I-Hafnium boride (HfB₂) iyimpahla ye-ceramic eyaziwa ngezakhiwo zayo ezingavamile, okuhlanganisa ubulukhuni obuphezulu, indawo encibilikayo ephezulu, kanye nokuhamba kahle kwe-thermal kanye nogesi. Iyingxenye yomndeni wezitsha zobumba ezisezingeni eliphezulu kakhulu (ama-UHTC), ezisetshenziswa ezindaweni ezeqisayo ezifana ne-aerospace nezinhlelo zokusebenza zokuvikela.

Incazelo Yomkhiqizo

I-Hafnium diboride iwuhlobo lwekristalu empunga futhi ine-metallic luster, ene-conductivity kagesi ephezulu kanye nempahla yamakhemikhali ezinzile. Ngaphandle kwalokho, akusabeli neze nawo wonke ama-reagents amakhemikhali (ngaphandle kwe-Hf) kumazinga okushisa angaphakathi. Lona, uhlobo olusha lwensimbi ye-ceramic esebenza kahle kakhulu esezingeni eliphezulu njengephuzu lokuncibilika, izinga eliphezulu le-thermal conductivity, i-inoxidizability, njll., isetshenziswa ikakhulukazi emikhakheni efana ne-super high-temperature ceramics, i-high-speed air air cone kanye ne-aerospace, njll.

Isicelo

I-Hafnium diboride iyikristalu ecwebezelayo empunga-mnyama ukwakheka kwayo kwekristalu okuyingxenye yesistimu ene-hexagonal. Njengempahla ye-ceramic yokushisa ephezulu kakhulu esezingeni eliphezulu, i-hafnium diboride (HfB2) inendawo ephezulu yokuncibilika (3380 ℃), ivamise ukusetshenziswa ezintweni ezilwa nokukhipha umoya endaweni ene-oxidation ephezulu futhi inezici zobulukhuni obuphezulu, i-modulus ephezulu, ukuqhutshwa kwe-thermal ephezulu kanye nokuhamba okuphezulu. Isetshenziswa kabanzi kuma-coatings angagugi, izinto eziphikisayo, amathuluzi okusika kanye nezinhlelo zokuvikela ukushisa kwe-aerospace nezinye izinkambu.

Isevisi esingayinikeza

1) Inkontileka esemthethweni ingasayinwa

2) Isivumelwano sokugcinwa kuyimfihlo singasayinwa

3) Isiqinisekiso sokubuyiselwa imali sezinsuku eziyisikhombisa

Okubaluleke nakakhulu: asikwazi ukunikeza umkhiqizo kuphela, kodwa isevisi yesixazululo sobuchwepheshe!
