A new approach to the assessment of the corrosion behaviour of zinc coatings under atmospheric conditions can be achieved using gel-type electrolytes as an alternative to standard aqueous test electrolytes. Gel-type electrolytes allow minimally invasive corrosion investigations on zinc coatings. They also provide the possibility to carry out corrosion investigations onsite. By using gel-type electrolytes corrosion-relevant characteristic values such as corrosion currents and polarization resistanc-es can be determined. These allow to describe the formation and the stability of the formed corrosion product layers under various climatic conditions. With this knowledge, a prediction of the zinc coating life cycle is possible. In this contribution, the value of gel-type electrolytes for corrosion research on zinc coatings is presented.
