Abstract

Purpose – The purpose of this paper is to report the effect of cerium addition on plating rate, microstructure and electrochemical behaviour of electroless nickel‐phosphorus coatings.Design/methodology/approach – The methodology comprised preparation of coatings with different concentration of cerium added in plating bath by electroless, then test coating properties by SEM, XRD and electrochemical workstation.Findings – Coatings prepared with 10 mg/L cerium added in electroless bath have the best corrosion resistance and high deposition rate, smooth and mirror‐like micrograph.Originality/value – The nickel‐phosphorus coating has obtained best corrosion resistance performance (icorr=1.35 μA cm−2) when cerium addition concentration is 10 mg L−1.
