Abstract
Pt-rich γ-γ’ bond-coatings for thermal barrier coating systems may lead to detrimental pore formation. An extensive analysis of literature on voids nucleation and growth in the different metallic components of several kinds of TBC systems was performed. The study then focused on Pt-rich γ-γ’ bond-coating/Ni-based superalloy systems employing an original statistical analysis of voids formation and spatial distribution through secondary electron microscopy with focused ion beam sequential cross sectioning and synchrotron X-Ray tomography. It was found that pores at the Pt-rich γ-γ’ bond-coating/superalloy interface form due to the Kirkendall effect, with the highest concentration located at the Pt diffusion front.
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.
