Inhibition of steam-condensate corrosion of copper-based alloys by hydrazine. Final report

Creators

Description

An experimental evaluation was made of the potential inhibiting effect of hydrazine on the corrosion of CDA 687 (aluminium brass), and CDA 706 (90 copper - 10 nickel) in a simulated steam condensate containing ammonia under deaerated and partially aerated conditions. It was found that hydrazine inhibited the corrosion of CDA 687 under deaerated conditions, but increased corrosion rates somewhat under partially aerated (1 ppM oxygen) conditions. Corrosion rates of CDA 706 were more than an order of magnitude lower than CDA 687 and were not measurably influenced by hydrazine
