Abstract

The present study investigates the influence of temperature on corrosion of AM SS316L in CO2 saturated brine solution. As the temperature increased from 25 degrees C to 70 degrees C, the corrosion rate rose nearly fivefold, from 1.78 to 10.06 mpy. The pitting potential decreased from 818 mV to 450 mV, with the gap between |Epit - Erep| widening from 669 mV to 853 mV. EIS results corroborated these results, revealing a decline in R-ct from 4755 to 858 Omega cm(2) and an increase in Y-ct from 38 to 119 s(n)Omega(-1)cm(-2). Subsequent surface morphology analysis post-corrosion testing revealed increased corrosion severity with rising temperature. In summary, elevated temperature led to increased corrosion rates, more susceptibility to pitting corrosion, and hindered repassivation.
