Kwenziwa kanjani ama-cebito carbiide ceramics

I-Alicon Carbide (Sic) ceramicsbaziwa ngamandla abo amangalisayo, ukumelana nokushisa, nokuqina. Lezi zakhiwo zizenza zilungele ukusetshenziswa ezindaweni ezinzima, njengezinjini ze-aerospace noma imishini yezimboni. Kepha zidalwe kanjani ngempela lezi zinto ezithuthukisiwe? Ake sihlukanise inqubo ngesinyathelo ngesinyathelo.

Ukulungiswa Kwezinto Ezibonakalayo

Konke kuqala nge-Silicon Carbide Powder ephezulu. Cabanga ngalokhu ngokuthi "ufulawa" wokubhaka "ikhekhe lemibhalo.

2. Ukubumba i-ceramic

I-powder iphendulwa ibe yifomu elibumbayo. Kusetshenziswa izindlela ezimbili ezijwayelekile:

Ukucindezela: I-powder icindezelwe esimweni esithile kusetshenziswa ingcindezi ephezulu, efana neqhwa elihlanganayo libe yi-snowball.

Ukubumba komjovo: I-powder ixubene ne-binder yesikhashana (njenge-wax) ukudala ingxube efana nenhlama, efakwe ekubumbeni amajamo ayinkimbinkimbi.

Kulesi sigaba, okuqukethwe kusantekenteke okufana nesihlabathi esomile - futhi kudingeka 'kubhakwe' ukuze siqine.

3. Inqubo yesono

Yilapho umlingo wenzeka khona. I-ceramic ebunjiwe ifudunyezwa esithandweni esikhethekile kumazinga okushisa aphezulu kakhulu (kaningi ngaphezulu kwe-1,800 ° C). Ngesikhathi sokuthola isono, kwenzeka izinto ezimbili ezibalulekile:

Izinhlayiyana ze-Particle

Umsebenzi we-Addtitives: Amakhompiyutha angeziwe ancibilika kancane, adale "ibhuloho" phakathi kwezinhlayiya ukuze athuthukise ubunzima.

Imvelo engaphakathi esithandweni somlilo ilawulwa ngokucophelela - kwesinye isikhathi igcwele amagesi we-inert-ukuvikela ukusabela okungafuneki.

4. Ukuqeda Ukuthinta

Ngemuva kokusona, ubumbano bungahle bube nokwelashwa okwengeziwe kokucwilisa ukusebenza kwalo:

I-Polishing: Ngezicelo ezidinga indawo ebushelelezi (isib., Izimpawu noma izimpawu).

I-Coating: ungqimba oluncane oluvikelayo (njenge-silicon nitride) lungezwa ukukhulisa ukumelana kokugqoka.

Imishini: Ukusika okunembile noma ukumba ukufeza ubukhulu bokugcina.

Kungani le nqubo ibalulekile

Imfihlo yamandla ka-Silicon Carbide alele ekutheni ama-athomu awo abopha kanjani lapho esona khona. Inqubo yokushisa ephezulu idala inethiwekhi yama-silicon-carbon bond, amelana nokushisa, ukugqwala kanye nokuxineka ngokomzimba. Izengezo kanye nokulawulwa kokushisa okuqondile kuqinisekisa umkhiqizo wokugcina akunzima nje kodwa futhi kunzima ngokwanele ukumelana nokuqhekeka.

Isithombe esikhulu

Kusuka kuma-turbines wokusika-onqenqemeni azolawula ukungcola, ama-ailcon carbiide ceramics adlala indima ebalulekile kubuchwepheshe besimanje. Ngenkathi inqubo yokukhiqiza iyinkimbinkimbi, lokhu kulinganisela ngokucophelela kwesayensi nobunjiniyela obuguqula i-powder elula ibe ngokwakha okubonakalayo okunezinhloso ezinzima kakhulu.

Njengenqubekela phambili yocwaningo, izindlela ezintsha - njengokuphrinta kwe-3D kwama-ceramics - kuyavela, kuthembisa ukusetshenziswa okusha kwalesi sicelo esingajwayelekile.
