Abstract:
Micron zinc sulfate hydroxide hydrate (ZSH) flakes were synthesized by chemical bath deposition with ZnSO4?7H2O and hexamethylenetetramine (HMT), and then embedded into fluorocarbon (FC) coating as fillers. The bond structure, morphology, and elemental composition of micron ZSH flakes were analyzed using Fourier-transform infrared spectrometer, field-emission scanning electron microscope, and X-ray diffractometer. The cross-sectional structure, distribution of ZSH and anticorrosion property of FC–ZSH composite coatings with different mass concentrations of ZSH on pure copper were compared. The results showed that the crystalline ZSH flake was typically hexagonal shape with a smooth and defect-free surface, and could be distributed uniformly in the FC coating, improving its anticorrosion property, especially when the mass fraction of ZSH was 10%.
