    <title language="eng">Corrosion resistance of high-alloyed and alternative materials in an artificial geothermal water</title>
    <abstract language="eng">Many technologies have been developed to take advantage of geothermal energy, which became  a feasible energy source to replace fossil fuel supply. Nevertheless, service conditions in geothermal facilities are due to the chemical  composition of hydrothermal fluids and involved high temperatures, in many cases, extreme in terms of corrosion. Therefore, materials selection based on preliminary material qualification is essential to guarantee a secure and reliable operation of the facilities.&#13;
This contribution deals with the evaluation of the corrosion behavior of two high-alloyed metallic materials and α-Al2O3 in an artificial geothermal fluid simulating the conditions in the Northern German Basin, a location with high geothermal potential. The suitability of the super austenitic stainless steel UNS N08031 and the nickel base alloy UNS N06059 in this geothermal fluid obtained by electrochemical measurements and exposure tests is addressed. As an alternative to the suitable but costly UNS N06059 that showed excellent corrosion resistance against pitting corrosion, ceramic made of α-Al2O3 represents an interesting possibility for selected components to be used in the construction of geothermal facilities</abstract>

    <title language="eng">Suitability of high-alloyed or alternative non-metallic materials in high saline artificial geothermal waters</title>
    <abstract language="eng">Many technologies have been developed to take advantage of geothermal energy, which became a feasible energy source to replace fossil fliel supply. Nevertheless, Service conditions in geothermal facilities are due to the Chemical composition of hydrothermal fluids and involved high temperatures, in many cases, extreme in terms of corrosion.

This contribution deals with the evaluation of the corrosion behavior of two high-alloyed metallic materials and a-A1203 in an artificial geothermal fluid simulating the conditions in the Northern German Basin, a location with high geothermal potential. The suitability of the super austenitic stainless Steel, alloy 31, and the nickel base alloy 59 in this geothermal fluid obtained by electrochemical measurements and exposure tests is addressed. As an alternative to the suitable but costly alloy 59 that showed excelient corrosion resistance against pitting corrosion, ceramic made of a-A1203 represents an interesting possibility for selected components to be used in the construction of geothermal facilities.</abstract>
