Kwimimandla yanamhlanje efana nee-semiconductors, amandla amatsha, kunye ne-aerospace, izinto zeseramikhi ezingwevu-mnyama zidlala indima ebalulekileyo ngokuzolileyo.i-silicon carbide ceramic– into enobunzima obufana nobedayimani, etshintsha ubuso beshishini lanamhlanje ngenxa yokumelana kwayo nobushushu obuphezulu, ukumelana nokugqwala kunye nokuqhuba kwayo ubushushu obuphezulu. Kodwa kuncinci okwaziwayo ukuba ukuguqula umgubo we-silicon carbide oqinileyo ube zizixhobo ezichanekileyo, kufuneka inkqubo yomlingo "yokubumba ubushushu obuphezulu".
I. Inkqubo yokuHlamba: Umlingo oPhambili wokuguqula amatye abe yigolide
Ukuba umgubo we-silicon carbide uthelekiswa ne-jade engapholishwanga, inkqubo yokusila yeyona nkqubo iphambili yokuyibumba ibe yimveliso entle. Ngokusebenzisa ubushushu obuphezulu kwi-800-2000℃, amasuntswana omgubo anobukhulu be-micron aphinda "axhawule izandla" kwinqanaba le-athomu, enze umzimba we-ceramic oqinileyo noqinileyo. Iinkqubo ezahlukeneyo zokusila, njengeendlela ezahlukeneyo zokukrola, zinika izixhobo ezineempawu zokusebenza ezizodwa:
1. Ukutshisa koxinzelelo lomoya: Eyona ndlela yesiqhelo "yokupheka kancinci kubushushu obuphantsi"
Njengokuba isuphu emnandi ephekiweyo kancinci kufuneka iphekwe kubushushu obuphantsi, le nkqubo ivumela umgubo ukuba uqine ngokwendalo kumaqondo obushushu aphezulu ahlala ixesha elide. Nangona umjikelo umde, unokugcina "incasa yokuqala" yento kwaye ifanelekile ngakumbi kwizixhobo ze-semiconductor ezineemfuno ezingqongqo zobumsulwa.
2. Ukucofa ngobushushu: Indlela elawulwa ngokuchanekileyo "yokwenza ukubumba ngoxinzelelo oluphezulu"
Ukusebenzisa uxinzelelo loomatshini kwindawo enobushushu obuphezulu kufana nokunika "i-hot compress massage" echanekileyo kwisixhobo, enokususa ngokukhawuleza izithuba zangaphakathi. Iindawo zeseramikhi eziveliswa yile nkqubo zinobunzima obufana nexabiso lethiyori kwaye zilukhetho olufanelekileyo lokwenza iibheringi kunye nezitywini ezichanekileyo.
3. Ukusasaza I-Reaction: "Umlingo Weekhemikhali" kwiLizwe leZinto
Ngokusebenzisa ngobuchule indlela esebenza ngayo ikhemikhali phakathi kwe-silicon ne-carbon, izithuba zigcwaliswa ngokuzenzekelayo ngexesha lenkqubo yokusila. Olu phawu "lokuziphilisa" lwenza ukuba ibe sisixhobo esinamandla sokwenza iindawo ezintsonkothileyo nezingaqhelekanga, ezifanelekileyo kwiimveliso ezahlukeneyo ezimelana nobushushu obuphezulu, ezimelana nokugqwala, ezimelana nokugqwala okanye ezinye iindawo ezenzelwe wena.
Ii. Ukukhetha Inkqubo: Ubulumko Bokulungisa Izinto Ukuze Zilingane
Kanye njengokuba abathungi abaphezulu bekhetha izithungo ngokusekelwe kwiimpawu zelaphu, iinjineli kufuneka ziqwalasele ngokupheleleyo iimfuno zemveliso:
Xa usebenza ngezinto ezimile ngendlela engacwangciswanga ezinodonga olubhityileyo, "iteknoloji yokungena" yokusabela kwe-reaction sintering inokugcina imo egqibeleleyo
Iitreyi ze-semiconductor ezineemfuno ezingqongqo zeendawo ezithe tyaba kakhulu zinokuqinisekisa ukuba akukho tshintsho kwi-strain eqhelekileyo
Xa kusetyenzwa ngezinto ezinomthwalo ophezulu, uxinano oluphezulu kakhulu lwe-hot-pressing sintering ludla ngokukhethwa
Iii. Ubuchule bobuchwepheshe obungabonakaliyo
Kwimbali yokuvela kweteknoloji yokusila, izinto ezimbini ezintsha ezifihlakeleyo zibaluleke kakhulu: ukongezwa okuncinci kwe-AIDS yokusila kufana "neglue yemolekyuli", enciphisa ukusetyenziswa kwamandla ngelixa inyusa amandla; Inkqubo yolawulo lobushushu yedijithali iyafana "nompheki okrelekrele", igcina ukuguquguquka kobushushu ngaphakathi kwe-±5℃ kwaye iqinisekisa ukuhambelana kokusebenza kwebhetshi nganye yezinto.
Ukususela kwintsimi yemizi-mveliso engagugiyo nengagugiyo ukuya kushishino lwe-semiconductor oluphambili, ii-silicon carbide ceramics ziphinda zibumbe imeko yemizi-mveliso yanamhlanje. Utshintsho oluqhubekayo lwetekhnoloji yokusila lufana nokunika amaphiko le nto yomlingo, ivumela ukuba ibhabhe iye esibhakabhakeni esibanzi sesicelo. Njengomvelisi ochwephesha obandakanyeke kakhulu kwicandelo le-silicon carbide ceramics kangangeminyaka engaphezu kweshumi, uShandong Zhongpeng uyiqonda kakuhle incoko phakathi kwezinto kunye nolawulo lobushushu kunaye nabani na omnye. Ukulungiswa ngakunye kwe-sintering curve kukuphinda kuguqulwe unxantathu wegolide "wexesha lobushushu-uxinzelelo". Ukufiphaza komlilo wesithando kunye ne-oven kuyaqhubeka kubhala isahluko sokuvela kwee-ceramics zoshishino. Sithembele ekuthembekeni kophando oluzimeleyo kunye nophuhliso kunye neetekhnoloji ezininzi ezinelungelo lobunikazi, sisoloko sizimisele ukubonelela abathengi ngesisombululo esinye ukusuka ekucoceni izinto eziluhlaza ukuya ekusileni ngokuchanekileyo, siqinisekisa ukuba yonke imveliso ye-silicon carbide ceramic ithwala ubushushu beminyaka elishumi yobugcisa. Indlela engaphambili iyathomalaliswa, kwaye ngokwenziwa ngokuphindaphindiweyo, iba yinto entsha. Siyakumema ngokunyanisekileyo ukuba ujoyine nathi ekuboneni indlela le ntlantsi yobulumko kwii-ceramics zoshishino ekhanyisa ngayo izinto ezingenakwenzeka. Sisoloko sikholelwa ukuba yonke inkqubela phambili kwisayensi yezinto eziphathekayo iqokelela amandla ukuze uluntu ludlule kwimida yetekhnoloji.
