We study the influence of the partial pressure of hydrogen sulfide (1–5 atm) and temperature (25–120°C) on the corrosion behavior of 09G2S steel in model seawater and the degree of its hydrogenation. It is shown that the increase in the partial

Electrochemical behavior of 15Kh2NMFA steel in borate-buffered reactor water at temperatures of 22–300°C under equilibrium pressures

Autor: I. M. Antoshchak, V. I. Vorobel, E. I. Lychkovs’ky, V. I. Pokhmurs’kyi

Publikováno v: Strength of Materials. 42:64-69

We study the corrosion-electrochemical behavior of 15Kh2NMFA steel in borate-buffered reactor water within the temperature range 22-300°C and establish the relationship between the temperature dependences of the corrosion-fatigue crack growth rates

We describe some results of our electrochemical investigations of a model of the “renewed surface–passivated surface” galvanic couple for 15Kh2NMFA steel in borate-buffered reactor water with pH8 under the action of high temperatures (up to 300

Effects of metallurgical and electrochemical factors on the cracking of some nuclear power station steels at high temperatures

Autor: I. M. Antoshchak, I. P. Gnip

Publikováno v: Strength of Materials. 28:210-216

Up to now, inadequate attention has been paid to the mechanism whereby metallurgical inhomogeneities in steels and electrochemical factors affect static corrosion and cyclic corrosion cracking under the conditions encountered in hot aqueous media. In

Investigation of the Serviceability of Tubing Strings Made of Steel of Strength Group K

Autor: O. I. Radkevych, I. M. Antoshchak, A. V. Vasylyk, R. M. Yurkevych, H. V. Chumalo

Publikováno v: Scopus-Elsevier

The resistance of steel of strength group K to corrosion, hydrogen-corrosion, and stress-corrosion fracture is analyzed for hydrogen-sulfide-containing media of the Lokachi gas field and in the NACE solution. It is shown that the indicated type of st
