CORROSION INHIBITION OF Cu 2+ , Fe 3+ FOR Ti IN BOILING ACIDITY SOLUTION
高价铜、铁离子对钛材的缓蚀作用

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.
