Paper Title:
Electrospark Deposition of Fe-Based Alloy Coating
  Abstract

Electrospark deposition (ESD) is a promising process to produce hard and wear-resisting coating on metallic substrates. Fe–Cr–Ni–Si–Mo–W–B–Co–Al alloy rods were used as electrode to produce coatings onto a high carbon cast steel roll substrate. Different parameters were used and the coatings have an average thickness of~80 μm, which are metallurgically bonded to the substrate. The microstructures of the coating prevail in nanosized grains and amorphous structures. The primary phases of the coating contain C0.055Fe1.945,(Fe,Cr)7C3,Fe7Mo3 and Al0.99Fe0.99Ni0.99. The maximum microhardness value of the coating is about 1837.4 HV. The study reveals that Fe-based ESD coating has a better quality and has a high hardness on the cast steel roll.
