Abstract
Corrosion of Ni-based alloy steam generator tubes in simulated primary water leads to the formation of oxides on the surface of the tubes and to the release of corrosion products. The oxides formed on two industrial samples were studied using X-ray photoemission spectroscopy and transmission electron microscopy. The morphology, structure and composition of the oxide layers were determined, and the differences observed were discussed in relation to previous analyses on the as-received inner surfaces. A fine grains layer, alumina on the surface of native oxides could influence the behavior of the surface in primary water.
期刊介绍：
Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies.
This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
