or another metal is displaced from the medium at the surface of the 

 metal. In either case reaction products appear and usually exert a 

 controlling influence upon the progress of attack. In the replacement 

 type of corrosion process, in which the attack occurs by means of the 

 operation of small galvanic couples at the surface of the metal, it is 

 possible to consider separately those influences which affect anode 

 behavior and those involved in cathode behavior. The course of 

 corrosion or resistance to corrosion may be explained in terms of the 

 anode or cathode control of the process. It is apparent then that a 

 knowledge of both the composition and condition of a metal surface 

 and of the surrounding environment is requisite to an understanding 

 of corrosion problems.
