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.
