Emikhakheni esezingeni eliphezulu njengemishini yokudlulisa amandla, amandla amasha, kanye nezindiza, izinto zobumba ezimpunga-mnyama zidlala indima ebalulekile buthule.i-silicon carbide ceramic– into enobulukhuni obufana nobedayimane, eshintsha ubuso bemboni yanamuhla ngenxa yokumelana kwayo nokushisa okuphezulu, ukumelana nokugqwala kanye nokushisa okuphezulu. Kodwa akwaziwa kangako ukuthi ukuguqula i-hard silicon carbide powder ibe amadivayisi anembile, inqubo yomlingo "yokwakha ukushisa okuphezulu" iyadingeka.
I. Inqubo Yokucwenga: Umlingo Oyisihluthulelo Wokuguqula Amatshe Abe Igolide
Uma i-silicon carbide powder iqhathaniswa ne-jade engapholishiwe, inqubo yokusila iyinqubo eyinhloko yokuyibumba ibe umkhiqizo omuhle. Ngokufaka ukushisa okuphezulu ku-800-2000℃, izinhlayiya ze-powder ezinobukhulu be-micron ziphinde "zixhawulane" ezingeni le-athomu, zakha umzimba we-ceramic oqinile noqinile. Izinqubo ezahlukene zokusila, njengezindlela ezahlukene zokuqopha, zinikeza izinto ezinezici zokusebenza ezihlukile:
1. Ukushisa kwengcindezi yomoya: Indlela evamile kakhulu "yokupheka kancane kancane ekushiseni okuphansi"
Njengoba nje isobho elimnandi eliphekwe kancane lidinga ukubiliswa ekushiseni okuphansi, le nqubo ivumela impuphu ukuthi iqine ngokwemvelo emazingeni okushisa aphezulu isikhathi eside. Nakuba umjikelezo umude kakhulu, ungagcina "ukunambitheka kwasekuqaleni" kwezinto futhi ufaneleka kakhulu ezingxenyeni zemishini ye-semiconductor enezidingo eziqinile zokuhlanzeka.
2. Ukucindezela ngokushisa: "Indlela yokwakha enomfutho ophezulu" elawulwa ngokunembile
Ukusebenzisa ingcindezi yomshini endaweni eshisa kakhulu kufana nokunikeza "ukubhucungwa okushisayo" okuqondile entweni, okungasusa ngokushesha izikhala zangaphakathi. Izingxenye ze-ceramic ezikhiqizwa yile nqubo zinobukhulu obufana nenani elicatshangelwe futhi ziyisinqumo esifanele sokwenza amabheringi nama-seal anembile.
3. Ukusabela Okungajwayelekile: “Umlingo Wamakhemikhali” Emhlabeni Wezinto Ezibonakalayo
Ngokusebenzisa ngobuhlakani ukusabela kwamakhemikhali phakathi kwe-silicon ne-carbon, izikhala zigcwaliswa ngokuzenzakalelayo ngesikhathi senqubo yokusila. Lesi sici "sokuziphilisa" senza kube ithuluzi elinamandla lokukhiqiza izingxenye eziyinkimbinkimbi nezingavamile, ezifanele imikhiqizo ehlukahlukene engamelani nokushisa okuphezulu, engagugi, engagqwali noma ezinye izingxenye ezenziwe ngokwezifiso.
Ii. Ukukhetha Inqubo: Ukuhlakanipha Kokulungisa Izinto Ukuze Zilingane
Njengoba nje abathungi abaphezulu bekhetha izithungo ngokusekelwe ezicini zendwangu, onjiniyela kudingeka bacabangele ngokugcwele izidingo zomkhiqizo:
Uma usebenzisana nezingxenye ezincane ezimise okwezingajwayelekile, "ubuchwepheshe bokungena" bokuthungula ukusabela bungagcina isimo esiphelele
Amathreyi e-semiconductor anezidingo eziqinile zezindawo ezisicaba kakhulu angaqinisekisa ukuthi akukho ukuguquguquka ngenxa yokushisa kwengcindezi okuvamile
Uma kukhulunywa ngezingxenye ezinomthwalo omkhulu, ubuningi obukhulu kakhulu bokucindezela okushisa buvame ukukhethwa
Iii. Ukuphumelela Kwezobuchwepheshe Okungabonakali
Emlandweni wokuziphendukela kwemvelo kobuchwepheshe bokuthungula, izinto ezimbili ezintsha ezifihliwe zibaluleke kakhulu: ukwengezwa okuncane kwe-AIDS yokuthungula kufana "neglue yama-molecule", okunciphisa ukusetshenziswa kwamandla ngenkathi kuthuthukiswa amandla; Uhlelo lokulawula izinga lokushisa lwedijithali lufana "nompheki ohlakaniphile", olugcina ukushintshashintsha kwezinga lokushisa kungaphakathi kuka-±5℃ futhi luqinisekisa ukuhambisana kokusebenza kweqoqo ngalinye lezinto.
Kusukela ensimini yezimboni engagugi futhi engagqwali kuya embonini ye-semiconductor ethuthukisiwe, i-silicon carbide ceramics ishintsha isimo semboni yesimanje. Ukusungula izinto ezintsha okuqhubekayo kobuchwepheshe bokushwiba kufana nokunikeza amaphiko kule nto yomlingo, okwenza ikwazi ukundiza esibhakabhakeni esibanzi. Njengomkhiqizi ochwepheshe ohileleke kakhulu emkhakheni we-silicon carbide ceramics iminyaka engaphezu kweshumi, uShandong Zhongpeng uyaqonda ingxoxo phakathi kwezinto zokwakha nokulawula ukushisa kangcono kunanoma ubani omunye. Ukulungiswa ngakunye kwe-sintering curve kuwukubhidlizwa kabusha kwe-golden triangle "yesikhathi sokushisa-ingcindezi". Ukufiphaza komlilo wesithando ngasinye nomlilo wesitofu kuyaqhubeka nokubhala isahluko sokuziphendukela kwemvelo se-ceramics zezimboni. Sithembele ekuthembekeni kocwaningo oluzimele kanye nentuthuko kanye nobuchwepheshe obuningi obunelungelo lobunikazi, sihlala sizibophezele ekuhlinzekeni amakhasimende ngesisombululo esisodwa kusukela ekuhlanzweni kwezinto zokusetshenziswa kuya ekushwibeni okunembile, siqinisekise ukuthi yonke imikhiqizo ye-silicon carbide ceramic ithwala ukufudumala kweminyaka eyishumi yobuciko. Indlela engaphambili iyaqiniswa, futhi ngokwakhiwa okuphindaphindiwe, iba yintsha. Sikumema ngobuqotho ukuthi uhlanganyele nathi ekuboneni ukuthi le nhlansi yokuhlakanipha ku-ceramics zezimboni ikhanyisa kanjani izinto ezingenakwenzeka. Sihlala sikholelwa ukuthi yonke intuthuko kwezesayensi yezinto ezibonakalayo iqoqa amandla ukuze isintu sidlule emikhawulweni yezobuchwepheshe.
