Experiment on the Electroforming NiCo-SiC Alloy

Abstract

Abstract. Electrolytic codeposition technique was adopted in the deposition of NiCo-SiC coating on the stainless 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 NiCo-SiC alloy has good electromagnetic property and higher corrosion resistance than those of electroforming Ni-Co alloy. It is a promising material in the fabrication of micro actuator.
