Corrosion is a concern for the oil industry. According to the NACE, this phenomenon can cause problems that cost millions of dollars annually, putting people and the environment at risk. To combat this phenomenon, corrosion-reducing control practices must be implemented. It must be measured with sensitive tools and equipment. As a result, the current study proposes creating a laboratory prototype with the primary goal of simulating the dynamic operation of the rotating cylinder electrode (RCE). A rotating cylinder electrode (PRCE) laboratory prototype is constructed using an experimental methodology based on RCE physical-mechanical characterization, mathematical modeling of its actuators (brushless motors), and electronic instrumentation. This methodology enables the design and implementation of a control system to manipulate the rotation speed of the RCE stem in the evaluation of electrochemical noise, allowing for the rejection of external disturbances and the monitoring of references in a turbulent flow. The PRCE's control section's design, when compared to currently available equipment, allows for cost, acquisition, and maintenance savings (RCE). Following that, the correct design of the PRCE prototype will be validated.

The present work is an electrochemical evaluation of hydrotalcite Mg/Al impregnated with caffeine for the protection of the AZ31 alloy, where different concentrations of the inhibitor were evaluated to determine the best result in order to be applied as a coating in orthopedic uses. The efficiency of the hydrotalcite coating as a function of concentration was determined using electrochemical impedance spectroscopy and it was shown that HT MgAl with 5 ppm perezone impregnated achieved 99% inhibition efficiency.
