Embonini yokuncibilikisa i-aluminium kanye nokukhipha igesi encibilikisiwe ku-aluminium,ama-rotor e-graphitecishe seziyimishini ejwayelekile. Izimboni eziningi ziyazi kahle ukuthi ngaphandle kwengubo yokulwa nokubola, i-rotor izosetshenziswa ngokushesha. Ngenxa yalokho, "izingubo zokulwa nokubola ezinokushisa okuphezulu" ezahlukahlukene ziye zagcwala imakethe. Kodwa-ke, uma kukhulunywa ngezindawo zokukhiqiza zangempela, kuphakama umbuzo ovamile: kungani ingubo, okufanele ivikele i-rotor ye-graphite, ivame ukuba yingxenye yokuqala yokwehluleka ngaphansi kwezimo zokushisa okuphezulu, zesikhathi eside, nezinzima? Ochwepheshe abaneminyaka eminingi yesipiliyoni embonini ye-semiconductor bavame ukubhekana nezinkinga ezinjalo. Ngakho-ke, ukukhetha nokusebenzisa i-rotor ye-graphite anti-oxidation coatings ngempumelelo, kubalulekile ukuthi uqale uqonde izindlela zokwehluleka kwezingubo bese uhlola ukuthi inkampani enekhono ngempela ekuphathweni kwendawo yezinto ezibonakalayo ingazihlukanisa kanjani ezindaweni ezibalulekile.
I. Kungani ama-rotor e-graphite engakwazi ukwenza ngaphandle kwengubo yokulwa ne-oxidation?
I-Graphite ngokwayo "inobungane" kakhulu ne-aluminium encibilikisiwe:
- Ubuningi obuphansi kanye nesisindo esincane, okunciphisa umthwalo wokudlulisela;
- Ukumelana okuhle nokushaqeka kokushisa, akuthambekeli ekuqhekekeni ngaphansi kokujikeleza okuphindaphindiwe kokushisa;
- Kulula ukucutshungulwa, okuvumela izakhiwo eziyinkimbinkimbi ze-rotor impeller ezenza kube lula ukuxuba uketshezi lwe-aluminium kanye nokuhlakazeka kwama-bubble.
Kodwa-ke, futhi inobuthakathaka obubulalayo: izohlala i-oxidized futhi idliwe ezindaweni ezishisa kakhulu ezigcwele umoya-mpilo.
Ezimweni ezijwayelekile zokuncibilikisa i-aluminium:
- Izinga lokushisa le-aluminium encibilikisiwe livame ukuba phakathi kuka-720–780°C, kanti ezinye izimo ziphakeme nakakhulu;
- Ingxenye ye-rotor ivezwa emoyeni wesithando, lapho umoya-mpilo kanye nemikhiqizo yokushisa kungenakugwenywa khona;
- I-rotor ijikeleza ngesivinini esikhulu, iveza njalo i-graphite entsha enokushisa okuphezulu emoyeni.
Ngaphandle kwesembozo esisebenzayo sokulwa nokubola, i-rotor izobonisa:
- Izingqimba ezingaphezulu “zishiswa” kancane kancane, ngokuncipha okubonakalayo kosayizi emavikini noma ngisho nasezinsukwini;
- Ubuso buba buqinile futhi bunezimbobo, okuholela ekuhlakazekeni kwama-bubble okungalingani kanye nokunciphisa ukusebenza kahle kokukhipha igesi;
- Impuphu e-oxidized kanye nemfucumfucu ziyawa, zibe yimithombo yokufakwa ku-aluminium encibilikisiwe.
Umsebenzi wengubo yokulwa ne-oxidation ukusiza i-graphite ukuthi imelane nale "mpi yokusetshenziswa okungapheli" ngaphansi kwezimo ze-aluminium kanye ne-slag ezishisa kakhulu, ezicebile nge-oxygen, nezincibilikisiwe.
II. Kungani Ukumbozwa Kuqala Ngokuhluleka Ngaphansi Kwezimo Ezibucayi?
Ekuhlaziyweni kokwehluleka okuvamile, izimo ezivame ukuhlangana nazo zingahlukaniswa zibe yizimo eziningana ezijwayelekile:
1. Ukungafani Kokukhula Kokushisa: Ukwembozwa Okuhle “Kuyazidabula”
- Ukuziphatha kokukhula kokushisa kwezinto zokumboza ze-graphite kanye ne-inorganic kuhluke kakhulu:
- I-Graphite i-anisotropic kakhulu, inokwanda okuhlukile ngezindlela ezahlukene;
- Izembozo eziningi ze-ceramic noma zengilazi zine-coefficients yokukhulisa ukushisa ephezulu futhi "ziqinile" kakhulu.
Ngesikhathi sokujikeleza okuphindaphindiwe kokushisa, ukucwilisa, ukuvala, nokupholisa, izinto ezimbili azikhuli futhi azifinyeleli ngesikhathi esifanayo:
- Ama-microcrack aqala ukuvela embozweni;
- Lezi zimfa ziyaqhubeka nokusabalala ngaphansi kokujikeleza kwe-rotor kanye nokuhlafunwa kwe-aluminium encibilikisiwe;
- Ekugcineni, izindawo ezinkulu zokwemboza ziyaphuma, ziveze i-graphite substrate endaweni.
Uma ubheka phezulu kubukeka “njengekhwalithi yokumboza ephansi,” kodwa empeleni, ukuhambisana kokushisa ne-graphite akuzange kubhekwe njengomkhawulo oqinile wokuklama esigabeni sokwakheka kanye nokuklama kwesakhiwo.

- I-oksijini ingena ngemibhobho bese iqala ukuxova i-graphite ngaphansi kwengubo;
- Ingqimba engaphansi kwengubo ikhishwa kancane kancane, yakha “ama-blister” noma izikhala;
- Ngolunye usuku, phakathi nokukhiqiza, ingxenye yonke yokugqoka iyaqhekeka ngokuzumayo.
Okuvame ukubonwa endaweni ukuthi kokubili uhlangothi olungemuva lwengubo ewile kanye nobuso be-graphite obuveziwe sekuvele kukhululekile futhi kuyimpuphu.
3. Ukunganaki Ukugqwala Kwamakhemikhali Okuvela Ku-Aluminium Encibilikisiwe Ne-Slag
Izimo zesevisi ezimbi kakhulu azigcini nje ngokuba nokushisa okuphezulu. Zihlanganisa:
- Izinhlelo ze-aluminium alloy eziyinkimbinkimbi ezine-Mg ephezulu, i-Si ephezulu, noma izengezo zomhlaba ezingavamile;
- Izinsalela zezinto zokuhlanza nezokuvala ezisekelwe ku-chloride kanye ne-fluoride;
- I-slag enamathela ebusweni be-rotor isikhathi eside.
Uma ifomula yokumboza igxile kuphela ekubeni "imelana nokushisa okuphezulu" ngenkathi inganaki lezi zinto zamakhemikhali, izinkinga ezilandelayo zingase zenzeke:
- Izingxenye ezithile zokumboza endaweni zisabela nge-aluminium encibilikisiwe noma i-slag, zakha izigaba zokuncibilika okuphansi;
- Uma ithintana isikhathi eside, uqweqwe luyathamba kancane kancane futhi luguguleke ngamakhemikhali, kanti ubuso “budliwa” kancane kancane;
- Ubuso bokumboza buba buqinile, insimu yokugeleza iyawohloka, futhi ukusebenza kahle kokukhipha igesi kuyehla.
Ukuhlolwa kwezinga lokushisa eliphakeme lesikhathi esifushane elabhorethri akukwazi ukuphinda imiphumela eqongelelekayo yalolu hlobo lokuhlaselwa kwamakhemikhali kwesikhathi eside.
