Thepa ea hafnium disilicide
Hafnium silicide ke mofuta oa tšepe ea tšepe e fetohang, e leng mofuta oa komponeng ea methapo e sa sebeliseng letho. Ka lebaka la thepa ea eona e ikhethang ea 'mele le lik'hemik'hale,

Hafnium silicide e sebelisitsoe ka katleho masimong a lisebelisoa tse tlatsetsang tsa semiconductor tsa tšepe, liaparo tse tšesaane tsa filimi, li-module tsa bongata, likarolo tsa motlakase, lisebelisoa tsa motlakase le thepa ea photovoltaic.
Lisebelisoa tsa nano li bonts'a litšobotsi tse khethehileng tsa motlakase, optical, magnetic le thermoelectric, hape li na le boleng ba ts'ebeliso sebakeng sa catalysis.
Likarolo tsa hafnium disilicide
Sehlahisoa se na le bohloeki bo phahameng, boholo ba phatsa e nyane, kabo ea junifomo, sebaka se seholo se holimo le ts'ebetso e phahameng ea bokaholimo.

Lisebelisoa tsa letsopa, tlhahiso ea likarolo tse fapaneng tse phahameng tsa mocheso o phahameng le likarolo tse sebetsang.

Ts'ebeliso ea Hafnium silicide ho itokiseng ha thepa
1. Litokisetso tsa SiC - hfsi2 - TaSi2 anti ablation barbotage. Carbon fiber e matlafalitseng k'habone (C / C) e entsoe ka mofuta o mocha oa thepa e nang le mocheso o phahameng o kenang ka khabone e le matlafatso le pyrolytic carbon joalo ka matrix. Ka lebaka la matla a eona a phahameng haholo a mocheso o phahameng, ho hanyetsa ablation le khohlano e ntle le thepa ea ho apara, lilemong tsa bo-1970, United States e ile ea etsa mosebetsi oa ho etsa lipatlisiso ka likarolo tsa C / C bakeng sa meaho e futhumetseng, e ileng ea etsa likarolo tsa C / C ho tsoa ho lisebelisuoa tse chesang tsa mocheso oa mocheso. Joalo ka thepa ea mochini o futhumatsang, likarolo tsa C / C li ka sebelisoa linthong tsa sebopeho sa enjene ea turbine ea khase, sekoaelo sa nko ea sepakapaka, bohale ba lepheo, joalo-joalo boholo ba likarolo tsena li sebetsa maemong a phahameng a mocheso le oxidation.
Leha ho le joalo, likarolo tsa C / C li bonolo ho li kopanya 'me hangata li ke ke tsa sebelisoa moeeng oa oxidation o kaholimo ho 400 ℃. Sena se hloka tšireletso e nepahetseng ea anti-oxidation bakeng sa likarolo tsa C / C, 'me ho hlophisoa ha seaparo se khahlanong le oxidation ke e' ngoe ea mehato e meholo ea ts'ireletso. Liphetho li bonts'a hore khanyetso ea ablation ea likarolo tsa C / C e ka ntlafatsoa le ho feta ha Zr, HF, Ta, TiB2 le lirafshoa tse ling tse kenyelletsoang li eketsoa ka har'a matrix ea khabone. Bakeng sa ho utloisisa tšusumetso ea HF le TA ho litheko tse tlase tsa likarolo tsa C / C, SiC - hfsi2 - TaSi2 anti-ablation bar e hlophisitsoe ka mokhoa oa ho kenella. Ts'ebetso ea ablation ea seaparo e lekantsoe ke sesebelisoa sa ablation sa oxyacetylene.
2. Ho hlophisoa ha sesebelisoa sa elektroniki sa motlakase. E kenyelletsang anode, lera le ntšang khanya, cathode le sekoaelo sa ho paka se koahelang lera le hlahisang khanya le cathode e ho anode, sekoaelo sa ho paka se na le lera la silicon nitride le mokoallo o thehiloeng holim'a silicon lera la carbide; thepa ea mokoallo e kenyelletsa silicide le oxide ea tšepe, 'me silicide e khethoa ho chromium silicide, tantalum disilicide, Hafnium silicide, titanium disilicide le disilicide The oxide ea tšepe e khethoa ho tsoa ho magnesium oxide, aluminium oxide, titanium dioxide, zirconia, hafnium dioxide le tantalum pentoxide. Bophelo ba sesebelisoa se hlahisang leseli la manyolo bo bolelele. Moqapi o boetse o fana ka mokhoa oa boitokisetso oa sesebelisoa sa organic electroluminescent.

3. Ho qaptjoa ha karolo ea motlakase oa motlakase oa Si Ge. Sesebelisoa sa motlakase sa SiGe se entsoe ka lera la eleketrode, lera la motlakase oa SiGe le mokoallo o pakeng tsa lera la eleketrode le lera la motlakase oa SiGe. Lera la mokoallo ke motsoako oa silicide le nitride ea silicon, 'me silicide ke bonyane e' ngoe ea molybdenum silicide, tungsten silicide, cobalt silicide, nickel silicide, niobium silicide, zirconium silicide, tantalum silicide le Hafnium silicide. Khokahano ea likaroloana tsa thermoelectric tsa silicon germanium e hokahane hantle, ha ho na mapetso le ts'ebetso e hlakileng ea phallo e fumanehang ho interface, khokahano ea ho ikopanya e nyane, naha ea puisano e futhumetseng e ntle, e ka mamella teko ea ho potlakisa mocheso o phahameng oa nako e telele. . Ntle le moo, mokhoa oa ho itokisa o na le melemo ea ts'ebetso e bonolo, ts'epahalo e phahameng, theko e tlase, ha ho na lisebelisoa tse ikhethang ebile e loketse tlhahiso e kholo.

4. Ho ile ha lokisetsoa mofuta o koahelang mocheso o phahameng o khahlanong le ho kena moea. Filimi e nang le likarolo tse ngata e khetholloa ka hore barbotage e entsoe ka tšepe e sa sebetseng, carbide e sa sebetseng, 'me khalase e koahela ke 10 μ m ~ 50 μ M. Ts'epe e ts'ebetsong ke e' ngoe kapa ho feta ea molybdenum, tantalum, zirconium le hafnium; carbide e sa sebetseng e entsoe ka silicon carbide le e 'ngoe kapa tse' maloa tsa tantalum carbide, zirconium carbide le hafnium carbide; komponeng intermetallic e entsoe ka e le 'ngoe kapa ho feta ea molybdenum silicide, tantalum silicide, zirconium silicide, Hafnium silicide, tantalum carbide, zirconium silicide le hafnium carbide; sebopeho sa kristale ea seaparo se thehiloe ke li-nanoparticles tsa amorphous le / kapa polycrystalline.
