The isothermal corrosion behaviour obtained by mass gain of the steels in the gas phase, the liquid phase and the intermediate phase gives surface corrosion rates around 0.1 to 0.8 mm/year at ambient pressure and much lower about 0.02 to 0.2 mm/year at 100 bar where the CO 2 is in its supercritical state. Severe pit corrosion with pit heights around 4.5 mm are only located on the 42CrMo4 steel.

With mounting 2 independent full 2-grade titanium autoclave systems (running up to 250 bar and 300 °C) pressures up to p=100 bar are possible. In 2010 a specific corrosion chamber of 2-grade titanium working up to 100 °C, flowing aqui fer water with different gas mixtures was designed to fit to a high cycle fatigue testing machine. Long term fatigue experiments simulating fatigue crack growth under corrosive environments will soon start. These experiments may not only help engineering a CCS site, but results can be used to improve the maintenance of geothermal energy production sites, especially moved parts such as pumps and shafts.

This highly corrosive environment arises when the flue gasses, mainly composed of CO2 , are injected into saline aquifer water. Immediately carbonic acid is formed causing corrosive attack of the injection steels. The influence of heat treatment on the local corrosion resistance was demonstrated in laboratory experiments at 60 °C and ambient pressure for three steels X46Cr13 (1.4034), X20Cr13 (1.4021) and X5CrNiCuNb16-4 (1.4543) under a similar liquid corrosive environment as found at a geological onshore CCS-site in the Northern German Bassin.

In particular, several orientations and frequencies have been investigated, thus allowing the assessment of the influence of these parameters on the crack growth rate. In addition, oxidation experiments have been carried out to characterize the kinetics of the outer oxide scale growth at the same temperature. On the other side, crack growth has been simulated with the Finite Element program ABAQUS in real test conditions by the node release technique. The nodes are released according to the measured crack growth rate. The simulation results are compared with the test results on the basis of the computed Crack Tip Opening Displacement (CTOD). For this purpose, the crack is propagated until a stabilized value of the CTOD is obtained. This is usually the case when the crack has crossed the initial plastic zone. The procedure provides an evaluation of the effects of cycle frequency, crystal orientation, plasticity and oxide induced crack closure.

Nickel-base superalloys are especially designed to resist high temperature oxidation by process gases. To determine this high temperature behaviour oxidation testing was carried out using samples cut perpendicular to (001)-direction. Microstructures were characterized by X-ray diffraction XRD, Light Microscopy LM, Scanning Electron Microscopy SEM, and X-ray energy dispersive spectroscopy (EDS), after a series of heat treatments (950 °C, 0 h - 1000 h). Mass gain and the respective thicknesses of the different oxide layers were measured to determine oxidation kinetics. In general, the isothermal oxidation behaviour at 950 °C, as defined by weight gain, follows a parabolic law with a parabolic rate constant around 1.4 · 10-2 mg2/(cm4 · h). A short incubation time is followed by the constitution of a multi-layered oxide scale. The oxide scale consists of a three layer structure. An outer scale contains a Ti-bearing thin film associated as TiO2 and NiTiO3 but mostly Cr attributed to Cr2O3, (Ni/Co)Cr2O4 beside NiTaO4. This outer scale is connected to a discontinuous layer of inner oxidation consisting mainly of Al2O3, which is followed by an area of γ´-depletion within the base material.

Microstructures were characterized by X-ray diffraction, light microscopy, scanning electron microscopy, and energy dispersive X-ray, after a series of heat treatments (700 h to 2 years).

In laboratory experiments different heat treated steels used as injection pipe with 13% Chromium and 0.46% Carbon (X46Cr13, 1.4034) as well as 0.2% Carbon (X20Cr13, 1.4021) were tested. Also X5CrNiCuNb16-4 (1.4542) was investigated as typical steel used for geothermal pumps. Keeping stable environmental conditions in laboratory experiments the samples were exposed to the distinct synthetic aquifer environment saturated with technical CO2 at a flow rate of 3 l/h for up to 6 months. Independent of the exposure time the least amount of pits is found on hardened steels with martensitic microstructure where X5CrNiCuNb16-4 shows fewer pits than X46Cr13 and X20Cr13. Regarding steels with similar Cr-content the higher Ccontent in 1.4034 results in fewer pits compared to 1.4021.
