Tóm tắt

The erosion-corrosion mechanism of low-alloy steel in high-ammonia steam generator's chemistry is studied by in situ impedance spectroscopy coupled with an in-depth analysis of formed oxides using glow discharge optical emission spectroscopy. A novel electrode setup that ensures turbulent conditions in the vicinity of the steel sample is used. The effect of temperature (130-230 °C) and flow rate (2-10 dm
