Maemong a indasteri a mocheso o phahameng, ts'ebetso ea likarolo tsa sebopeho e khetholla ka kotloloho katleho ea tlhahiso, polokeho le taolo ea litšenyehelo.Mahlaseli a silicon carbide (SiC)Li hlahile e le tse fetolang lintho, li nkela thepa ea setso joalo ka tšepe le li-ceramic tsa alumina sebaka ka ho hanyetsa mocheso o phahameng ka mokhoa o ikhethang, ho hanyetsa mafome le botsitso ba sebopeho. Li etselitsoe ho tšoarella le ho ikamahanya le maemo, mahlaseli a rona a SiC a ikhethileng a sebetsana le litlhoko tse fapaneng tsa indasteri, a fana ka ts'ebetso e tšepahalang maemong a thata ka ho fetisisa.
Tšebeliso ea mahlakore a silicon carbide e akaretsa mefuta e mengata ea liindasteri tse nang le mocheso o phahameng, e leng se etsang hore e be likarolo tsa bohlokoa tsa bohlokoa. Haholo-holo, a sebelisoa haholo e le meaho e jarang mojaro le litšehetso tsa thepa ea ka tlung ea li-oven li-oven tsa liindasteri, ho kenyeletsoa li-oven tsa tunnel, li-oven tsa shuttle, li-oven tsa roller le li-oven tsa bell. Mahlakore ana a jara boima ba lihlahisoa likoloing tsa oven 'me a tšehetsa meaho e hanyetsang marulelo a oven, e netefatsa ts'ebetso e tsitsitseng esita le tlas'a ho besoa ka nako e telele mochesong o fihlang ho 1380℃. A loketse haholo lits'ebetso tsa ho sintering li-ceramics tsa tekheniki, phofo ea ceramic ea elektroniki, lisebelisoa tsa bohloeki, lisebelisoa tse ntle le tse mpe tsa betri ea lithium, le indasteri ea lisebelisoa tse hanyetsang.
Kantle ho ditshebediso tsa ontong, mahlasedi a SiC a ipabola maemong a mang a tlhokeho e kgolo. Khanyetso ya ona e ntle ya oxidation le botsitso ba dikhemikhale di etsa hore e be a loketseng ho sebediswa diboiler tsa motlakase wa mocheso, ho sintering ha tshepe le ditshebetso tsa ho petsoha ha dikhemikhale, moo a hanelang kgoholeho ya metsi a tswang dikhase tse oxidating le tse nang le asiti. Ho feta moo, bohloeki ba ona bo phahameng le matla a sebopeho di nolofalletsa tshebediso ya ona disebedisweng tsa mocheso o phahameng tsa sefofane le tlhahiso ya semiconductor, e leng se tshehetsang ntshetsopele ya diindasteri tse ntseng di hola tsa mawa. Ha di bapiswa le thepa ya setso, mahlasedi a SiC a na le bophelo ba tshebeletso bo bolelele ka makgetlo a 5-6, e leng se fokotsang haholo makgetlo a tlhokomelo le ditjeo tsa ho nkela sebaka.
Rea utloisisa hore projeke e 'ngoe le e 'ngoe ea indasteri e na le litlhoko tse ikhethang, ke ka lebaka leo re fanang ka litharollo tsa silicon carbide square beam tse ikhethileng ka botlalo. Tšebeletso ea rona ea ho iketsetsa e akaretsa karolo e 'ngoe le e 'ngoe ea bohlokoa ho lumellana le litlhoko tsa hau tse ikhethileng. Taba ea pele, ho iketsetsa boholo: re hlahisa maballo a boholo bo pakeng tsa 30 × 30mm le 120 × 120mm le ho feta, ka botenya ba lebota bo ka fetoloang ho latela litlhoko tsa hau tsa ho jara mojaro. Re boetse re fana ka mechini e khethehileng, joalo ka masoba a ho cheka, masoba a malelele kapa likheo, ho netefatsa kopanyo e phethahetseng le lisebelisoa tsa hau tse teng.
Taba ea bobeli, ho fetola thepa: re fana ka likhetho tsa reaction sintered (SiSiC/RSiC) le recrystallized (RC-SiC), tse nang le litaba tsa SiC tse tlohang ho 85% ho isa ho 99%, ho leka-lekanya ts'ebetso le litšenyehelo. Lehlaseli le leng le le leng le ikhethileng le feta litekong tse thata tsa boleng, ho kenyeletsoa ho otloloha (≤1‰) le liteko tsa matla a kobehang (ho fihlela ho 280MPa ho 1200℃), ho netefatsa ts'epo le polokeho. Re boetse re fana ka litharollo tse etselitsoeng liphutheloana le tsa thomello ea lefats'e ho netefatsa hore lihlahisoa tsa hau li fihla li sa senyeha ebile li le ka nako.
Jwalo ka moetsi wa dihlahiswa tsa SiC ya profeshenale, re kopanya theknoloji e tswetseng pele ya ho sinter le dilemo tsa boiphihlelo ba indasteri ho fana ka ditharollo tsa boleng bo hodimo tse ikgethileng. Mahlasedi a rona a sekwere a silicon carbide a ikgethileng ha a fihlelle feela ditlhoko tsa hao tsa tshebetso empa hape a thusa ho fokotsa tshebediso ya matla le ho ntlafatsa bokgoni ba tlhahiso. Hore na o hloka boholo bo tlwaelehileng, meralo e ikgethileng ka botlalo, kapa keletso ya botekgeniki e ikgethileng indastering ya hao, ikopanye le rona kajeno bakeng sa khotheishene ya mahala, e se nang tlamo le puisano ya profeshenale. E re mahlasedi a rona a sekwere a SiC a sebetsang hantle, a ikgethileng a matlafatse mesebetsi ya hao ya mocheso o phahameng—e eketsa botsitso, e fokotsa ditjeo, mme e phahamise bokgoni ba hao ba tlhahiso.
