Kopo eaBoron carbide
1. Boron carbide e sebelisoa e le ho pona
Ts'ebeliso ea boron carbide e le ho akheha haholo ho sesa le ho pola sa safire. Har'a thepa ea Superhard, ho thata la sebotsoana la borena le molemo ho feta la aluminum oxide le siranide Safire ke thepa e ntle ka ho fetisisa ea semiconductor gan / al 2 o3 e bobebe Ho boreleli ha bokaholimo bo holimo haholo 'me ho tlameha ho ba bonolo haholo ha ho na thuso. Ka lebaka la matla a phahameng le thata phahameng la kristap ea sapphire (Mohs Harstal 9), e tlisitse mathata a maholo ho ea lokisa likhoebo.
Ho tloha ponong ea thepa le ho cheka, lisebelisoa tse ntle tsa ho sebetsa le ho sesetsa likristale tsa sapphire, likri tsa silise, boron carbide, silika. Ho thata ha daemane ea maiketsetso e holimo haholo (Mohs Harness. Ka mor'a ho kuta mario a silion, lekhotla le boima hangata le phahame 'me sephara ke mafutsana; Leha ho le joalo, ho thatafala ha Sinela ha hoa lekana (ho matla a 7), 'me matla a ho fanyeha a futsanehile, e leng boima ba nako le mosebetsi o boima. Ka hona, Boron chide e nkileng (Mohs Harness 9.3) e fetohile boitsebiso bo loketseng ka ho fetisisa bakeng sa ho sebetsa le ho silafatsa likristale tse tjaroang tsa safire
Ho ka ba molemo ho bolela hore ha Boron Claride o kaholimo ho 600 ° C, bokaholimo bo tla e nolofalletsa ho ts'oaroa haholo likolong tsa metsi tse ntle. Leha ho le joalo, thepa ena e thibela B4C hore e se ke ea oxidased hape, ho e etsa hore e be le melemo e ikhethang ea ho sebelisa thepa ea ho ithuta.
2. Sesebelisoa ka thepa ea ho rekoloha
Boron Carbide e na le litšobotsi tsa anti-oxidation le khatello e phahameng ea mocheso. Ka kakaretso e sebelisoa e le thepa e hlophisitsoeng hantle ebile e sebelisoa haholo masimong a fapaneng a metallirgy, joalo ka setofo sa tšepe le thepa ea kiln.
Ka litlhoko tsa ho boloka matla le phokotso ea ts'ebeliso ea tšepe le tšepe ea tšepe e tlase le nts'etsopele ea khase. Hona joale, ts'ebetso ea litene tsa khabone tsa carbon-Carbon ka kakaretso ke ho ntlafatsa sebopeho sa khabone, ho ntlafatsa sebopeho sa matrice sa matrice. Har'a tsona, khaba e qapiloeng ea khabone e entsoeng ka carbide ea indasteri ea Boron ea Indasteri le e nang le peterole e sentsoeng. Pofo ea phofo e ntšo, e sebelisoang joalo ka mohloli oa carbon le antioxidant bakeng sa magnesia-carbon litene, e fihletse litholoana tse ntle.
Kaha boron carbide e tla nolofatsa ho isa tekanyong e itseng ka mocheso o phahameng, e ka kopanngoa le bokantle ba likaroloana tse ling tsa thepa. Le ha sehlahisoa se ntse se lopolloa, filimi ea pohi ea B2O3 e holim 'a bokaholimo ho ka etsa tšireletso e itseng' me u bapale karolo e thibelang bothibela. Ka nako e ts'oanang, hobane likhoele tsa Clintar li hlahisitsoe ke karabelo ea litheko, 'me ho fokotseha ha makhoaba a hlahisang le ho fokotsa mapetso.
3. Lisebelisoa tse sebelisoang ho ntlafatsa ts'ireletso ea naha
Ka lebaka la thata ea eona e matla, matla a phahameng, matla a khoheli a mangata, le boemo bo phahameng ba ho hanyetsa thepa e bobebe. Ke thepa e ntle ka ho fetisisa ea bullet e ntle ka ho fetisisa bakeng sa ts'ireletso ea sefofane, likoloi, lihlomo tsa lihlomo le 'mele ea batho; Hajoale,Linaha tse lingo entse lipatlisiso tse theko e tlase ea bosholu ba li-carbide tsa li-anti-sharini, li ikemiselitse ho sebelisa ts'ebeliso e kholo ea lihlomo tsa bolo ea Boron carbing in inction.
4. Sebetsa indastering ea nyutlelie
Boron Carbide e na le karolo e phahameng ea borena le ea nang le moea o mongata, 'me o amoheloa ka har'a naha ea baeti haholo. Har'a bona, karolo ea mocheso ea boron-10 iskotope e phahame hoo e ka bang 347 ×,5-24 cm e kang Gadolinium, mme ke cadmium neutron e sebetsang hantle. Ntle le moo, bo nts'etsopele ea borena e na le lisebelisoa tsa moea, tse hlahang mamati a futhumetseng, kahoo ha ho na le lisebelisoa tse tlase tse nang le taolo ea borena.
Ka mohlala, indastering ea nyutlelie, motlalehi oa boiketlo ba mocheso o phahameng o sebelisa boron e fumanang sistimi ea bolo ea bolo e le sistimi ea bobeli ea ho koala. Haeba ho na le kotsi, ha sistimi ea pele ea ho koala e hloleha, ho koala bolo ea hau ea bochaba. Ts'ebetso ea mantlha ea Corebide ea Boron Carbide ka mocheso o futhumetseng ea khase ke ho laola matla le polokeho ea motlatsi. Setetsoana sa khabone se kenngoa ka boron carbide e amohela sengoliloeng, se ka fokotsang sejana sa neutron sa sejana sa racor.
