Formation of protective layers by 5-chlorobenzotriazole and its mixture with sodium fluphenaminate on low-carbon steel from aqueous solutions

It is shown that introduction of R = Cl substituent into benzotriazole (BTA) structure imparts elevated acidity and hydrophobicity to the molecule and improves the compound’s protective and adsorption properties for low-carbon steel in aqueous solution. The surface layer composition of 5-chloro-BTA...

Description
Summary:It is shown that introduction of R = Cl substituent into benzotriazole (BTA) structure imparts elevated acidity and hydrophobicity to the molecule and improves the compound’s protective and adsorption properties for low-carbon steel in aqueous solution. The surface layer composition of 5-chloro-BTA and a blend thereof with sodium fluphenaminate is revealed by XPES. It is shown that the inhibitors under investigation are located in a position close to vertical on the surface of oxidized St3. The layer thicknesses of the inhibitors under investigation are determined and compared by XPES and ellipsometry.
