Abstract

This study revealed the cracking activity due to brittle phases in the hot dip Zn-Al-Mg coating.Higher Al content and Ni addition enabled to refine interfacial layer and modulated the evolution of brittle MgZn2 phase.Increasing cooling rate of the coating promoted the microstructural refinement.The advanced Zn-Al-Mg alloy coating exhibited better combination of improved cracking and corrosion resistance.
