Experiments were done with two levels of electrode diameters. Average localized corrosion rates and maximum pit-depths were monitored over time. Coupons of 17-4PH and GTD450 stainless steels were placed in the same environment to compare the results with that of CMEAS probes.

Coupled Multi-Electrode Array Sensor (CMEAS) have been used for monitoring performance of 17-4PH stainless steel under Salt-fog conditions. Temperature, pH and Salt-concentrations and pH were varied at 2 levels for understanding the effects of these parameters on localized corrosion performance. Specific sets of experiments were done with also two levels of electrode diameters. Average localized corrosion rates and maximum pit-depths were monitored as a function of time. Coupons of 17-4PH and GTD450 stainless steels were also placed in the same environment to compare the results with that of CMEAS probes. A transfer function was developed between the pit-depths as provided by the instrument and the experimental variables. It was also noted that the correction factors for calculating maximum pit-depth based on CMEAS output needs to be further modified in order to correlate the same measured by the exposure to that of the exposure coupons.

Key words: conference papers, 2017 conference papers, CMEAS, Pitting, Salt-fog, 17-4PH, GTD450, Stainless Steel, Probes, LC maximum pit-depth, Nanocorr

The corrosion process of carbon steel in the presence of silica sand deposit in chloride-containing solution at 30 °C was monitored by use of electrochemical noise (EN). Results demonstrated that electrochemical noise with recurrence quantification analysis is useful for monitoring localized under deposit corrosion.
