- W2165340547 abstract "In the present article, the corrosion of the nickel-base alloy 625 (NiCr22Mo9Nb; 2.4856) in strongly oxidizing hydrothermal aqueous solutions of hydrofluoric acid (HF), hydrobromic acid (HBr), or hydriodic acid (HI), respectively, is investigated. The reaction conditions were temperatures between 25 and 500°C, pressure of 24 MPa, acid concentrations of 0.05 mol/kg, oxygen concentrations of 0.5 mol/kg, and reaction times of 50 h (for HF and HBr), or 3.5 h (for HI), respectively.The investigated alloy 625 tubular samples were corroded by a continously flowing solution. The corrosion of alloy 625 caused by HF is only weak corrosion over the entire temperature range. HBr causes pitting at T > 170°C. At temperatures between 320 and 380°C, general corrosion due to transpassive dissolution leads to severe material loss. In supercritical solutions of low densities, corrosion is negligible. HI was oxidized almost completely to iodine leading to a plugging of the reactors after short times.Samples of ceria stabilized tetragonal zirconia polycrystal (Ce-TZP) were corroded inside the tubes in a section where T = 500°C. The only corrosion phenomenon which was observed in all acids was intergranular corrosion, with HF being less corrosive than HBr. Neither a weight loss nor a tetragonal to monoclinic phase transformation could be measured.Furthermore, the corrosion behaviour of both materials was compared to that caused by other acids." @default.
