Materials Science Aims and scope

Abstract

We have studied the effect of Naftokhim-3, Naftogaz-1, Kaspii-2, Tyumen-2, and Travis TKh-1102 inhibitors on the corrosion-mechanical strength of pipe steel in hydrocarbon and aqueous media containing hydrogen sulfide. We have established that these inhibitors increase the plasticity and fracture energy of steel and, at the same time, worsen its strength properties. In addition, they decrease the crack growth rate under cyclic loading. Naftokhim-3 and Naftogaz-1 inhibitors have the highest efficiency in aqueous hydrogen-sulfide media and Naftokhim-3 in hydrocarbon media.
