摘　　要：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MoP—U在 2 2 4%食盐溶液中对碳钢的协同缓蚀作用与机理。结果发现 :5 0 %MoP +5 0 %U(XM— 6 0 6 )在 2 2 4%食盐溶液中对碳钢具有显著的协同缓蚀效应。XM— 6 0 6是一种混合型的缓蚀剂。缓蚀膜主要是沉积膜 ,膜层的主要组分有Zn3 (PO4 ) 2 、Fe PO4 、Fe2 O3 、MoO2 、N[CH2 CH2 OPO(OH) 2 ]3 和 (CH2 ) 6N4 。The synergistic inhibition effect and mechanism of MoP—U for carbon steel in 22.4% brine have been studied by means of weight loss, surface observation, polarization curves, argon ion engraving and XPS. The results reveal that 50% MoP—50%U(XM—606) has remarkable synergistic inhibition effect for carbon steel in 22.4% brine. XM—606 is a mixed inhibitor. The inhibitor film which mainly consists of Zn 3(PO 4) 2,FePO 4,Fe 2O 3,MoO 2,N[CH 2CH 2OPO(OH) 2] 3 and (CH 2) 6N 4 is a precipitation film.
