TY - CONF A1 - Babutzka, Martin T1 - New findings on the formation of corrosion product layers on zinc in the atmosphere N2 - The presentation shows systematic investigations to describe the corrosion and corrosion product formation processes of pure zinc under the climatic conditions currently prevailing in the Federal Republic of Germany. The investigations in their entirety aim at questioning current and establishing new ways of looking at the formation of corrosion products of pure zinc under atmospheric corrosion conditions. Thus, they make a significant contribution in understanding corrosion protection by zinc and zinc coatings. In particular, the focus is placed on the initial stage of the corrosion product formation. A systematic investigation of this time range, which is characterized by very reactive corrosion products, is only made possible by using gel-type electrolytes. The short periods of time at the beginning of weathering is now measurable and their influence on the formation of corrosion products and the kinetics of layer formation describable. By combining the new electrochemical approach with gravimetric, microscopic and analytical methods, new insights could be gained both on a methodic and scientific level.

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.
