1. A method of providing cathodic voltage controlled electrical stimulation comprising:
providing a metallic object to be treated that serves as a working electrode;
applying a polarization scan to the metallic object to be treated;
using a processor, autonomously detecting a hydrogen evolution reaction threshold from the polarization scan to determine a cathodic voltage to be applied to the object to be treated wherein the processor is programmed to detect specific inflection points in the applied polarization scan in order to precisely detect the cathodic voltage; and,
applying the determined cathodic voltage to the metallic object to be treated, wherein the method further comprises:
initiating the polarization scan at an open circuit potential and scanning cathodically to a target voltage that enables the detection of the hydrogen evolution reaction by the polarization scan, followed by analyzing the polarization scan in real time; and
detecting a first change in slope in the polarization scan indicative of an oxygen reduction reaction prior to detecting the second change in slope in the polarization scan that indicates the hydrogen evolution reaction.
