Abstract
A dense and multilayered Si-Cr-Fe-Ti coating was prepared on Nb-Si based alloy by slurry sintering. The oxidation behavior of the coating at 1250, 1350 and 1450 ℃ were systematically investigated. The coating exhibits good oxidation resistance at high temperatures, forming dense and multi-layer scales after oxidation at 1250 ℃∼1350 ℃, while forming a dense glassy silica scale at 1450 ℃. The addition of a certain amount of Ti and Fe is beneficial for the formation and stability of the Cr2TiO5 middle layer, thus effectively inhibiting the further oxidation of Cr2O3 to volatile CrO3.
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.
