Electrolytic codeposition technique was adopted in the deposition of Ni-Fe-SiC composite coating on stainless steel substrate, using nickel alloyed with iron as the binder phase with SiC as dispersed particles. The results indicated that the deposit with SiC nanoparticles was level and compact; the crystal-planes of the deposit were (111), (220) and (200). The resistivity of deposit was about 30μΩ•cm. when the Fe(wt.%) ranged from 10% to 50% in the deposit, the electrodeposit Ni-20%Fe-SiC has a strong paramagnetism effect with the smallest coercivity of 2.75×10^-2 A/m. The remanence showed a monotonic decrease with the increasing iron content in deposit. Which proved that the electroformed Ni-Fe-SiC alloy has good electromagnetic property and higher corrosion resistance (with the corrosion rate 0.17 mg/dm² per hour) than those of electroforming Ni-Fe alloy. It is a promising material in the fabrication of micro actuator.
