- Аннотация: The corrosion of 08PS mild steel in 2 M HCl in the presence of cationic (alkylbenzyldimethylammonium chloride (Catamin AB)), amphoteric (cocamidopropyl betaine (CAPB)), anionic (sodium lauroyl sarcosinate (SLS), sodium oleoyl sarcosinate (SOS), sodium dodecylbenzenesulfonate (SDBS)), and non-ionic surfactants (indirect material ОР-10) was studied. The protective effects of the surfactants on steel corrosion decrease in the series: Catamin AB > CAPB > SOS > OP-10 > SLS > SDBS. The possibility of creating mixed corrosion inhibitors (CIs) based on the studied surfactants and urotropine, a known corrosion inhibitor of steel, is considered. It is shown that the Catamin AB + urotropine and CAPB + urotropine mixtures are the most promising formulations for the creation of efficient CIs of steel. These mixtures of CIs are recommended for application in HCl solutions with temperatures up to 60 and 80°C, respectively. The total content of the mixed CIs in the corrosive medium should be 5 mM. The molar ratio of a surfactant and urotropine in the mixed CIs is 1:9.
