The influence of ascorbic acid concentration on the potential vs time dependence was investigated. The inhibition effect of ascorbic acid in concentration range 0.1 – 1.5 g/l was also examined using weight loss and electrochemical methods. The optimal concentration of ascorbic acid for protection of the low-alloy 17H1S steel in the NS4 solution against corrosion was defined. © 2022 The Authors. Published by ELSEVIER B.V.

Introduction The economic losses from the corrosion of metals are huge and estimated as 2…4% of gross national product in the developed countries. The losses of metal, including the mass of failed metal structures, products, equipment, range from 10 to 20% of annual steel production. 2 u h ub i h y E E V. h s is n pen ce t l e B N - 1st Virtual International Conference “In service Damage of Materials: Diagnostics and Prediction” Evaluation of the green inhibitor effect on the corrosion of pipeline steel in NS4 medium Tetyana Kalyn a , Liubomyr Poberezhny a *, Pavlo Popovych b , Yurii Rudiak c , Oleg Korol d , Liubov Poberezhna a a Ivano-Frankivsk National Technical University ofOil and Gas, 15 Karpatska St., Ivano-Frankivsk 76019, Ukraine b West Ukrainian National University, 11 Lvivska St. Ternopil 46009, Ukraine c Ternopil National Medical University, 1 Maidan Voli, Ternopil 46001, Ukraine d Ternopil Ivan Puluj National Technical University, 56 Ruska St., Ternopil 46001, Ukraine
