摘要
用静态失重法、稳态极化曲线和扫描电镜初步研究了ＤＡＭＥＰＮａ＿２－及ＤＡＭＥＰＮａ＿２－庚烷－戊醇－自来水微乳液对２０￣＃碳钢的缓蚀性能，结果表明（１）两者都为抑制阳极为主的混合型缓蚀剂，（２）该微乳液具有较好的缓蚀性能，缓蚀率可达９９％以上，而单一ＤＡＭＥＰＮａ＿２－的缓蚀率仅为１６．２％。
篢he corrcosion inhibition of microemulsion con posed of DAM EPNa_2- heptane -pentanol-tapwater was studied by the weight-loss methed， polarization curves and electron-microscope. The re-sults showed that（1） DAMEPANa_2 in the microemulsions had an excellent inhibition effect． The effi-ciency of corrosion inhibition was above 99％，but it was only 16．2％in the non-microemulstion sys-tem.（2） DAMEPNa_2 acted as an anodic inhibitor in the tap water or in it’s microemulsions.
