The effect of strain amount on corrosion behavior of EDDQ steel sheet

This paper presents the results of research aimed to measuring the corrosion properties of EDDQ steel sheet. The strain amount influence to the corrosion properties of the steel sheet for drawn 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 strain amount increases the corrosion rate of the steel sheet increases too.
