The role of hydrogen on lead-induced localized corrosion of Alloy 690TT
The vital role of hydrogen on lead-induced localized corrosion of Alloy 690TT in the simulated secondary crevice chemistries of pressurized water reactor at 25 °C is investigated by using surface analysis techniques and calculations. Density functional theory (DFT) calculation reveals that there is a coupling effect between lead and hydrogen on inhibiting the kinetic diffusion of oxygen vacancies. Experimental results show that hydrogen causes the change of most easily-corroded location from the grain/carbide interface to the TiN/nucleus interface in the lead-induced corrosion process, which provides a new interpreting sight as for lead-induced stress corrosion cracking mode of nickel-based Alloys.
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.
