In the course of this master thesis, a new coating for high pearlitic prestressing steels used in wind turbines is tested for its anti-corrosion effect. These prestressing steel wires are used in onshore wind towers. Due to the high tensile forces acting on them and the prevailing environmental conditions, these steel wires are highly susceptible to hydrogen embrittlement. State of the art coatings in the industry are oil, grease or wax based and have major drawbacks in processing and long term durability. For this reason, current prestressing steel wires have a limited service life of up to 20 years. A new paint-based corrosion protection formulation is expected to improve the service life of these steels and minimize the use of resources. In order to be able to make a statement about the improved protective effect of the new corrosion protection formulation, various tests were carried out on both reference specimens with the wax-based protective coating and specimens with the new paint-based protective coating. The static load case generated on the prestressing steels by the prestressing during erection of the wind turbines was tested by constant load tests with continuous in-situ loading in sulfuric acid solution. The dynamic load case induced in the wind turbines by the prevailing wind conditions should be simulated by performing ripple load tests with continuous in-situ hydrogen loading in sulfuric acid solution. The effectiveness of the coating against corrosive media was tested by hydrogen loading. To obtain a trend of hydrogen content over the loading period, samples were loaded with hydrogen for different times. Subsequently, the hydrogen content in the sample was determined via a carrier gas hot extraction. The evaluation of the individual tests showed that the newly developed anti-corrosion coating prevents the formation and absorption of hydrogen to the same extent as the existing wax-based system, with a significantly lower coating thickness.
