Corrosion is a chemical reaction to which even the strongest structures fall victim. Metals such as steel react with oxygen and water, going on to rust and decay. Cathodic protection plays a key role ...

A 1998 EPRI study, released in October of 2001, estimated the cost of corrosion in 1998 to steam generating facilities alone at $5.37 billion. The study, EPRI Report 1004662, also concluded that 22 ...

As Rocky bounded toward the Philadelphia Art Museum, the steps below his feet were already in decay. You couldn’t see it in that inspirational scene of the classic 1976 boxing movie, but the steel ...

During the 2005 National Electrical Code (NEC) review cycle, a relatively simple revision was made that created a significant change on the cathodic protection (CP) systems of petroleum and chemical ...

This corroding galvanized steel pole exhibits red corrosion products due to corrosivity of soil, chloride ions and galvanic action. When Dawson Public Power District in Lexington, Nebraska, U.S., ...

This article summarises the international development of cathodic protection of steel in concrete. The technology was developed in Europe and the USA for applications to buried prestressed concrete ...

Cathodic corrosion protection is widely used, but how it works exactly has been unclear and disputed by experts. ETH researchers propose a mechanism that resolves the apparent contradictions between ...
