Beschreibung
Zusammenfassung:FIELD: construction. ^ SUBSTANCE: composite ceramic material is produced on the base of refractory oxygen-free and oxide compounds to use in conditions which require high rigidity, firmness and oxidation stability: for manufacturing cutting tools, thermowells for temperature control in molten metals, nozzle extensions for air sand blowers, in gas and oil industry. Composite ceramic material containing ZrB2 and ZrO2, in the fist version additionally contains TiN and Y2O3 with following mixture ratio: wt %: ZrB2 20-40, Y2O3 4.5-10, TiN 10-25.5, ZrO2 - the rest, and in the second variant - ZrN and Y2O3 with following mixture ratio: wt %: ZrB2 20-40, Y2O3 4.5-10, ZrN 10-25.5, ZrO2 - the rest. ^ EFFECT: high resistance to oxidation and erosion and resistance to thermal shocks at temperature gradient up to 2000 K in conditions of oxidising flow action. ^ 2 cl, 3 ex, 1 tbl, 1 dwg
