Abstract
The effect of IB element additions [Ag] on the corrosion behavior of AlZn alloy has been investigated. The potentiodynamic polarization curves revealed that the corrosion behavior of SS Al , SS Zn and AgZn 3 phases was significantly influenced by IB element content. The electrochemical investigations showed that the corrosion rate increased with the IB-element additions. Furthermore, it was also evidenced the formation of a passive layer for the highest Ag content alloys; the passivity of this layer could be broken due to the presence of the intermetallic compound (IMCs) AgZn 3 .
