Prediction at Long Terms of the Atmospheric Corrosion of Structural Steels from Short-Term Experimental Data

Source

Two experimental laws expressing the relationship between the weight losses and the time of exposure allow a fair assessment of the corrosion evolution of steels in numerous sites. The simultaneous existence of these two laws implies intercorrelation between the coefficients of the empirical equations.

The effects of the climatic and pollution factors on these coefficients are discussed.

It is suggested to represent the corrosiveness of a test site toward a steel grade by the one-year weight loss and the further evolution of corrosion as a function of this weight loss and the relative humidity of the site.
