- Abstract
In this paper, the Ni–Fe–P ternary alloy coating was fabricated by electroless deposition and the process parameters of coating preparation were investigated in detail via response surface methodology. The optimal bath temperature and pH for Ni–Fe–P ternary alloy coatings were determined by the central composite design with two center points and the statistical model was established to identify the optimal process conditions for Ni–Fe–P ternary alloy coating. The micro-structure of Ni–Fe–P coatings was investigated by scanning electron microscope. The dispersive spectroscopy and X-ray diffraction were used to study the chemical composition of the coatings. The electrochemical impedance spectroscopy and the potential polarization techniques were used to research its corrosion resistance in 3.5 wt.% NaCl solution. The results show that the coating has the optimal corrosion resistance while the bath temperature was 85 °C and bath pH was 8.
