Abstract
Electrochemical investigations were carried out on rebars of black steel and stainless steel with and without weldings. The effect of mixed-in chloride as well as ingress of chloride was investigated. The critical chloride concentration of rebars embedded in mortar with mixed-in chloride was more than ten times higher for stainless than for black steel. Welding, however, reduced the critical chloride concentration to 1/3-2/3 of that of the unwelded stainless steels, iron deposits or swarf from production tools acted as a starting point for corrosion attack. Measurements of oxygen reduction indicated that the cathodic reaction is inhibited on stainless steel, and this might limit the corrosion rate after initiation. (A)
