Oxidation behavior of boron-containing (Zr,Ti)CxBy solid solution ceramics at 1600 °C in air

Journal of Advanced Ceramics, 2023
Multicomponent boron-containing carbide coatings (i.e., (Zr,Ti)CxBy) on a C/C composite show good ablation resistance. However, the high-temperature oxidation behavior of this new type of boron-containing (Zr,Ti)CxBy solid solution ceramics has not been ...

SiC-IrSi3 for High Oxidation Resistance [PDF]

Materials, 2019
SiC is a material with excellent mechanical and thermal properties but with a high production cost. Obtaining SiC by reactive infiltration is an attractive method with a much lower cost than the traditional sintering process. However, the reactive infiltration process presents a serious problem, which is the high residual silicon content, which ...

Oxidation behavior of high Cr white iron composites reinforced with TiC and nonstoichiometric TiCx in air at 600 °C

Journal of Materials Research and Technology, 2023
High Cr white irons (HCWIs) are often used as high-temperature components exposed to the temperatures exceeding 500 °C. Improving oxidation resistance of HCWI components is necessary for engineering applications. In the present study, oxidation behaviors

Effects of Oxidation on Oxidation-Resistant Graphite [PDF]

, 2015
The Advanced Reactor Technology (ART) Graphite Research and Development Program is investigating doped nuclear graphite grades that exhibit oxidation resistance through the formation of protective oxides on the surface of the graphite material. In the unlikely event of an oxygen ingress accident, graphite components within the VHTR core region are ...

Triarylmethane Fluorophores Resistant to Oxidative Photobluing [PDF]

Journal of the American Chemical Society, 2018
Spectral stability of small-molecule fluorescent probes is required for correct interpretation and reproducibility of multicolor fluorescence imaging data, in particular under high (de)excitation light intensities of super-resolution imaging or in single-molecule applications.

Improving the high-temperature oxidation resistance of TiB2 thin films by alloying with Al

Acta Materialia, 2020
Refractory transition-metal diborides (TMB2) are candidates for extreme environments due to melting points above 3000 °C, excellent hardness, good chemical stability, and thermal and electrical conductivity. However, they typically suffer from rapid high-

Oxidation Behavior of Quaternary Co-20Re-25Cr-3Si Alloy at Laboratory Air

Frontiers in Materials, 2021
The iso-thermal oxidation of the quaternary Co-20Re-25Cr-3Si alloy at 1,000–1,200 C under laboratory air for 24 h has been studied. The oxidation kinetics at 1,000–1,200 C follow parabolic law perfectly and the value of oxidation activation energy is 220.
