Iron and iron-SiC (NiP-coated) composites with 1, 2, 3 and 5 wt % of SiC, were produced by Direct Metal Laser Sintering (DMLS) p rocess. Sintering parameters namely the laser power, hatch width, hatch spacing and layer thickness were maintained at 180W, 5mm, 0.2mm, 0.05mm respectively while the laser scan speed was varied from 50 to I25mm/s in steps of 25. Salt spray test method was adopted to study the corrosion behaviour of laser-sintered parts. Salt spray tests were conducted in 5.0 % NaCl solution for durations of 24, 48 and 72 hours. Laser scan speed and wt. % of SiC had a significant influence on the density and corrosion behaviour of sintered iron and its composites. At all test durations studied, iron-SiC (NiP-coated) composites have exhibited excellent corrosion resistance when compared with iron.
