Ablation-Resistance of Combustion Synthesized TiB2–Cu Cermet
Zhang, Xing-Hong, Han, Jie-Cai, He, Xiao-Dong, Yan, Cheng, Wang, Bao-Lin, & Xu, Qiang (2005) Ablation-Resistance of Combustion Synthesized TiB2–Cu Cermet. Journal of the American Ceramic Society, 88(1), pp. 89-94.
TiB2–Cu ceramic–metal composites were prepared by combustion synthesis of elemental titanium, boron, and copper powders. The synthesized product consisted of two phases: TiB2 and copper. The addition of copper improved the strength and fracture toughness, thermal expansion coefficient, and thermal conductivity of TiB2. Thermal shock and ablation resistances of TiB2–Cu composites were studied using a plasma torch arc heater.Monolithic TiB2 failed catastrophically when the plasma arc flow reached the specimen surface. However, no cracks were found on the ablation surface of the TiB2–Cu ceramic–metal composites. The fractional mass loss was 4.09% for a TiB2– 40Cu composite, which was close to the traditionalW/Cu alloys. Volatilization of metal binder and mechanical erosion of TiB2 were observed to be the major ablation mechanisms. An ablation process model is proposed for the TiB2–Cu composites.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
