51318-10676-Research on the Effects of Environmental Parameters on AC Corrosion Behavior

AC corrosion experiments were done on two kinds of typical soil simulants with different contents of (Ca2+), (Mg2+) and (Na+) to study the effects of environmental and cathodic protection parameters on AC corrosion rates.

AC corrosion experiments were carried out in two kinds of typical soil simulated environments with different contents of calcium ion (Ca2+), magnesium ion (Mg2+) and sodium ion (Na+) to study the effects of environmental and cathodic protection parameters on AC corrosion rates. Based on the weight loss experiments results and corrosion morphology analyses in two different environments, as well as under different CP polarized potentials and AC current densities, the difference of AC corrosion behavior in different environments and CP levels were analyzed. Besides, the effective CP polarized potentials under different AC current densities in two environments were explored.

 Key words: AC corrosion, environmental parameters, cathodic protection, corrosion behavior, installed coating costs.
