Sinter plate ke sesebelisoa se sebelisetsoang ho jara le ho tsamaisa lesea la ceramic le chesitsoeng ka sebōping sa ceramic.E sebelisoa haholo-holo ka sebōping sa ceramic e le sejari sa ho jara, ho kenya mocheso le ho tsamaisa lirafshoa tse chesitsoeng.Ka eona, e ka ntlafatsa lebelo la conduction ea mocheso oa poleiti ea sintering, e etsa hore lihlahisoa tsa sintering li futhumale ka mokhoa o ts'oanang, ho fokotsa tšebeliso ea matla ka katleho le ho potlakisa lebelo la ho thunngoa, ho ntlafatsa tlhahiso, e le hore lihlahisoa tse tšoanang tsa sebōpi se chesang li se na mebala le melemo e meng.
Lisebelisoa tsa Corundum mullite li na le khanyetso e phahameng ea mocheso oa mocheso le matla a mocheso o phahameng, le botsitso bo botle ba lik'hemik'hale le ho hanyetsa ho apara.Ka hona, e ka sebelisoa khafetsa ka mocheso o phahameng haholo, haholo-holo bakeng sa sintered magnetic cores, ceramic capacitors le insulating ceramics.
Lihlahisoa tsa sintering ke lihlahisoa tsa sintering tse laminated.Karolo e 'ngoe le e 'ngoe ea poleiti ea sintering hammoho le boima ba sehlahisoa e ka ba 1kg, ka kakaretso ke l0 layer, kahoo poleiti ea sintering e ka ba le khatello e phahameng ea lik'hilograma tse fetang leshome.Ka nako e ts'oanang, ho jara ts'ebetso ha u falla le ho ferekana ha lihlahisoa tsa thepa le ho laolla, empa le lipotoloho tse ngata tse batang le tse chesang, ka hona, ts'ebeliso ea tikoloho e thata haholo.
Ntle le ho nahana ka ho sebelisana ha lintlha tse tharo, phofo ea alumina, kaolin le mocheso oa calcination kaofela li ama ho hanyetsa mocheso oa mocheso le ho phalla.Ho hanyetsa mocheso oa mocheso ho eketseha ka ho eketsoa ha phofo ea alumina, 'me e fokotseha ka ho eketseha ha mocheso oa mollo.Ha dikahare tsa kaolin li le 8%, ho hanyetsa mocheso oa mocheso ke ho tlaase ka ho fetisisa, ho lateloa ke dikahare tsa kaolin tsa 9.5%.The creep fokotseha ka tlatsetso ea alumina phofo, 'me creep ke tlaase-tlaase ha dikahare tsa kaolin ke 8%.Mocheso o phahameng ka ho fetisisa ke 1580 ℃.E le hore ho nahanela ho hanyetsa mocheso oa mocheso le khanyetso ea creep ea thepa, liphello tse ntle ka ho fetisisa li fumanoa ha aluminium content e le 26%, kaolin ke 6.5% le mocheso oa calcination ke 1580 ℃.
Ho na le lekhalo le itseng pakeng tsa likaroloana tsa corundum-mullite le matrix.Hape ho na le mapheo a pota-potileng likaroloana, tse bakoang ke ho se lumellane ha coefficient ea ho atolosa mocheso le modulus elastic pakeng tsa likaroloana le matrix, e leng se bakang li-microcracks lihlahisoa.Ha palo ea katoloso ea likaroloana le matrix e sa lumellane, kakaretso le matrix ho bonolo ho aroloa ha li futhumatsoa kapa li pholile.Ho thehoa lekhalo pakeng tsa bona, ho fella ka ponahalo ea li-microcracks.Ho ba teng ha li-micro-cracks tsena ho tla lebisa ho senyeha ha thepa ea mochine, empa ha thepa e le tlas'a mocheso oa mocheso.Sekheong se lipakeng tsa kakaretso le matrix, e ka bapala karolo ea "buffer zone", e ka amohelang khatello e itseng 'me ea qoba khatello ea maikutlo ntlheng ea crack.Ka nako e ts'oanang, ho phatloha ha mocheso oa mocheso ka har'a matrix ho tla emisa lekhalo pakeng tsa likaroloana le matrix, e leng se ka thibelang ho ata ha crack.Ka hona, ho hanyetsa mocheso oa mocheso oa thepa ho ntlafatsoa.
