UNTERSUCHUNG VON KORROSIONSINHIBITOREN SÄURIGER BEIZLÖSUNGEN IN DER ANWESENHEIT VON KOMPLEXBILDERN

Corrosion of Soviet and Hungarian carbon steels has been examined in 6% solution of hydrochloric acid. The virtual activation energy and the frequency coefficient have been determined with the help of the Arrhenius equation. The corrosion effect of the Fe(III)-ions, furtheron the inhibitor effect of oxalic acid, sulfosalycilic acid, sodium triphosphate and sodium fluoride have been investigated
