Effect of surface conditions and alloying elements on the early oxidation behaviour of two austenitic alloys in the pure steam environment

Corrosion behaviour of alumina-forming heat resistant alloy with Ti in high temperature steam

“…On the other hand, those alloys showed internal Al2O3 oxides beneath the Cr2O3 layer when exposed to high temperature air [17,33]. Furthermore, the heat resistant alloys also exhibited internal Al2O3 oxides during steam corrosion in our recent [34] and unpublished studies. The external Cr2O3 was present in all those…”

Microstructure understanding of high Cr-Ni austenitic steel corrosion in high-temperature steam

“…S1b. The co-existence of oxide and metal phases in the inner oxide layer was also observed in 800H alloy after exposure to 650 C high-temperature steam for 250 h [96].…”

Effects of surface treatments and temperature on the oxidation behavior of 308L stainless steel cladding in hydrogenated high-temperature water

“…Perez et al [29] reported that surface finishing could produce a superficial deformation layer in the form of high density of dislocation, which would affect the oxidation behavior. Chen et al [30] investigated the early oxidation behavior of Alloy 800H with the different surface states in 650 °C pure steam. A dual-layer Cr2O3 oxide scale formed on the ground Alloy 800H, the outer layer grown on mechanical polishing and electropolishing specimens was Fe2O3.…”
