为了改善含石墨粘结涂层的耐蚀性，首先对这种涂层在腐蚀环境中耐蚀性差的原因进行了分析，然后将二正丁基磷酸、ＣｅＦ＿３、Ｓｂ＿２Ｏ＿３和一种Ｃｅ（Ⅲ）配合物Ｃｅ（ＮＯ＿３）（Ｃ＿８Ｈ＿（１８）ＰＯ＿４）＿２分别添加于酚醛环氧－ＭｏＳ＿２－石墨粘结涂层中，考察了它们对这种涂层耐蚀性的影响，并对含Ｃｅ（ＮＯ＿３）（Ｃ＿８Ｈ＿（１８）ＰＯ＿４）＿２的涂层和空白样涂层进行了表面分析。盐雾试验表明，添加Ｃｅ（ＮＯ＿３）（Ｃ＿８Ｈ＿（１８）ＰＯ＿４）＿２可以有效地抑制涂层中ＭｏＳ＿２的氧化和由石墨所引起的金属底材之电化学腐蚀；根据Ｘ射线光电子能谱分析结果可知，添加Ｃｅ（ＮＯ＿３）（Ｃ＿８Ｈ＿（１８）ＰＯ＿４）＿２之所以能够提高含石墨粘结涂层的耐蚀性，应当归因于它在ＭｏＳ＿２晶体表面和金属底材表面的吸附。因此，Ｃｅ（Ⅲ）配合物Ｃｅ（ＮＯ＿３）（Ｃ＿８Ｈ＿（１８）ＰＯ＿４）＿２是含石墨粘结涂层的一种实用性能良好的新型防腐添加剂。
In order to improve the corrosion resistance of graphite bonded coatings, the reason of poor corrosion resistance of this coating in corrosive environment was firstly analyzed. Then, two of n-butyl phosphoric acid, CeF 3, Sb 2 O 3 and a Ce (III) (Ce_ (NO_3) (C_8H_ (18) PO_4) _2) were added to the phenolic epoxy-MoS_2-graphite bonded coatings respectively. Their effects on the corrosion resistance of the coatings were investigated. ) (C_8H_ (18) PO_4) _2 and blank-like coatings. Salt spray tests showed that the addition of Ce (NO_3) (C_8H_ (18) PO_4) _2 can effectively inhibit the oxidation of MoS_2 in the coating and the electrochemical corrosion of the metal substrate caused by graphite. According to the results of X-ray photoelectron spectroscopy It can be seen that the addition of Ce (NO_3) (C_8H_ (18) PO_4) _2 can improve the corrosion resistance of graphite-containing bond coating due to its adsorption on the surface of MoS_2 and the surface of metal substrate. Therefore Ce (Ⅲ) complex Ce (NO_3) (C_8H_ (18) PO_4) _2 is a new anticorrosive additive with good practicability.
