Abstract 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 the corrosion behaviour to aid in the future material selection for high temperature deep geothermal application. The testing fluid was superheated steam (T = 350 °C and P = 10 bars gauge) containing H2S, CO2 and HCl with condensate of pH = 3. The corrosion rate for all samples was negligible but carbon steel was prone to localized damage under a magnetite film with a sulphur rich sublayer.

模拟过热地热环境中的材料腐蚀试验

摘要 本文报告了碳钢、奥氏体不锈钢以及钛和镍基合金的腐蚀研究结果，这些合金在流通式反应器的模拟过热地热环境 (SSGE) 中进行了测试，以研究腐蚀行为，以帮助在未来高温深部地热应用的材料选择中。测试流体是过热蒸汽（T = 350 °C 和 P = 10 巴表压），其中含有 H2S、CO2 和 HCl 以及 pH = 3 的冷凝物。所有样品的腐蚀速率可以忽略不计，但碳钢在具有富硫亚层的磁铁矿膜。
