Pulse electrodeposited Ni–C films and its performance

Abstract

In this study, Ni–C films have been fabricated via pulse electrochemical deposition and carbon sol reinforcement methods. The surfacing of prepared films significantly improved due to the uniform distribution of nanoparticles. Additionally, the maximum thickness is attained when the concentration of carbon sol is 15[Formula: see text]ml/L. X-ray diffraction analysis of the Ni–C composite films reveals adding carbon sol effectively refines the grain size of prepared films. The highest film hardness, 420[Formula: see text]HV, is achieved at a carbon sol concentration of 15[Formula: see text]ml/L, corresponding to the best wear and corrosion resistance. Excessive carbon sol can lead to agglomeration of carbon particles, resulting in defects such as cracks and pores within the coating, thereby degrading its performance.
