Abstract
In-situ stress-strain testing under corrosive environment, such as corrosive gasses (e.g. CO2) and highly saline water, is a challenge in testing corrosion fatigue of materials, e.g. for geothermal application or CCS (carbon capture and storage). The first corrosion chamber system was designed for performance at ambient pressure up to 100 °C. The second allows for corrosion fatigue testing at high pressure up to 200 bar and 400 °C. The highly flexible corrosion chambers allow for fast changing and easy alignment of test samples, visual monitoring, CAD-camera monitoring electrochemical measurements, O2-partial pressure or gas partial pressure measurement. Novelty is the fixing of the corrosion chamber directly onto the specimen, that guarantees best fitting and enables the test system to be modified easily suiting a variety of fatigue test machines. All parts of the test system are conforming to the technical rules.
