Název v původním jazyce

Resistance of thermally sprayed coatings in an environment simulating a turbine of geothermal power plant

Popis výsledku v původním jazyce

The paper focuses on the evaluation of the ability of selected heat sprayed coatings to protect the surface of the component in an environment simulating the environment of a geothermal turbine. The subject of testing were coatings based on hardmetals, applied by HVOF technology (WC-CoCr, Cr3C2-NiCr) and Fe and Ni based alloys, applied by HVOF (NiCr, FeCrAlY) and TWAS (FeCrAlNiC, FeCr, NiCr) technologies. It has been shown that although HVOF coatings provide higher protective properties in terms of both corrosion and resistance to mechanical influences, it is also possible to apply the protective coating with TWAS technology if mobile spraying is required. From the materials tested, the Fe-based Metco 8294 can be recommended as a most promising, providing high wear resistance and sufficient corrosion resistance in aggressive environment.
