Surface corrosion

If this occurs across the entire surface at more or less the same speed, experts refer to this as surface corrosion. In the process the material is eroded practically evenly. (fig. 1)

Surface corrosion is regarded by experts as the "nicest form" of corrosion, as it is calculable. The rate of erosion is known for many corrosion systems. The average progression of corrosion for components – and therefore their lifetime – can therefore be estimated. As a rule, surface corrosion is triggered by aggressive substances such as oxygen, salts or acids.
