Abstract

Phytic acid conversion film was prepared on NdFeB magnets by dipping the NdFeB into phytic acid solution. The morphology, composition, structure and corrosion resistance of the film were systematically investigated. The results showed that the phytic acid film was effective in improving the corrosion resistance of NdFeB magnets. XRD, TEM and FT-IR analyses revealed that the film was amorphous and had a strong peak of phosphate radical (PO ₄ ^3- ). The formation mechanism of the film was also explored by XPS and the potential of zero charge (E _pzc ) measurement at the solution-metal interface.
