Abstract
Series of protective layer on high C steel have been successfully developed through transforming various wastes. While high Cr cast steel (HCCS) offers excellent properties of toughness, hardness and corrosion resistance. In this research, the focus on characterisation methods of HCCS were conducted by SEM/EDS, TEM, XRD, Tafel and EIS curves. Results have revealed that modified surface high C steel performed higher corrosion resistance than 16.0–16.5%Cr steel. This finding has opened the new context of using wastes as a source for producing protective layer on the surface of high C steel that integrated profitability of steel products, thus, minimising production cost.
