Electrodeposition and enhanced corrosion resistance of Zn-Ni alloy coatings with organic additives on low-carbon steel

Key Points

The addition of organic additives significantly improves the corrosion resistance of Zn-Ni alloy coatings on low-carbon steel.
Additives were found to enhance microhardness, surface morphology, and overall coating performance compared to coatings without additives.
Structural analyses confirmed increased nickel content in the coatings, correlating with improved electrochemical properties.
These findings suggest that additive-assisted Zn-Ni coatings can effectively prolong the lifespan of steel components in aggressive environments.

Abstract

Corrosion remains a critical challenge for numerous industrial sectors, leading to substantial economic losses worldwide. This study investigates the electrodeposition of Zn-Ni alloy coatings on low-carbon steel using sulfate-based baths, with and without the incorporation of organic additives such as saccharin and 2-butyne-1,4-diol. The influence of these additives on coating properties was thoroughly examined. Results revealed notable enhancements in microhardness, surface morphology, and corrosion resistance when additives were present. Structural and compositional analyses (EDS, XRD) confirmed an increased nickel content, which correlated with improved electrochemical performance. Overall, the additive-assisted Zn-Ni coatings exhibited superior protective behavior, highlighting their potential for prolonging the lifespan of metallic components in aggressive environments.
