Oxidation behavior of SiBCN-Zr composites at 1500 °C prepared by reactive spark plasma sintering
چکیده انگلیسی
The oxidation behavior of SiBCN-Zr composites prepared through incorporating sol-gel processing with spark plasma sintering (SPS) was studied in detail. It is indicated from results that a dense amorphous SiO2 film was formed on the samples superficially in the course of oxidation, which avoided the sample from being further oxidized. The oxidation of ZrB2 would boost the oxygen to be diffused, which aggravates the oxidation. Amorphous SiO2 would fill up the pores and avoid ZrB2 particles from being further oxidized. A preferable anti-oxidation behavior was also manifested by BN(C) arising from the formation of B2O3 phases.
