Corrosion testing of materials in simulated superheated geothermal environment

Thorhallsson, Andri Isak; Stefansson, Andri; Kovalov, Danyil; Karlsdóttir, Sigrún (Elsevier BV, 2020-05)

This paper reports the results of corrosion study for carbon steel, austenitic stainless steel, as well as titanium and nickel-based alloys which were tested in a simulated superheated geothermal environment (SSGE) in flow-through reactors to investigate ...
Phase Evolution and Microstructure Analysis of CoCrFeNiMo High-Entropy Alloy for Electro-Spark-Deposited Coatings for Geothermal Environment

Karlsdóttir, Sigrún; Geambazu, Laura E.; Csaki, Ioana; Þórhallsson, Andri I.; Stefanoiu, Radu; Magnus, Fridrik; Cotrut, Cosmin (MDPI AG, 2019-06-21)

In this work, a CoCrFeNiMo high-entropy alloy (HEA) material was prepared by the vacuum arc melting (VAM) method and used for electro-spark deposition (ESD). The purpose of this study was to investigate the phase evolution and microstructure of the ...
