Corrosion and Materials Degradation, Volume 3, Issue 1

2022 March - 9 articles

Cover Story: ZnAl coatings are used for corrosion protection in a variety of applications, including offshore, where the corrosive attack of seawater is superimposed by mechanical loads such as wind or waves. The corrosion fatigue behavior of mechanically post-treated ZnAl4 coatings on S355 J2C + C substrates was investigated in 3.5% NaCl under simultaneous cyclic loading. The spraying process and mechanical post-treatment by machine hammer peening (MHP) result in different coating properties, which influence both the fatigue and corrosion properties. The ZnAl coatings provided an adequate corrosion protection. MHP post-treatment improved the corrosion fatigue behavior in the high cycle fatigue regime with an increase in stress amplitude.
