“…Considering the full duration of an EN measurement, some DC drift is visible in the raw data. The determination of which part of the data can be regarded as DC drift is however not straightforward [55]. Therefore, it is likely that some DC drift will remain in the data after removal, and hence influence the calculation of Rn and Rsn.…”

RESUMEN:La medida e interpretación del Ruido Electroquímico (REQ) es uno de los métodos de análisis utilizados para la interpretación del fenómeno de la corrosión. Presenta, frente a otros tipos de metodologías, una serie de ventajas como son su sencillez, bajo coste y el hecho de ser un método no perturbativo. Esta metodología se ha mostrado eficaz en el estudio de sistemas metal desnudo-electrolito combinada con otras técnicas de análisis. En este caso se aplicó al estudio de pinturas comerciales utilizadas en procesos de prevención de la corrosión de las que no se tenían otro tipo de información. Como principal resultado de este estudio se muestra la eficacia de la aplicación de la resistencia de ruido, ya verificada en ensayos a nivel de laboratorio, para explicar el comportamiento de sistemas de pinturas que actualmente se están utilizando en la industria. ABSTRACT:Noise resistance applied to the study paints. Electrochemical noise is one of the methods of analysis used to interpret the phenomenon of corrosion. It has a number of advantages over other methodology types including its simplicity, its low cost and the fact that it does not disturb the system. This methodology appears to be effective together with other techniques in metal-electrolyte systems. In this case the technique is applied on its own on commercial anti-corrosion paints for which no information is available from other techniques. The main result of this study reveals the effectiveness of the noise resistance parameter, which had already been tested in the lab, when it is used to explain how the paint system behaves in industry.

The simplicity of measuring equipment and versatility of data analysis makes electrochemical noise measurement an ideal technique for acquiring electrochemical information about the corrosion behavior of a painted metal relatively quickly. Hence the method has great potential for use in the laboratory as well as in field situations. However, special care must be taken in choosing data acquisition parameters, reference electrodes and symmetry of electrodes in order to achieve reproducible measurements. These areas have been discussed in this review along with methods of data analysis, alternative electrode configurations for on-site measurements and novel applications of the technique. AbstractThe simplicity of measuring equipment and versatility of data analysis makes electrochemical
