Descripción
From the corrosion point of view, hydro power should be a very active field, since large metallic structures are exposed to an aqueous environment. However, based on long term experience, designs are robust and significant corrosion of turbines is excluded to a high degree. Nevertheless, sometimes, unexpected cases of corrosion of turbine components are experienced, which cannot be related to the chemical parameters of the water alone, but may be explained by considering microbial activity.
