Though Ni-based superalloys show a high oxidation and corrosion resistance, coatings can still improve these properties, especially if used at temperatures up to 1000 °C. Here, a coating was prepared by applying a boehmite-sol via dip-coating and a

Technically relevant P92 steel (9% Cr) was coated with a micron-thick porous alumina layer prepared by sol-gel technique and treated with flue gas (60 CO2-30 H2O-2 O2-1 SO2-7 N2 (mole fraction in %)) at 650 °C to mimic an oxyfuel-combustion process.

Samples of sol–gel alumina-coated and uncoated P92 steel were exposed to flue gas at 650 °C for 300 h to register and characterize the early stages of the protection effect of that coating. As a result of this treatment, a 50-µm-thick bilayered o

Porous alumina films with thicknesses of a few microns were prepared via a dip-coating technique on steel P92. The coating is shown to protect the steel against massive corrosion, which is typical in the hot reactive environment of coal-fired power p
