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,argonion 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 Zn3(PO4)2、FePO4Fe2O3、MoO2、N[CH2CH2OPO(OH)2]3 and (CH2)6N4 is a precipitation film.
