Abstract
Features of multi-component geothermal fluid and physical-chemical processes of its impact on metal of geothermal power plant (GeoPP) equipment were considered. A model of corrosion mechanisms was studied and the results of GeoPP metal corrosionerosion investigation are presented. Experimental data of corrosion-fatigue behavior of TA-5 titanic alloy and 15Cr11MF steel are discussed. Approaches to metal selection were studied, experimental polars and the Verchne-Mutnovsky GeoPP test rig are described.
