Valores de la constante B del método de resistencia de polarización para veinte sistemas metal-medio diferentes

In a research about the possibilities of the on-site application of electrochemical techniques, the methods of polarization resistance and intersection were utilized on small metal specimens in lab studies as contrast procedure. The tests encompassing 20 different metal-environment systems, covering a wide variety of environments resistivities and corrosion resistance of metallic material. A compilation of the Tafel slopes for all the considered systems is given, which enables to obtain a small catalog of constant B in the Stern-Geary formula ( i corr = B/R p ).
