Abstract

Researches in the area of zinc coatings on steel are rather unending because of the unique properties and the very low cost that it offers. In this study, an attempt to develop a compact and structurally modified coating that will work against chemical and mechanical deterioration with the help of Zn–Tic/Tib was studied. Scanning electron microscope and atomic force microscope were used to study the surface morphology, the topography, and the surface adherence properties of the coatings. Micro-hardness of the deposited substrate, the electrochemical behavior and the corrosion properties of the deposits were investigated by means of high impact diamond Dura scan micro-hardness tester and gravimetric method. From the results, the deposition of Zn–Tic/Tib composite particles showed good protection against corrosion and also improved the hardness values. Hence, Zn–Tic/Tib alloy coating on mild steel can be used to improve the properties of mild steel.
