Question

I am attempting to conduct a research project comparing the effect of various current levels on electrolytic rust removal. Somewhat ironically however, I need a way to induce corrosion in a predictable and fast manner so as to have a standard baseline from which to conduct my experiment. Ideally it would somewhat resemble natural corrosion so that the data is applicable outside of a laboratory setting. Thank you in advance to anyone who answers.

Answer 1

To induce corrosion for your research project, you can simulate natural corrosion by immersing the metal in saltwater or by damaging its protective coating.

Step-by-step explanation:

In order to induce corrosion in a predictable and fast manner for your research project on electrolytic rust removal, you can simulate natural corrosion by subjecting the metal to conditions that accelerate the oxidation process. One way to do this is by immersing the metal in a saltwater solution, as salt water speeds up the corrosion process due to the ions forming a salt bridge between the anodic and cathodic sites.

Another method is to scratch or otherwise damage the protective coating of the metal, which allows oxygen and water to come into contact with the metal surface and accelerate corrosion.
