| Summary: | The conditions of in ultrasound (US) transmission through a nanodispersed powder (NP) and possible effects of US-action at compacting of NP ZrO2 -Y20,j are analyzed. These effLcts include agglomerate crushing, NP particle activation under the conditions of acoustic flows; dense NP compacting with the preservation ofa compact nanostructure in the absence of acoustic flows. It was shown that the result of 13S action was defined by the compacting pressure P and ItS intensity level I, the values of which were divided into the ranges by the critical parameters Pu and ic. NP transfers from the state of gas-dispersed medium to the state of a solid porous body at P = Pc, and I (characterizes the threshold of acoustic flows appearance in the powder body В фонде НТБ ТПУ отсутствует |
