Trends in ground bed design for cathodic protection of underground structures

CATHODIC protection of underground structures for the mitigation of corrosion to those structures has long been an established means for controlling corrosion. It is interesting to note that this paper deals primarily with a relatively new technique in the field of corrosion, proposed originally by the man given credit in “Who's Who” for the development of cathodic protection. This man, Mr. R. J. Kuhn, a consulting engineer in New Orleans, La., has made several contributions in the field of corrosion control. The original idea of cathodic protection is one of impressing a direct current in such a way as to counteract the tendency of the galvanic or man-made electric currents which tend to leave the underground structures, thereby counteracting the loss of metal through the electrochemical process known as corrosion or electrolysis.
