Design of long-term ablation protective Zr0.92Ta0.04Si0.04O2 coating via large lattice distortion and limited phase precipitation
Thermally sprayed Zr-Ta-Si-O coatings were investigated to overcome the oxygen blocking limitations of traditionally self-derived porous ZrO2 layer. The individual solid solution of Ta and Si into ZrO2 lattice was respectively found trapped in the rapid phase precipitation and volatile loss, thus exhibiting insufficient ablation property. The as-designed Zr0.92Ta0.04Si0.04O2 coating successfully acquired a near-zero linear recession rate (-0.10 μm/s) after 900 s cyclic ablation (2.4 MW/m2, 15 cycles). Key reasons can be attributed to a continuous sintering promotion and secondary phase precipitation limitation via large lattice distortion, where that of Zr7/8Ta1/16Si1/16O2 lattice exhibits over 200 % increase than Zr7/8Ta1/8O2 lattice.
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.
