Abstract
The article presents the results of experimental studying of corrosion resistance of corundum, titanium nitride and TiB2/TiNi powder samples in supercritical aqueous fluid (SAF). The tests were proceeded in autoclave (temperature of 400 °C, steam pressure of 100 MPa) during 100 hours. As a result, it was found that Al2O3 (corundum) and TiN are resistant materials, whereas the TiB2 phase of eutectic alloy dissolves in an aqueous SAF medium. Deep corrosion index value is considered.
