Influence of open circuit potential time on the corrosion behavior of heat treated AZ80 magnesium alloy
Abstract
The main aim of the paper is to provide findings about the influence of open circuit potential (OCP) time on the corrosion behavior of heat treated AZ80 magnesium alloy in an aggressive chloride environment. Corrosion characteristics of the as-cast, as-extruded and exruded + heat treated state were obtained by potentiodynamic polarization tests (PDP) at the laboratory temperature in 0.1 M NaCl solution. Additionally, a study of the microstructure was carried out using optical microscopy and the analysis of individual phases was performed by thermodynamic calculations in the equilibrium state. Longer OCP time leads to the formation of a passive layer that improves corrosion resistance of the substrate.
