Evaluation of Corrosive Behavior of Zinc Composite Coating on Mild Steel for Marine Applications

Abstract

Abstract Mild Steel has various forms in which it can be used. It possesses mechanical properties and hence it has found various implementations in many sectors / industries. However, the downside of using mild steel is that it has a high susceptibility to corrosion. There are numerous techniques for protection of mild steel but Zinc electrodeposition techniques is the most preferred method for producing a suitable film coating for the appropriate protection of mild steel. The effect of deposition potential, current, bath composition (including temperature), deposition time and concentration on the structure and crystallinity of the films deposited was systematically studied from various literatures. Introducing zinc into the coating process significantly alters and improves the mechanical and chemical characteristics of mild steel.
