Temperature

Temperature can have a significant effect on the corrosion of metals, with increased rates of corrosion as temperature is increased. Temperature may also affect the form of attack that the corrosion takes on; for example, changing the temperature may change the corrosion mechanism from uniform to pitting. It can also evaporate condensed moisture on metallic surfaces leaving behind corrosive contaminants. High temperatures can produce a form of corrosion where gas becomes the electrolyte as opposed to a liquid medium.
