Explains the technique of cathodic protection in conjunction with the galvanic series of metals and cell action, plus the history and development of cathodic protection. Touches upon thermodynamic considerations, and uses polarization curves to explain the rates of corrosion reaction and how these rates can […]

A few years ago the word “corrosion” was not used with familiarity by most of those people charged with the maintenance of underground plant facilities. Rusting usually manifested itself in “red water” problems. Pitting in boilers was recognized as a treatment inadequacy. Leaking in underground […]

Soil bears the greatest responsibility for underground corrosion losses, and the difference in corrosion losses of different types of ferrous materials when in contact with the soil are very small indeed. DOWNLOAD PAPER

Cathodic protection techniques provide a direct means of stopping metal loss due to stray earth currents. The method ensures long life and reduced maintenance for buried equipment. DOWNLOAD PAPER

Recent work has made possible the application of anodic protection techniques to metals in active chemical environments. One outcome of this research is strong evidence to suggest that mild carbon steel and low alloy stainless steel can be rendered almost inert to severely corroding environments. […]

Since aqueous corrosion is electrochemical in nature, it is logical that electrochemical techniques can be used in its control. The electrochemical corrosion cell is made up of four essential components: the anode or electrode at which oxidizing processes take place and usually corrosion; the cathode […]

The ground (soils) does not confine electrical current to discrete paths in the same way as electrical cables do. It is meaningful to talk about the resistance per foot of a copper wire, but not meaningful to talk about the resistance per foot of a […]
