Artykuł opisuje i porównuje dwa sposoby otrzymywania drobnych proszków węglika boru z grafenu i amorficznego boru za pomocą mechanicznej aktywacji substratów. Wykorzystano aktywację mechaniczną substratów w młynie planetarnym oraz obrotowo-wibracyjnym. Finalny produkt otrzymano poprzez wysokotemperaturową obróbkę mieszaniny substratów Stwierdzono istotny wpływ warunków obróbki mechanicznej na czystość...
The presence of the water, also in the form of water vapour, can significantly decrease the ceramic material strength. It occurs due to subcritical crack growth phenomenon. Especially susceptible to the stress corrosion are oxide materials. Test were carried out by the Constant Stress Rate method, in the air and the water environment, for the ZrO2 – 10 vol. % Al2O3 composite.
