Abstract

MAGANA-ZAVALA, C.R.; RODRIGUEZ-GOMEZ, F.J.; ACOSTA, D.R.  and  AVILA-GODOY, R.. Estudio del comportamiento ante la corrosión de películas delgadas de Ni y óxido de Ni obtenidas por espurreo catódico frente a un medio amargo. Rev. mex. fis. [online]. 2005, vol.51, n.6, pp.596-599. ISSN 0035-001X.

The aim of this work is to study the behavior of nickel and nickel oxide thin films obtained by cathodic sputtering on steel AISI 1018 (UNS G 10180), with the purpose of diminishing the corrosion rate of low carbon steel when it is exposed to a sour medium (sulphidric acid and chlorides) and to extend the life of metallic petrochemical structures which would result in an important amount of monetary and human resources savings. The characterization of the surfaces was carried out by electrochemical techniques, such as polarization curves and electrochemical impedance spectroscopy.

Keywords : Nickel; cathodic sputtering; sour medium.
