Regression Equations for Predicting the Corrosion of Steel

Abstract

Regression analysis was applied on the results of corrosion experiments performed on two grades of steel exposed to the laboratory atmosphere and 0.1M solutions of sodium chloride, ammonium hydroxide and hydrochloric acid. The regression equations showed acceptable coefficients of correlation between experimental and calculated extents of corrosion; indicating that the derived equations are applicable within the range of experimental values utilized.
