Water Soluble Corrosion Inhibitors to Protect Immersed Steel and Aluminum

摘要

The water in tanks used for ultrasonic tests needs a corrosion inhibitor to protect immersed steel and aluminum metal parts. Very dilute concentrations of sodium nitrite and silicon dioxide (the active ingredient of sodium silicate) separately provide complete corrosion protection for at least three days.
