If i'm testing the rusting rate of iron, and the washer i use isn't pure iron? How does the rusting differ?

If i'm testing the rusting rate of iron, and the washer i use isn't pure iron? How does the rusting differ? I need good information for my science fair.


Hurry please :)If i'm testing the rusting rate of iron, and the washer i use isn't pure iron? How does the rusting differ?
I am not sure exactly what happens for each metal, but i do know that metals rust at different rates (ex. gold and silver does not rust, but iron certainly does)


depending on the other metal and the ratio of the metals, the washer could rust much more slowly or much faster
