Both the cavitation erosion and marine corrosion behavior of the arc-sprayed coatings were evaluated, and compared with the conventional anti-corrosion paint. In terms of marine
The fundamental cause or driving force for all corrosion is the lowering of a system’s Gibbs energy. As Fig. 1 illustrates, the production of almost all metals (and engineering components made of metals) involves adding energy to the system. As a result of this uphill thermodynamic struggle, the metal has a strong driving force to return to its native, low energy oxide state. This return to

Carbonation of concrete is another cause of steel cor-rosion. When concrete carbonates to the level of the steel rebar, the normally alkaline environment, which protects steel from corrosion, is replaced by a more neutral environment. Under these conditions the steel Quality Concrete—Concrete Practices The first defense against corrosion of steel in concrete is quality concrete and

3.2 MARINE ENVIRONMENTS. Corrosion resistance depends on the position of the metal with respect to the sea. It can be immersed, semi-immersed or placed at a certain level above the water. In each case, the environment is different, depending on the exposure, and consequently, the corrosion resistance of the metal may be different. 3.2.1 Exposure to marine atmosphere. This is the case of …
