Abstract

The influence of water quality factors such as silica (SiO₂) and chloride ion (Cl^-) on a stability index of water and a corrosion rate of steel was investigated by corrosion weight loss tests and analyses of numerical values. SiO₂ had an ability of corrosion inhibition, and then, tended to change the stability index at chemical equilibrium state. The stability index and corrosion rate were not affected by Cl^- in solution with SiO₂.
