Abstract

The paper is focused on the part of complex work dealing with verification of functionality of non-destructive technique of electrochemical noise applied on HDG steel sheets samples with different surface treatment, namely on samples to be treat with Cr3+, anticorrosion oil and non-oiled and non-passivated ones. Besides monitoring of quality of surface treated zinc sheets (activity/passivity) by ENA technique an extension of corrosion deterioration was quantified gravimetrically after 3, 15, 22 and 30 days of exposure in 3 % NaCl, 3% ecological salt mainly composed of MgCl2, CaCl2 and condensation chamber. Corrosion products were observed with support of SEM microscopy with EDX analysis.
