摘要

The Rotating Cage (RC) system is a well-known laboratory tests methodology to evaluate the materials corrosion resistance and inhibitors under flow conditions, but does not allow to perform electrochemical measurements. The adaptation of the conventional RC to an Electrochemical RC in Autoclave (ERCA) allows following the corrosion process, as well as the performance of the corrosion inhibitors throughout the immersion time. The specimens tested can be monitored by impedance measurements, linear polarization resistance and polarization curves. The results presented herein shows that with ERCA assembly was possible estimate correctly the inhibitor efficiency and the influence of inhibitor concentration by electrochemical data once similar efficiency values were obtained by corrosion rates estimated from weight loss measures. It was possible to track the inhibitor action, film forming and consequent increase on X65 polarization resistance at 0.16% NaCl, 8.5 bar of CO_2 in 170 Bar of total pressure, rotation speed of 540 RPM.
