Corrosion Behaviour of Automotive Steel Sheets Depending on the Degree of Deformation

Abstract

This paper presents the results of research aimed to measuring the corrosion properties of automotive steel sheets. The degree of deformation influence to the corrosion properties of the steel sheet for car body parts has been proven by the modern methods of corrosion monitoring such as Electrochemical Impedance Spectroscopy. Corrosion rate was assessed using electrochemical methods in 0.1 M solution of NaCl. Experimental studies have pointed out if degree of deformation increases the corrosion rate of the steel sheet increases as well.
