Development Of Cr-Ni Nano Hybrid Coating For Corrosion Resistance And Surface Properties Improvement On Mild Steel

Abstract

Mild steel is one of the engineering alloys that are utilized in many industrial applications (El-Etre, 2007). Its usefulness is traced to its availability, moderate strength and cost effectiveness (Finsgar and Jackson, 2014). However, it is susceptible to corrosion in aggressive environment (Chima, 2021).  The challenges associated with corrosion process in the use of mild steel in industrial processes have led to material deterioration and subsequently materials failure or that of the entire engineering system. Most often, the industrial process is always shut down for proper maintenance at high cost (Singh et al., 2012). Hence, the need to develop means to mitigate or control corrosion process on mild steel becomes imperative. A lot of scientific research approaches have been given to the problem of corrosion on metals (Raja and Sethuraman, 2009; Shyamala and Arulanantham, 2009). Raja and Sethuraman, (2009b) reported that the use of corrosion inhibition coating is the most available cost effective for controlling corrosion. The use of appropriate corrosion inhibitor allows the use of low grade carbon steel, which significantly reduces the capital cost of engineering project when compared to the use of high grade alloys in the same project. (Quraishi, 1999).
