【摘要】 采用交流阻抗法和动电位扫描法研究了不同浓度的钛钨杂多酸钾在1%Na2SO4溶液中对X70钢的缓蚀作用.结果表明,钛钨杂多酸钾属于以抑制阴极过程为主的混合型缓蚀剂,在所研究的浓度范围内,随其浓度的增大,缓蚀率先增大后减小,最佳浓度值为0.3g/L.更多还原

【Abstract】 The inhibition effect of K13[Ce(TiW11O39)2] on the forrosion of X70 steel in 1% Na2SO4 solution was studied by means of electrochemical impendence spectroscopy and potenfiodynamic polarization curves.It was found that K13[Ce(TiW11O39)2] was a mixed inhibitor,which mainly restrained cathodic process,within the range of concentration studied,the inhibitive effect firstly increased gradually with the increasing of its concentration and then decreased.The optimal concentration was 0.3 g/L.更多还原
