The aim of this work is the analysis of the hot dip zinc coated steel plates mechanical properties by means of a traditional four-point bending test, performed on coated specimens at three different bending angles. Results are analysed both in terms of mechanical behaviour and phase damages of coatings. The influence of the chemical composition of zinc baths is correlated to intermetallic phase formation and their damages. It is found that, depending on the bath composition, the different phases can form in different amounts, influencing the mechanical behaviour of the coating.

Abstract

The aim of this work is the analysis of the hot dip zinc coated steel plates mechanical properties by means of a traditional four-point bending test, performed on coated specimens at three different bending angles. Results are analysed both in terms of mechanical behaviour and phase damages of coatings. The influence of the chemical composition of zinc baths is correlated to intermetallic phase formation and their damages. It is found that, depending on the bath composition, the different phases can form in different amounts, influencing the mechanical behaviour of the coating.
