Аннотация:The features of oxidation of ultra-high-temperature ceramic material HfB2-30 vol.%SiCmodified with 1 vol.% graphene as a result of supersonic flow of dissociated CO2 (generated with theuse of high-frequency induction plasmatron), as well as under the influence of combined heating byhigh-speed CO2 jets and ytterbium laser radiation, were studied for the first time. It was found thatthe addition of laser radiation leads to local heating of the central region from ~1750 to ~2000–2200 C;the observed temperature difference between the central region and the periphery of ~300–550 C didnot lead to cracking and destruction of the sample.
