Electrochemical and Mechanical Changes on Fatigue Corrosion Damaged Surfaces

Abstract

The paper presents some surfaces changes aspects in fatigue corrosion damage based on electrochemical, mechanical profilometry and microscopically analyze of cylindrical and plate steel specimens. The researches have demonstrated that principal cause of damage for rotating specimen is localized pitting corrosion and for plate specimen is generalized surface corrosion, manifested by oscillatory evolution of electrochemical parameters
