Corrosion








Corrosion occurs in all metals at some time





Room temperature oxidation, the most common form, is

most obvious in mild and low-alloy steels. The process is

accelerated dramatically by comparatively small

amounts of contaminants found in the paper making

process.






When exposed to high temperatures, metals will almost

invariable result in oxidation of metal surfaces.





Chemical corrosion is the result of attack by acids or

alkaline compounds which dissolve the metal surface.





Electrolytic corrosion occurs when two metals in contact

with each other have different electrode potentials. It is a

major contributor to most of the corrosion found in steels.






By virtue of its environment the


paper machine is prone to


corrosion.
