利用电化学阻抗谱研究了方解石及三聚磷酸铝环氧涂层的耐蚀性能,并提出了它们的作用机理.结果表明，方解石只起体质颜料作用，不具备缓蚀性能；而三聚磷酸铝因在钢基表面作用形成致密的保护膜则表现出优良的缓蚀性能.
利用電化學阻抗譜研究瞭方解石及三聚燐痠鋁環氧塗層的耐蝕性能,併提齣瞭它們的作用機理.結果錶明，方解石隻起體質顏料作用，不具備緩蝕性能；而三聚燐痠鋁因在鋼基錶麵作用形成緻密的保護膜則錶現齣優良的緩蝕性能.

The epoxy coatings on A3 steel sheets containing calcite or aluminum triphosphate (AlTP), were investigated by Electrochemical Impedance Spectroscopy (EIS). The results showed that calcite pigment is not an inhibitor, but an extender pigment, and that AlTP pigment can considerably enhance the protective performance of epoxy coating. The triphosphate ion at the interface between the steel substrate and the coating can complex with the corrosion-product, such as ferric and ferrous ions, and form a compact protective film which effectively separates the steel substrate from the aggressive media.
