Abstract

Electroless nickel (EN) coatings have gained widespread acceptance as it provides uniform deposit on irregular surfaces, direct deposition on surface activated non – conductors, high hardness and excellent resistance to wear, abrasion and corrosion. The effect of surfactants on the surface roughness of electroless Nickel – Phosphorus surface protective coating obtained from an alkaline bath is presented in this paper. In this study the influence of surfactants sodium dodecylsulfate (SDS) and cetyl trimethyl ammonium bromide (CTAB) on the surface roughness of coated samples were investigated. It was observed that the surface roughness, surface hardness and surface morphology of Ni-P coating were clearly influenced by the addition of surfactants SDS and CTAB. The complete experimental details, results obtained and their analysis are presented in this paper.
