Microstructural Aspects of Corrosion

Research output: Contribution to journalArticlepeer-review

Abstract

Abstract: The effect of metal corrosion on the third-order microscopic properties, i.e., the root-mean-square deviation and internal residual stresses of the first-order, was studied. The corrosion process was studied on steel specimens under conditions of superheated steam (250°C) during 500 h. The X-ray diffraction method was taken as the basic research method. The process of corrosion failure was concluded to have two reproducible periods: the period of active metal dissolution and latent passivation period, followed by the corrosion initiation phase. The metal passivity occurs due to the compressive stresses.
