“…Values of the empirical parameters A and B for the investigated steel samples are very well matched with the data given in the literature, and this constant depends on the electrolyte temperature [22,23]. Figure 6 and Table 5 show the influence of the potential scan rate on depassivation of stainless steel in 0.5 mol dm -3 NaCl.…”

“…Constant A is essentially the actual depassivation potential (v = 0 mV s -1 ), while B is the time needed for the induction of pitting corrosion. According to the literature numerical values of this constant depend on the electrolyte temperature [22,23]. The parameters A and B of the investigated samples increase in order: AISI 304 AISI 316L duplex steel.…”

“…Stainless steel is highly conductive and stable electrochemically in neutral or mildly acidic or basic aqueous solutions. 46,47 Different parts of a pin (the head, the shaft and the sharp tip) can be used for different purposes: the head can serve as an electrode in omniphobic paper-based devices, part of the stem can serve as an electrode in thread-based devices, the stem can be used for connection to the potentiostat, and the sharp tip can be used to anchor the pins in a mechanical support.…”

This work describes the adaptive use of conventional stainless steel pins-used in unmodified form or coated with carbon paste-as working, counter and quasi-reference electrodes in electrochemical devices fabricated using cotton thread or embossed omniphobic R F paper to contain the electrolyte and sample. For some applications these pin electrodes may be easier to modify and use than printed electrodes; their position and orientation can be changed as needed, and the electrodes can be washed and reused between multiple devices. Electroanalytical devices capable of multiplex analysis (threadbased arrays or 96-well plates) can easily be fabricated using pins as electrodes in either thread or omniphobic R F paper.

“…En los pH 6 y 7,5 Figura 5b y 5c los valores de potencial de picadura Ep son similares, por tanto en estas condiciones el pH no influye en el potencial de picadura lo que está de acuerdo a lo reportado por diferentes autores acerca de la corrosión en este tipo de acero inoxidable [16], [17]. En el caso de pH de 10 hay una leve disminución de Ep, la cual se puede atribuir a un favorecimiento en la cinética de formación de la película pasiva, por la presencia de OH -durante el proceso de polarización anódica [18].…”

RESUMENSe estudió el efecto del pH en el comportamiento de la corrosión del acero inoxidable 316 LVM y la aleación de Ti6Al4V ELI mediante técnicas electroquímicas, como Polarización Potenciodinámica Cíclica y Espectroscopia de Impedancia Electroquímica. La velocidad de corrosión se calculó por extrapolación de las pendientes Tafel y se analizó la susceptibilidad a las picaduras de cada uno de los materiales sometidos a condiciones de concentración de 3% de NaCl y un amplio rango de pH (4,5-6-7,5-10-12). Los resultados obtenidos indicaron que las condiciones de pH 4,5 tienen un efecto negativo en la velocidad de corrosión de ambos materiales comparado con los otros pH.Palabras clave: Velocidad de corrosión, susceptibilidad a la picadura, impedancia electroquímica, polarización potenciodinámica cíclica, biomateriales. . The results exhibited that the conditions of pH 4,5 has negative effect in the corrosion rate for both materials compared with other pH. ABSTRACT The effect of pH on corrosion behaviour in stainless steel 316 LVM and alloy Ti6Al4V was studied by various electrochemical techniques such as cyclic potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The corrosion rate was calculated with Tafel extrapolations and the pitting corrosion was also analysed for each material in different conditions of concentration 3% of
