Research Progress of Corrosion Induced by Second-Phase Particles in Microalloyed High-Strength Rebars—Review

Abstract

The research progress surrounding second-phase particle-induced corrosion has been expounded through extensive work, including local corrosion (pitting corrosion, crevice corrosion, stress corrosion) of Al2O3, (RE)-AlO3, CaS, MnS, NbC, and other particles in microalloyed high-strength rebars. By summarizing the local corrosion mechanism of these particle-induced rebars, this review further explores the fact that these particles play an inducing role in the local corrosion of microalloyed high-strength rebars, which has guiding significance for research on the induced corrosion of microalloyed high-strength rebars.
