This paper reviews the principles of cathodic corrosion protection and the different ways zinc anodes are applied to reinforced concrete through wire arc spraying. It also explains how the lifetime of zinc coatings can be extended with an organic topcoat and presents related test data. Paper includes a German-language abstract.

The growing use of thermal spray technology in manufacturing is increasing the need for knowledge regarding the behavior of thermal spray coatings in aggressive environments. Due to the different characteristics of the spraying processes and materials used, the mechanisms of attack can vary greatly from layer to layer depending on the application. This paper presents a detailed investigation of corrosion mechanisms at room temperature and their effect on a wide range of thermally sprayed metals and ceramic-metal (cermet) composites. Paper includes a German-language abstract.
