, 2015)
      In addition to high hardness, Ni-P coatings obtained by the electroless method are widely used due to their high corrosion resistance. The corrosion resistance depends on the content of phosphorus in the coating. Various ...

    • Corrosion Behavior of Zinc Alloy Layers 

      Radu, Tamara; Ciocan, Anisoara; Istrate, Gina Genoveva (Universitatea "Dunărea de Jos" din Galați, 2014)
      The alloying of zinc with some additional elements in specific quantities could be reliably used in the hot-dip coating process. These elements conferr substantially improved performance to the end-product specially by ...

    • Fabrication and Characterization of Cobalt/Iron Composite Coatings 

      Gheorghieș, Livia (Universitatea "Dunărea de Jos" din Galați, 2013)
      Cobalt/iron composite coatings are used in micro-equipments due to their high magnetic saturation values and Curie temperatures, as magnetic nanoparticles capable of killing cancer cells, for magnetic data storage and ...

    • Hardening of the Grey Cast Iron Through the Vibrating Electrode Method Using a WC Electrode and in Combination with Ti Electrode 

      Perju, Manuela Cristina; Nejneru, Carmen; Răileanu, Tudor; Axinte, Mihai; Hopulele, Ioan (Universitatea "Dunărea de Jos" din Galaţi, 2008)
      There have been tested samples of grey cast iron, the hardening being made through WC coating through the vibrating electrode method with a layer, two layers and through double layers combined with Ti and TiC. Besides ...

    • Nanocomposite Coatings Obtained by Electro-Co-Deposition of Inert Particles with Cobalt-a Review 

      Şorcaru, Florentina Simona; Benea, Lidia (Universitatea "Dunărea de Jos" din Galaţi, 2012)
      The paper focuses on review investigations of electrodeposition processes of metallic coatings containing dispersed nanosized particles. The nanosized particles, suspended in the electrolyte by agitation and/or use of ...

    • Silica thin Films Obtaining by Sol-Gel Dip Coating with Controlled Optical Properties 

      Mihoreanu, C.; Eneșca, A.; Duță, A. (Universitatea "Dunărea de Jos" din Galați, 2014)
      Transparent oxide films are widely employed as antireflection or high reflection coatings, band-pass filters and narrow-band-filters in various optical and electronic devices. The performances of these devices are based ...
