Manufacture of Stud Link Chain Cable Made of Grade U1 and U2 Steel Drăgan, Viorel; Bordei, Marian; Chis, Chris Mircea We have analyzed the fabrication technology of the link chain cable made of grade U1 and U2 steel from TREFO S.A. Galati and we had in view during the experiments several rolling programs. The main characteristics of a product quality, material or working process can be classified into the following groups: technological and contractual. Further on, we are going to present data regarding the link chain cable where samples were drawn, micro metallographic analysis referring to grade U1 and U2 steel and the characteristic obtained on the same areas where the metallographic analysis were made.

Study of the Thermodynamic Regime at the Continuous Casting of Steel Ivănescu, Alexandru; Ivănescu, Lilica; Cireșica, Cocindau; Munteanu, Viorel The paper presents the evolution of the heat exchange coefficient along the path of the continuous casting unit, as a function of the cooling water flow rate and the path length. The optimization of this thermodynamic regime assures the improvement of the quality of the continuous cast slabs and the increasing of the rate of obtaining the qualitatively corresponding slabs.

Multifunctional ZnO-Based thin Films by SOL-GEL Method Mușat, Viorica; Fortunato, Elvira The paper presents the crystalline structure, morphology, optical transmittance, electrical properties and room temperature photoreduction-ozone oxidation properties of some Al-doped ZnO thin films prepared by sol-gel method. The investigated films are high transparent (85-95% within the visible and near IR wavelength region), high conductive (2.9 10-3 Ω cm) and have a reversible photoreduction-oxidation response.

Studies About Electrochemical Plating with Zinc-Nickel Alloys Gutt, Gheorghe; Vasilache, Violeta; Poroch-Serițan, Maria; Vasilache, Traian The electrochemical deposition of zinc and combinations with elements of the 8th group of the Periodic System (nickel, cobalt, iron) have good properties for anticorrosive protection, compare with pure zinc. For steel pieces, these films delay apparition and formation of white and red iron oxide. We used solutions with different concentrations of zinc chloride, nickel chloride and potassium chloride. For analyze the results we utilized the optic microscope and the X-ray diffraction. THE ANNALS OF “DUNAREA DE JOS” UNIVERSITY OF GALATI. FASCICLE IX.
