Na o batla thepa ea ka tlung e tsitsitseng haholo e ka mamellang sepakapaka se senyang le ho potoloha mocheso o phahameng khafetsa?Lipoleiti tsa Silicon Carbide (OBSiC) tse kopantsoeng le Oxideke tharollo ea boleng bo holimo bakeng sa lits'ebetso tsa ho besa le ho sila mocheso o phahameng oa indasteri. Li ntlafalitsoe ka theknoloji ea bond ea oxide ea profeshenale, lipoleiti tsena tsa SiC li fana ka botsitso bo phahameng ba lik'hemik'hale le ho tiea ha sebopeho, li sebetsa hantle ho feta lipoleiti tsa ceramic tse tloaelehileng bakeng sa libaka tse thata tsa ontong ea indasteri.
Ho fapana le dihlahiswa tsa SiC tse boeleditsweng, dipoleiti tsa rona tsa SiC tse bopetsweng ka oxide di amohela bokgoni bo tswetseng pele ba ho sinter le ho kopanya oxide. Sebopeho sa bopello ba oxide e tiileng se ntlafatsa haholo boima ba sehlahiswa le botsitso ba sebopeho, se tlisa melemo e mmedi ya bohlokwa:khanyetso e ntle ea ho oxidation ea mocheso o phahamengleho hanyetsa ho ts'enyeha ho feteletsengLipoleiti li ka sebetsa ka botsitso mochesong oa nako e telele oa1350°C ho isa ho 1400°C, ntle le ho fetoha, ho petsoha kapa tshenyo ya sebopeho nakong ya tlhahiso ya potoloho e telele.
E hanyetsa ka mokhoa o ikhethang ho ts'oaroa ke mocheso le coefficient e tlase ea katoloso ea mocheso. E mamella potoloho ea ho futhumatsa le ho pholisa khafetsa ntle le ho petsoha kapa ho robeha, e rarolla mathata a tloaelehileng a tšenyo ea lipoleiti tsa ontong tsa alumina tsa setso ka katleho.
Ho tsamaisa mocheso ka tsela e tšoanang le e potlakileng ho netefatsa kabo e lekanang ea mocheso ka har'a ontong, ho felisa ho chesa haholo sebakeng seo le boleng bo sa tsitsang ba ho besa, e leng se ntlafatsang haholo chai ea sehlahisoa se felileng.
E hanyetsa likhase tse senyang, mosi oa alkaline le lerōle la flue le mocheso o phahameng. E ke ke ea nkeloa sebaka maemong a tlhahiso a boima ao lipoleiti tse tloaelehileng tsa SiC li ke keng tsa ikamahanya le 'ona.
Tšobotsi e hlahelletseng ka ho fetisisa ea lipoleiti tsa silicon carbide tse kopantsoeng le oxide ke ho hanyetsa ha tsona ka matla likhase tse senyang, mosi oa alkaline le lerōle la flue le mocheso o phahameng. Li sebelisoa haholo e lelishelefo tsa ontong, lipoleiti tsa ho sintering, masela a ontong le lipoleiti tsa ho jarabakeng sa:
Lihlahisoa tse sebelisoang letsatsi le letsatsi tsa letsopa
Meaho ea Liseramike
Liserami tsa Meaho
Tšepe ea phofo
Ho Sintering ea Lintho tsa Lik'hemik'hale
Tlhahisong ea 'nete ea indasteri, lipoleiti tsa rona tsa OBSiC li na le tšobotsibophelo bo bolelele ba tšebeletso, ho se kgohle ha bonolo le ho hloka tshilafatso. Li ke ke tsa hlahisa phofo e oang kapa pula e sa hloekang nakong ea ts'ebetso ea mocheso o phahameng, e leng se sireletsang bohloeki le boleng ba bokaholimo ba lihlahisoa tse sintered ka katleho.
Maqhubu a tlhokomelo a tlase
Tšebeliso e ntle haholo
Litšenyehelo tse fokotsehileng tsa ho nkela thepa ea ka tlung sebaka
Nako e fokotsehileng ea tlhahiso
Re fana ka boholo bo ikhethileng, botenya le ts'ebetso e bōpehileng ho latela liparamente tsa onto ea bareki le litlhoko tsa tlhahiso. Lihlahisoa tsohle li hlahlojoa ka thata ho netefatsa ts'ebetso e tsitsitseng ea sehlopha.
Khetha lipoleiti tsa rona tsa carbide tsa silicon tse kopantsoeng le oxide ho ntlafatsa ts'ebetso ea hau ea ho thunya le ho fihlella katleho e phahameng ea tlhahiso le litšenyehelo tse tlase tsa ts'ebetso.Ikopanye le rona bakeng sa disampole tsa mahala le litheolelo tsa boholo ba fektheri!
