The desire to increase the corrosion resistance of mild steel for engineering purposes prompted this experiment. The carburizers were chosen from animal bones, periwinkle shell, and snail shell. Each of these carburizers was pulverised and mixed with calcium carbonate, an energizer (CaCO3). At temperatures ranging from 700 to 1000°C, the treatment was carried out at 100°C intervals. 3.5 percent sodium chloride was used to simulate a marine environment. Linear polarisation was used for the corrosion experiment, and an optical microscope was used to assess the impact of the treatments on the structures. According to the findings, the selected carburizers can compete favourably and perform better in the simulated maritime environment than the as-received (AR) sample. This occurs as a result of carbon atom diffusion from the carburizer through the steel sample's epidermis. Finally, it was revealed that the carburized samples outperformed the AR samples in terms of corrosion resistance.
