Influence of Water Quality Factors on Stability Index of Water and Corrosion Rate of Steel

摘要

The influence of water quality factors such as silica (SiO_2) 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. SiO_2 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 SiO_2.
