Changes in Corrosion Behaviour of Zinc and Aluminium Coatings with Increasing Seawater Acidification.

The increase in greenhouse gas emissions has led to seawater acidification, increasing the corrosion rate of metal structures in marine applications. This paper indicates that the spraying of four types of coatings, namely Zn, Al, Zn-Al, and Al-Mg, using the arc-spraying technique on steel substrate S235JR, creates effective protective coatings that interact differently with various pH solutions exposed to varying levels of seawater acidification. The study analyses the structural properties of the coating materials using SEM and XRD techniques.

Effect of APS Spraying Parameters on the Microstructure Formation of FeAl Intermetallics Coatings Using Mechanochemically Synthesized Nanocrystalline Fe-Al Powders.

The present paper presents a study of the behaviour of FeAl intermetallic powders particles based on 86Fe-14Al, 86Fe-14(Fe5Mg), and 60.8Fe-39.2(Ti37.
