Effect of β-SiC Particle Concentration on the Properties of the Duplex Ni-P/Ni-P-β-SiC Coating

Abstract:

Duplex Ni-P/Ni-P-β-SiC coatings were prepared on 2605N double phase stainless steel substrate by electroless plating process. Experiments were carried out to compare and analyze the morphologies, composition and structure of Ni-P/Ni-P-β-SiC by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), XRD and electrochemical workstation, respectively. The results show that duplex Ni-P / Ni-P-β-SiC coating has good associativity between the coating and the substrate, β-SiC particles were uniformly distributed in the coatings, without pores, crack defects and so on. When β-SiC particle concentration is 15g/L, the microhardness reached maximum 623.285HV_0.20, In addition, when the β-SiC concentration is 15g/L, the corrosion reasistence is the best.
