Ceramic Composite Based on Boron Nitride with Enhanced Resistance to Ion Bombardment for Application in Hall Thruster

摘要

A composition of composite nanostructured material with enhanced resistance to erosion caused by ion and electronsputtering for application in a Hall thruster is considered. A multistage process of composite production is described; full size prototypes of a final product in the form of insulation rings of accelerating channel are produced. Experimental studies on functional and mechanical properties of the obtained material are carried out. Results of analysis of the microstructure and elemental composition of the composite show prospects of its application in a Hall thruster.
