Xiaochao Shen, Jiali Wang, Gang Xin
Abstract
Na (SDS), the zeta potential of PVDF particles was -30.6 mV. The densification and uniformity of the composite layers with a higher amount of PVDF particles were achieved, which resulted in the superior resistance to fluoride ion corrosion. After heating at 180 °C, the PVDF particles were melted, spread, and filled into the pores of the composite layers, which led to the further enhanced corrosion resistance. It was demonstrated that the zeta potential of PVDF particles affected the dispersion, stability, and codeposition with electroless nickel, which resulted in the uniform and dense composite layers and enhanced the corrosion resistance of the fluoride ion.
