【摘要】 研究了高价铜、铁离子对沸腾的酸性介质中钛管的缓蚀保护作用．结果表明，在４０％Ａｌ２（ＳＯ４）３溶液中，当铜离子浓度达到０．０１％（ｗｔ）时，可使钛的腐蚀率降到０．１ｍｍ／ａ以下，在ｐＨ＝１的沸腾稀硫酸溶液中，当铜离子浓度达０．０３％或铁离子浓度达０．０１％时，可使钛管的腐蚀率降到０．０２ｍｍ／ａ以下．更多还原

【Abstract】 The corrosion inhibition action of Cu 2+ Fe 3+ for Ti tube in boiling Al 2(SO 4) 3 solution and dilute sulphuric acid solution has been investigated.The experiment results indicated that when the concentration of Cu 2+ and Fe 3+ was 0.01%(wt),respectivly, the corrosion rate of Ti tube were suppressed to <0.1 mm/a in Al 2(SO 4) 3 solution. When the concentration of Cu 2+ was 0.03% or that of Fe 3+ was 0.01%, the corrosion rate of Ti tube were suppressed to < 0.02 mm/a in dilute sulphuric acid.更多还原
