Abstract

This study explores the possibility to extend the service temperature of austenitic steel 316Ti in liquid lead to 700 °C. To improve the material compatibility, 316Ti is subjected to three different pre-treatments prior to Pb exposure: pre-oxidation in hot air, aluminizing by pack cementation, and the combination of both. In exposure tests with duration up to 5000 hours, the combined pre-treatment comprising aluminizing by pack cementation and subsequent pre-oxidation is found to provide the most effective corrosion protection to austenitic steel 316Ti in contact with liquid Pb containing 2 × 10⁻⁷ wt% dissolved oxygen at both 600 and 700 °C.

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.
