Abstract
In this paper, anticorrosion film was prepared on the surface of AZ31B magnesium alloy by SNAP (self-assembled nanophase particle) technology. Nanoparticle morphology, sol conductivity, surface morphology and corrosion protection of SNAP film were studied by transmission electron microscopy (TEM), scanning electron microscopy (SEM), electrochemical impedance spectroscopy (EIS) and conductivity, respectively. And we obtained content effect of precursors of 3-glycidoxypropyltrimethoxysilane (GPTMS) and tetraethoxysilane (TEOS), solvent of water, cosolvent of ethanol and crosslink agent of triethylene tetramine (TETA) on the corrosion protection of the SNAP film. The results indicated that, the corrosion protection of the SNAP film were improved when the content of TEOS, TETA and water increase, however it decreased when the contents of TEOS and TETA increased further; The effect on the corrosion protection of the SNAP film could be neglected when the ethanol content was small.
