Ho tloha liphaepheng tsa lipalangoang ho ea likoloing tse ncha tsa matla, ho tloha liontong tse nang le mocheso o phahameng ho ea ho lisathelaete tsa lifofane, thepa e tsejoang e le "daemane ea indasteri" e ngola bocha ka lenyele meeli ea tlhahiso ea sejoale-joale.Li-ceramic tsa silicon carbide, thepa e thata haholo e nang le bothata bo latelang taemane ea tlhaho feela, e baka phetoho e khutsitseng masimong a fapaneng a kang indasteri ea sejoale-joale, li-semiconductor, lifofane le matla a macha ka lebaka la khanyetso ea eona ea mocheso o phahameng, khanyetso e matla ea mahlaseli, le tsamaiso e ntle ea mocheso.
Ha 'masapo a thata' a kopana le tlhahiso e nepahetseng
Haeba li-ceramic tsa setso li le putsoa le porcelain boqaping le mesebetsing ea matsoho, joale li-ceramic tsa silicon carbide li tšoana le lioache tsa Switzerland tse sebelisoang liletsa tse nepahetseng. Bothata ba eona bo feta makhetlo a 3-5 ho feta li-ceramic tse tloaelehileng, 'me bothata bona bo haufi le litaemane tsa tlhaho bo etsa hore ts'ebetso ea ho sebetsa e be joaloka ho betla lipoleiting tsa tšepe - lisebelisoa tse tloaelehileng tsa ho seha lia fela ka lebelo le makatsang nakong ea ho seha. Se thata le ho feta ke hore tlhaho e "thata" ea silicon carbide e etsa hore e be le monyetla oa ho petsoha ka lebaka la phoso e nyane nakong ea ts'ebetso, haholo-holo bakeng sa likarolo tse ling tse nang le mabota a masesaane tse hlokang tlhokomelo e tšoanang le ea mesebetsi ea bonono ea kristale.
Empa tlhoko ea indasteri ea sejoale-joale e susumetsa tsoelo-pele ea theknoloji. Baenjiniere ba fumane hore senotlolo sa ho rarolla bothata bona se ho kopanngoa ha ho tiea le ho tenyetseha: ho boloka litšobotsi tsa mantlha tsa thepa ha u ntse u sebelisa taolo e nepahetseng nakong ea ts'ebetso. Joalo ka baapehi ba maemo a holimo ba tsebang mocheso, mekhoa ea sejoale-joale ea ts'ebetso e laola thepa ena e manganga butle-butle ka taolo e nepahetseng ea mocheso, khatello le maqhubu a ho thothomela.
Linotlolo tse tharo tsa ho notlolla litaemane tsa indasteri
1. Ho chesa ho tobetsa ho bopa
Ena ke e 'ngoe ea mekhoa e tloaelehileng haholo ea ho sebetsana le liserami tsa silicon carbide. Mokhoa ona o beha phofo ea silicon carbide kapa phofo e tsoakiloeng ka har'a hlobo e chesang e hatellang 'me o e sebetsana le sebopeho tlas'a mocheso o phahameng le khatello. E na le katleho e phahameng ea tlhahiso le ho nepahala ha ho bopa, 'me e loketse ho hlahisa lihlahisoa tse kholo tsa silicon carbide ceramic tse kang lisebelisoa tsa ho seha, lipoleiti tsa aluminium tse huloang ka mocheso, jj.
2. Ho bopa ka khoele
Ena ke mokhoa o theko e tlase le o potlakileng oa ho etsa lihlahisoa tsa letsopa tsa silicon carbide. Mokhoa ona o kopanya phofo ea silicon carbide le lintho tse ling tse eketsoang, o li eketsa metsing ho etsa lerōle, ebe o e kenya ka har'a hlobo ea ho bōpela. Ebe, e sebetsoa le ho etsoa ka ho omisa le ho sintering ka mocheso o phahameng, ka potoloho e khutšoanyane ea ts'ebetso le litšenyehelo tse tlase. E loketse ho lokisa likarolo tse matla haholo, tse teteaneng haholo le likarolo tse jarang moroalo.
3. Tšepe ea phofo
Tšebeliso ea tšepe ea phofo ke mokhoa oa ho kopanya le ho bopa phofo ea silicon carbide ka tekanyo e itseng, ebe o e sila mochesong o phahameng le khatellong e phahameng. Mokhoa ona o na le ts'ebetso e bonolo ea tlhahiso, libopeho tse fapaneng tsa sehlahisoa, le ho nepahala ho phahameng ha ts'ebetso, e leng se etsang hore e lokele ho hlahisa lihlahisoa tsa letsopa tse nepahetseng haholo, tse matla haholo le tse sa tsofaleng.
Ho tloha disampoleng tsa laboratori ho isa tlhahisong e kgolo moleng wa tlhahiso, katleho tshebetsong ya di-ceramic tsa silicon carbide e tiisa nnete: ha ho na thepa e ke keng ya sebetswa, ke theknoloji feela e so kang ya senngwa. Ka ho hola ha mahlale a matjha a kang ho sebetswa ha laser le ho sintering ka microwave, thepa ena e kileng ya ba thata haholo e ntse e ntlafala difekthering tse bohlale, e kenya matla a thata a mantlha ho "tlhahiso e bohlale ya China".
Lewatleng le leholo la ho hlahloba sebaka le leqhubu le letala la matla a hloekileng, li-ceramic tsa silicon carbide li ngola tšōmo ea indasteri ea nako ena ka botle ba tsona bo ikhethang ba lintho tse bonahalang. Pontšo ena pakeng tsa ho thatafala le bohlale e ka ba mohlala o sa feleng oa botho bo phunyeletsang meeli ea theknoloji.
