Khanyetso ea oxidation ea likarolo tse nepahetseng tsa ceramic le tikoloho ea eona ea ts'ebeliso
Likarolo tsa ceramic tse nepahetseng ke lisebelisoa tsa bohlokoa tse sebetsang hantle indastering ea sejoale-joale, 'me thepa ea bona e ikhethang ea' mele le ea lik'hemik'hale e tlisitse liphetoho tse ngata masimong a mangata. Har'a bona, khanyetso ea oxidation ke e 'ngoe ea litšobotsi tse hlahelletseng tsa likarolo tse nepahetseng tsa ceramic, tse bohlokoa haholo maemong a feteletseng.
Ho hanyetsa oxidation ea likarolo tse nepahetseng tsa ceramic
Lisebelisoa tsa ceramic tse nepahetseng, tse kang alumina, silicon nitride, silicon carbide, joalo-joalo, li tsejoa ka thepa ea tsona e babatsehang ea antioxidant. Lisebelisoa tsena li ka boloka lik'hemik'hale tse tsitsitseng tlas'a mocheso o phahameng le tikoloho e phahameng ea oxidation, 'me ha ho bonolo ho itšoara ka oksijene, kahoo ho qoba ho senya, ho senya le ho senyeha ha ts'ebetso ea thepa. Khanyetso ena e babatsehang ea oxidation e bakoa haholo-holo ka mokhoa o tsitsitseng oa kristale le matla a lik'hemik'hale tsa lik'hemik'hale ka har'a thepa ea ceramic, e etsang hore e khone ho boloka botsitso ba nako e telele le ho tšepahala libakeng tse thata.
Tikoloho ea ts'ebeliso ea bohlokoa
1. Sepakapaka
Lebaleng la aerospace, khanyetso ea oxidation ea likarolo tse nepahetseng tsa ceramic e bohlokoa haholo. Lienjine tsa lifofane le lifofa-sebakeng li hloka ho mamella mocheso o phahameng haholo le likhase tse nang le oxidizing nakong ea sefofane sa lebelo le phahameng. Likarolo tse kang likamore tse tukang mollo, li-nozzles le li-turbine tse entsoeng ka thepa ea ceramic e nepahetseng li ka boloka ts'ebetso e tsitsitseng mochesong o phahameng, ka katleho li thibela oxidation le corrosion, le ho netefatsa ts'ebetso e tloaelehileng ea enjene le sepakapaka.
2. Lekala la matla
Sebakeng sa matla, khanyetso ea oxidation ea likarolo tse nepahetseng tsa ceramic le eona e phetha karolo ea bohlokoa. Ka mohlala, ka thepa e phahameng ea mocheso e kang li-turbine tsa khase le li-boilers tse chesitsoeng ka mashala, likarolo tse kang likarolo tsa ho futhumatsa mocheso le li-filters tse entsoeng ka thepa ea ceramic li ka hanela ho senyeha ha mosi oa mocheso o phahameng, ho sireletsa mohaho o ka hare oa thepa le ho ntlafatsa matla a matla. Ho feta moo, lebaleng la eneji ya nyutlelie, disebediswa tsa ceramic tse nepahetseng le tsona di sebediswa ka bophara ka hara mohatsela wa mocheso le lera le sireletsang la diactor tsa nyutlelie ho netefatsa tshebediso e bolokehileng ya eneji ya nyutlelie.
3. Indasteri ea lik'hemik'hale
Indastering ea lik'hemik'hale, liphetoho tse ngata tsa lik'hemik'hale le lits'ebetso li hloka ho etsoa ka mocheso o phahameng, khatello e phahameng le libaka tse matla tse senyang. Likarolo tse nepahetseng tsa ceramic, tse nang le khanyetso e ntle ea oxidation le khanyetso ea kutu, ke lisebelisoa tsa bohlokoa libakeng tsena. Ka mohlala, lisebelisoa tsa lik'hemik'hale tse nang le acid e matla le alkali corrosion, likarolo tse kang liphaephe, li-valve le lipompo tse entsoeng ka thepa ea ceramic li ka thibela ka katleho ho senya le ho lutla, ho netefatsa polokeho le botsitso ba tlhahiso ea lik'hemik'hale.
sephetho
Ka kakaretso, khanyetso ea oxidation ea likarolo tse nepahetseng tsa ceramic ke e 'ngoe ea thepa ea eona e ntle haholo, e bapalang karolo ea bohlokoa indastering ea sefofane, matla le lik'hemik'hale. Ka tsoelopele e tsoelang pele ea mahlale le thekenoloji le katoloso e tsoelang pele ea lits'ebetso, thepa ea antioxidant ea likarolo tse nepahetseng tsa ceramic e tla tsoela pele ho ameha le ho ntlafatsoa, e tlisang boqapi le tsoelopele mafapheng a mangata. Nakong e tlang, ka nts'etsopele e tsoelang pele ea mahlale a lintho tse bonahalang le theknoloji ea ho lokisa, re na le lebaka la ho lumela hore likarolo tse nepahetseng tsa ceramic li tla bontša botle ba tsona bo ikhethang le boleng ba tsona libakeng tse ngata.
