Structural damage caused by corrosion in concrete structures is widespread and requires extensive repair work. The installation of corrosion protection systems for constructions that are under unfavorable conditions is urgently necessary. Thermally sprayed coatings serving as anode have been developed from the cathodic protection of steel. These systems have attracted attention because of their performance and lower cost advantages, and they are about to enter the competitive anode system market. Thermally sprayed zinc coatings are applied to the surfaces of steel-reinforced concrete components that are affected by corrosion. In this article, the ability of the system to deliver a protective current is verified by field tests in a marine structure in the Arabian Gulf that was discussed in 1997. Paper includes a German-language abstract.
