“…Electrochemical noise can be characterized by common statistical parameters such as the mean, the variance and the standard deviation; in particular the use of the potential/current standard deviations can be done separately, either by its quotient. Called noise resistance (Rn), in the expression (2) it is calculated as the quotient between the standard deviations of the potential over current records (Sánchez et. al., 2005;Bertocci et.…”

“…Los progresos recientes en el desarrollo de nuevas téc-nicas analíticas han ayudado a ampliar el conocimiento de los procesos superficiales e interfaciales ligados al fenómeno y a una mejor caracterización de los productos de corrosión que se forman [7][8][9][10] . Pero, más que un camino, la corrosión es un laberinto de gran complejidad, esquiva a las generalizaciones y modelos.…”

“…Durante el siglo que acaba de extinguirse, se dieron muchos e importantes pasos hacia la comprensión de este tipo de corrosión. Existe mucha información sobre la corrosión atmosférica de los metales, obtenida de forma independiente por distintos investigadores, en diferentes partes del mundo y, en el último decenio, se han llevado a cabo diversos estudios de colaboración, en los que ha intervenido un elevado número de países [1][2][3][4][5][6] .Los progresos recientes en el desarrollo de nuevas téc-nicas analíticas han ayudado a ampliar el conocimiento de los procesos superficiales e interfaciales ligados al fenómeno y a una mejor caracterización de los productos de corrosión que se forman [7][8][9][10] .

“…Unlike other in-situ electrochemical techniques, such as polarization curves, EIS, etc., which may lead to an alteration of the process under study due to perturbation, EN needs no externally imposed perturbation and can be conducted under open circuit conditions. 7 Ever since the first EN investigation in corrosion by Iverson in 1968, 8 EN has been widely used to study the corrosion of various metallic materials, such as stainless steel, 9-12 aluminum, [13][14][15][16] organic coated plate [17][18][19][20][21][22] and reinforcement steel. [23][24][25][26] Noise resistance is defined as the ratio of the standard deviations of potential noise to the standard deviation of current noise.…”

ABSTRACTThis paper investigates the application of Electrochemical Noise (EN) to study the corrosion behavior of 304 nuclear-grade (NG) stainless steel (SS) in high purity water system at varying temperatures (105, 160, 190, 220, 250, 293°C) and pressures (0.6,7,9, 10.5,16, 19 MPa). An EN sensor has been developed and applied to the high temperature water system.
