Influence of fuel combustion on the corrosion behavior of pipeline steels in fire flooding technology

Abstract

To study the oxidation behavior of a commonly used pipeline materials of 37Mn5 steel in the process of fire flooding technology, a simulation device of organic fuel combustion was designed and used for comparative study between air and kerosene atmosphere. The products generated after kerosene combustion greatly affected the growth of iron oxides at 600 and 700 °C. In air, the oxide scale shows a defective morphology with bulge and spallation. While in the kerosene atmosphere, carbon particles after incomplete combustion can exist on the surface and inside the oxide scale, which would inhibit the reduction of oxides by carbon in substrate and the decarburization of 37Mn5 steel.

The Oxidation Properties of a NiCrAlY Coating Fabricated by Arc Ion Plating

“…But NiAl2O4 and Ta2O5 exhibit poor performance. The coefficients of thermal expansion for the three oxides are different, especially between α-Al2O3 and Ta2O5 [19,20]. This resulted in the formation of pores and cracks.…”

“…Therefore, the presence of the NiCrAlY coating improves the oxidation resistance of the N5 superalloy. [19,20]. This resulted in the formation of pores and cracks.…”

Al2O3-modified 7YSZ thermal barrier coatings for protection against volcanic ash corrosion

“…Additionally, doping of more resistant stabilizers (e.g., Al and Ti) in ceramic coatings is also a feasible approach 18 . To prevent CMAS infiltration into the porous 7YSZ coating, laser glazing and remelting of the 7YSZ coating to provide a dense layer are typical methods 19,20 . The aim of the above traditional approaches in the published literature is to hinder the chemical reaction and infiltration of molten CMAS.…”

Corrosion Behavior of SiO2-Al2O3 Glass Composite Coating on TC4 in Marine Environment

“…Surface coatings are preferred choice to enhance the corrosion resistance of titanium alloys, such as metallic coating [11][12][13][14] and polyester composite coating [15][16][17][18][19][20]. TiN and TiN/Ti multilayer coatings were found to be a good corrosion-resistant metallic coating and can improve the corrosion resistance of Ti-based alloy significantly [21][22][23][24].…”
