I did a science fair project on protecting iron from corroding using a sacrifcial anode of zinc(obtained from pennies - very inexpensive!). When I used copper with iron it accelerated the corrosion of the iron because copper is more cathodic than iron. Can I cause copper to develop a patina(corrode) by creating a sacrifical anode between the copper and a more cathodic metal? If so, which metal would I use?
