How can I accelerate iron corrosion in a way that simulates natural processes?

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.
