3. Ha o ka khethaBoron carbide
3.1 bakeng sa lits'ebetso tsa boima ba 'mele
Boron Cramide ke e 'ngoe ea makhethe a bobebe a mahlale, a e etsa a phethahetse ho fokotsa boima ba ho fokotsa boima ba ho sekisetsa ho sekisetsa.
3.2 bakeng sa ts'ireletso e phahameng ea boloi
B4Cke khetho e ntle ka ho fetisisa ea:
Li-plate tsa 'mele tsa' mele
Lihlopheng tsa Ts'ireletso
Lihlomo tsa koloi
Tšireletso bakeng sa helikopthara le lifofane
Ho thatafala ha eona tse sa tsejoeng ho e thusa ho thibela likulo tse phahameng tsa vaelocity tse nang le boima bo fokolang.
3.3 Bakeng sa tikoloho e feteletseng ea tikoloho
Boron carbidee hlahisa:
Likarolo tsa moaparo oa indasteri
Metsoako ea pompo ea pompo ea Slurry
Li-sandblate li-nozzles
Lisebelisoa tsa Boenjiniere tsa Nuclear
Ho roala khafetsa ho fella ka ho phela ka mokhoa o sa tsoa sebetsa le ho senya maemo a mabe.
4. Ha o ka khethaSilicon carbide
4.1 Bakeng sa likopo tse phahameng tsa boitšoaro bo phahameng
Silicon carbidee loketse:
Dikarolo tsa bohlola
Motheo oa mocheso
Semiconductor Lisebelisoa tsa Ts'ebetso ea Semicondtor
Ke ka potlako e senya mocheso mme e khona ho mamella ho sesa ha mocheso o feteletseng ntle le ho senyeha.
4.2 Bakeng sa merero ea indasteri e theko e boima
Sice ratoa hobane e fana ka ts'ebetso e ntle ka litšenyehelo tse tlase:
Nozzles
Likopano
Li-li-tiges tsa meralo
Thepa ea Kiln
Likarolo tsa koloi
4.3 Bakeng sa maemo a hlokang ho tšoha haholo
SIC ha e nyane ho feta B₄c, e etsa hore e tšoarelle litšusumetso, ho sisinyeha le ho sisinyeha ho futhumatsang.
5. Papiso ea theko
Ha litheko tsa sebele li itšetlehile ka bohloeki, boholo le ts'ebetso ea tšebeliso:
Boron carbidee ngata haholoHo na le theko e boima ka lebaka la lintho tse tala tse theko e boima le ho siling e holofetseng.
Koloi ea ka ea silicon e theko e boima haholo, haholo bakeng sa likarolo tse kholo kapa tlhahiso e kholo.
B₄c ke khetho e holimo ea ho fihlela ts'ebetso e kholo ka litšenyehelo tsohle.
Haeba karolelano ea theko ea theko e bohlokoa, sic hangata ke khetho e holimo.

8. Conclusion
Boron carbide le silicon Carbisix ea sirifin ke li-ceramics tse phahameng haholo, empa li tiisa libakeng tse ikhethileng.
Boron Carbide ha e reroe e ratoang ka thata
Silicon carbideE na le botsitso bo botle ba bo futhumatsang, ho thata, le katleho ea litšenyehelo, ba e etsa boitsebiso bo loketseng bakeng sa likopo tsa mocheso le tse phahameng.
Seteishene se setle ka ho fetisisa sa kopo ea hau se khethoa ke litlhokahalo tse khethehileng. Bakeng sa lits'ebetso tse ngata, ho leka-lekanya boima, ho leka-thata, ho ba thata, ho etsa lintho tse futhumatsang, ho ba thata, ho ba le moralo oa lichelete ho bohlokoa ho khetha lintho tse ntle haholo.
