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.

ABSTRACT

Corrosion is a major problem in engineering because of its adverse effects involving the deterioration of materials as well as the destruction of such materials. Corrosion of mild steel causes excessive damage in terms of material loss and reduced efficiency. This imposes attention from researchers worldwide for novel literature review. This study presents a review on the effects that zinc oxide multilayered composite coatings have on the mechanical properties of mild steels. These mechanical properties include hardness, corrosion resistance, wear resistance, impact strength, tensile strength, and flexural strength. It was reported by various researchers that coating with multilayered composite of zinc oxide gave a better result as compared to coating with Zinc alone. From the literature studied, it was noticed that more work is still required to identify and use more natural products as constituents of these multilayered composite.
