A METHOD FOR EUTECTIC CERAMICS POWDER PRODUCTION BASED ON BORON CARBIDE BY THE METHOD OF CENTRIFUGAL PLASMA SPRAYING

摘要

A method for eutectic ceramics powder production based on boron carbide by the method of centrifugal plasma spraying includes dosing, a mixture of B4C and TiB2 initial powders mixing and compressing in a ratio of 65 wt. % of the B4C and 35 wt. % of the TiB2, sintering and grinding of the workpieces. Workpieces sintering is carried out at a temperature of 1400-1600 °C in vacuum, and then crushed by the centrifugal plasma spraying.
