The effects of surfactants on the dynamics and characteristics of plain and composite electroless nickel plating (ENP) are highlighted and discussed herein. An outline of the rudiments of surfactants and some underlying selection criteria is presented at the outset, before emphasis is laid on the salient benefits of introducing such external agents during the plating process. Evidence suggests that their influence on key coating characteristics such as the rate of deposition, structure, corrosion resistance, and the degree of second-phase particle incorporation into the nickel matrix is significant, and depending on the nature and concentration of surfactant employed, can be of immense value to the system.read more

Production and properties of composite electroless Ni-B-SiC coatings
TL;DR: In this article, composite Ni-B coatings enhanced with SiC microparticles on a steel substrate were prepared using the method of electroless plating and structure characterization was performed by means of X-ray diffraction (XRD) analysis and scanning electron microscopy (SEM) in order to draw conclusions concerning the dispersion and incorporation of SiC particles in the NiB matrix and how they affect surface roughness measured by a profilometer.
