采用失重法、表面观察法、极化曲线法、氩离子刻蚀法和 XPS分析法研究 Zn(H2 PO4 ) 2 - N[CH2 CH2 OPO(OH) 2 ]3在海水中对碳钢的协同效应与缓蚀机理。结果发现 :50 % Zn(H2 PO4 ) 2 +50 % N[(CH2 CH2 OPO(OH) 2 ]3(XM- 30 3)在海水中对碳钢具有明显的协同缓蚀效应。 50 % Zn(H2 PO4 ) 2 +50 % N[CH2 CH2 OPO(OH) 2 ]3(XM- 30 3)主要为阴极抑制型缓蚀剂。缓蚀膜主要为沉积膜 ,膜层的主要组分有 Zn3(PO4 ) 2 、Fe PO4 、Fe2 O3和 N[CH2 CH2 OPO(OH) 2 ]3等。
Synergistic effect of Zn (H2 PO4) 2 - N [CH2 CH2 OPO (OH) 2] 3 on carbon steel in seawater by using weight loss method, surface observation method, polarization curve method, argon ion etching method and XPS analysis And corrosion inhibition mechanism. The results showed that 50% Zn (H2 PO4) 2 + 50% N (CH2 CH2 OPO (OH) 2] 3 (XM-30 3) had a synergistic corrosion inhibition effect on carbon steel in seawater. H2 PO4) 2 +50% N [CH2 CH2 OPO (OH) 2] 3 (XM- 30 3) is mainly cathodic suppression type corrosion inhibitor.The corrosion inhibition film is mainly deposited film, the main component of the film is Zn3 ( PO4) 2, FePO4, Fe2O3 and N [CH2 CH2 OPO (OH) 2] 3 and the like.
