Lefapheng la tlhahiso ea indasteri, ho khetha lisebelisoa tse loketseng tsa ceramic ho tšoana le ho fumana balekane ba tšepahalang - e hloka ho mamella teko ea nako, ho mamella maemo a feteletseng, le ho tsoela pele ho eketsa boleng ho katleho ea tlhahiso. U ka etsa khetho e bohlale joang ha u tobane le mefuta e mengata e makatsang ea lihlahisoa tsa ceramic tsa indasteri? Sengoliloeng sena se tla senola lintlha tsa bohlokoa tsa khetho ea lisebelisoa tsa setsebi le ho tsepamisa maikutlo ho hlahlobisiseng melemo e ikhethang eali-ceramics tsa silicon carbide, e tsejoang ka lebitso la "lihlomo tsa indasteri".
1, Melao e meraro ea Khauta ea ho Khetha li-Ceramics tsa Indasteri
1. Tekanyo ea ho bapisa ts'ebetso: Taba ea pele, hoa hlokahala ho hlakisa litlhoko tsa mantlha tsa boemo ba ts'ebeliso. Na ke tikoloho ea mocheso o phahameng haholo? Mokhoa o matla oa ho senya? Kapa likhohlano tsa mochini tse phahameng-frequency? Joalo ka ho khetha lisebelisoa tsa ho hloa lithaba ho khetholla pakeng tsa lehloa le lehoatata, maemo a fapaneng a ts'ebetso a hloka lisebelisoa tsa ceramic tse nang le litšobotsi tse tšoanang.
2. Potoloho ea bophelo ba tšebeletso: Bohlokoa ba li-ceramics tsa boleng bo phahameng bo bontšoa ka tšebeliso ea nako e telele. Ha rea lokela ho ela hloko feela litšenyehelo tsa pele tsa ho reka, empa hape re bale litšenyehelo tse hlakileng tse bakoang ke tlhokomelo le makhetlo a mangata. Li-ceramics tsa boleng bo holimo tsa indasteri li lokela ho ts'epahala joalo ka "likarolo tsa mahala tsa tlhokomelo".
3. Bokhoni ba ts'ehetso ea tekheniki: Bafani ba thepa e babatsehang ba ke ke ba fana ka lihlahisoa tse tloaelehileng feela, empa hape ba ntlafatsa liforomo le mehaho ea moralo ho latela maemo a itseng a sebetsang, ao hangata a khethollang ts'ebetso ea ho qetela ea lisebelisoa ka mekhoa e sebetsang.
2. Melemo e mene e meholo ea ts'ebetso ea silicon carbide ceramics
Joaloka lisebelisoa tsa linaleli tsa lirafshoa tsa morao-rao tsa indasteri, li-ceramics tsa silicon carbide li fetoha khetho e ratoang bakeng sa likhoebo tse ngata le ho feta. Motsoako oa eona o ikhethang oa ts'ebetso o ka bitsoa "mohlabani oa hexagonal" oa thepa ea indasteri:
1. Lihlomo tse tšoarellang haholo: Sebopeho sa kristale se e fa boima ba bobeli feela ho daemane, e ka khonang ho lelefatsa bophelo ba ts'ebeletso ea lisebelisoa maemong a joalo ka litsamaiso tsa phetisetso tse hatelletsoeng le li-bearings tse nepahetseng.
2. Thebe e sireletsang lik'hemik'hale: E na le khanyetso e babatsehang ea li-acids tse matla, tšepe e qhibilihisitsoeng, joalo-joalo, 'me e loketse ka ho khetheha bakeng sa libaka tse senyang tse kang likepe tsa lik'hemik'hale le mekhoa ea indasteri ea desulfurization, ho qoba tšilafalo e bohareng e bakoang ke tahlehelo ea thepa.
3. Thermal Stability Guardian: E ka boloka botsitso ba sebopeho esita le mocheso o phahameng oa 1350 ℃, e nang le coefficient ea ho atolosa mocheso feela 1/4 ea tšepe, e leng se etsang hore e be khetho e nepahetseng bakeng sa li-kilns tse phahameng tsa mocheso le li-spacecraft tsamaiso ea tšireletso ea mocheso.
4. Setsebi se bobebe: Ka boima ba karolo ea boraro feela ea tšepe, e ka fana ka matla a tšoanang kapa a phahameng a mochine, 'me e na le melemo e totobetseng ea thepa ea mochine le masimo a macha a matla a hlokang ho fokotsa boima ba' mele le ho ntlafatsa katleho.
3, Litlhahiso tsa khetho e tsoetseng pele ea thepa
Ho phaella ho li-parameter tsa motheo, ho kgothaletswa ho tsepamisa maikutlo ho lintlha tsa ts'ebetso tse kang ho lumellana ha microstructure le ho boreleli holimo. 'Litšobotsi tsena tse sa bonahaleng' hangata li laola ts'ebetso ea lisebelisoa maemong a mahlonoko.
Ho khetha li-ceramics tsa indasteri ha e le hantle ke ho khetha "mohlokomeli" oa mohala oa tlhahiso. Li-ceramics tsa silicon carbide, ka motsoako oa tsona o ikhethang oa thepa, li hlalosa bocha kutloisiso ea ho tšepahala tlhahisong ea indasteri. Ha u tobane le mathata a thata a ho sebetsa, tlohella sebapali sena se tenyetsehang indastering ea thepa ho u etsetsa mohala o matla oa ts'ireletso.
Re 'nile ra ameha ka botebo tšimong ea lirafshoa tsa silicon carbide ka lilemo tse fetang leshome, re tsepamisitse maikutlo ho faneng ka litharollo tsa thepa e hlophisitsoeng bakeng sa bareki. EtelaShandong Zhongpengho fumana lintlha tse lekantsoeng haholoanyane mabapi le maemo a kopo, kapa ikopanye le sehlopha sa rona sa boenjiniere ho u etsetsa tharollo ea khetho ea thepa.
