ANALYSIS OF COATED STEEL SHEETS’ RESISTANCE TO CORROSION AFTER PLASTIC DEFORMATION

Abstract

The automotive industry is influenced by customers’ requests, including safety and lifetime improvement, weight and emissions decreasing. The paper presents corrosion resistance improvement of car-body components by steel sheets coated with Zn-Al-Mg coating. Specimens coated with GI and Zn-Al-Mg coatings have been deformed by stretching (Erichsen test) and 3-point bending tests to 90 and 180. After deformation they have been tested in aggressive corrosion atmosphere of salt spray in corrosion chamber. Reached results showed better corrosion resistance of Zn-Al-Mg coatings when compared to standard Zn coating GI.
