Abstract: (28 Views)
In this research, the effect of nickel addition on FeCr/B4C composite hard claddingapplied on plain carbon steel was investigated using inert gas tungsten arc welding. Consumable electrodes were prepared by filling the thin steel sheets with powders of iron, chromium, and B4C with varying weight percentages of nickel from 0 to 9%. The microstructural analysis using anoptical microscope confirmed the presence of Fe2B proeutectic phase blades along with the eutectic phase between the blades. As the weight percentage of nickel increased from 0 to 9%, the corrosion resistance of the coating improved significantly, increasing from 784 Ω.cm2 to 4369 Ω.cm2.Furthermore, as the Ni content of the cladded materials increases, the austenite phase increases and the Fe2B proeutectic phase blades decrease.
