What is the difference between oxidizing and corroding?
I am no chemical engineer but I think oxidation is primarily a result of being in contact with the atmosphere over an extended time period. Corrosion, to my way of thinking, is the actual destruction of the material due to any number of factors. Consider a penny before 1984 (mostly copper instead of copper plated zinc now). A penny will eventually actually disintegrate if left fo lie outside in the dirt.....it may take years but it will happen. With a silver coin (90% silver, 10% copper) the coin will turn black in color but won't decay as much as purer copper. I believe also that copper loses its conductivity over time whereas I read somewhere that silver will not.
