Abstract
This paper outlines the tendency and prevention measures of corrosion which occurs on water-cooling units (such as heat exchangers and coolers) of electrical equipment. Materials such as steel, phosphor deoxidated copper, brass, cupro-nickel, titanium, and stainless steel are treated in such corrosion environment as fresh water and sea water to investigate some factors including water quality and flow velocity. Corrosion resistance of phosphor deoxidated copper is stable in the fresh water but is unstable in the sea water. So phosphor deoxidated copper should not be used in the sea water. Brass shows relatively good corrosion resistance in the sea water, but stress corrosion cracking easily occurs in the fresh water, which sometimes causes destructive results. When the water is circulated in steel piping, unique corrosion sometimes occurs due to microorganisms. In this case, it is effective to improve water quality by adding disinfectants. Stainless steel forms a passive-state membrane and shows stable corrosion resistance. However, since the membrane is destroyed by chloride, local corrosion may occur in the sea water. Therefore, stainless steel that is not for the use in the sea water should not be used. 3 refs., 4 figs., 4 tabs.
