Uso de técnicas electroquímicas para determinar la resistencia a la corrosión localizada de un acero inoxidable súper dúplex UNS S-32760

ABSTRACT Super duplex stainless steel UNS S-32760 is one of the most commonly used alloys in several industrial applications, due to its high corrosion resistance. However, this characteristic is affected when the alloy is exposed to aggressive environments. In this work, the effect of temperature on the critical potential of super duplex stainless steel was studied through the implementation of electrochemical techniques such as Cyclic Potentiodynamic Polarization (CPP), and Potentiodynamic-Galvanostatic-Potentiodynamic Polarization (PD-GS-PD) at 25°C,60°C and 80°C in 3.5% w/w NaCl solutio...
