Ukufudumeza linyathelo elibalulekileyo kodwa elibalulekileyo kwiinkalo ezininzi zemveliso yemizi-mveliso. Ukusuka ekunyangweni kobushushu besinyithi ukuya ekutshiseni i-ceramic, kwanokusetyenzwa kwezixhobo ezithile ezikhethekileyo, kufuneka izixhobo zokufudumeza ezizinzileyo, ezisebenzayo neziguquguqukayo. Kule meko ineemfuno ezingqongqo zobushushu kunye nokuqina,imitha ye-silicon carbideIityhubhu ziba lukhetho lwamashishini amaninzi ngenxa yeenzuzo zazo ezikhethekileyo.
Abanye abantu banokuba nomdla wokuba, yintoni ityhubhu yemitha ye-silicon carbide? Ngamafutshane, sisithako sokufudumeza esinetyhubhu esenziwe kakhulu ngeeseramikhi ze-silicon carbide, esidla ngokusetyenziswa kunye neengcingo zokufudumeza, iintonga zokufudumeza kunye nezinye ii-cores zangaphakathi, kwaye sidlala indima "yokutshintsha ubushushu" kwii-oven zoshishino nakwezinye izixhobo. Nangona kunjalo, ukwahluka kwayo kukuba ayivelisi ngokuthe ngqo ubushushu obuphezulu, kodwa endaweni yoko idlulisela ubushushu ngokulinganayo kwindawo yokusebenza ekufuneka ifudunyezwe ngohlobo lwemitha ngokusebenzisa izinto zokufudumeza zangaphakathi ezijikelezileyo, ngelixa ikwakhusela izinto zangaphakathi kwimo engqongileyo eyinkimbinkimbi ngaphakathi kwi-oven.
Xa kufikwa kwiingenelo zeetyhubhu zemisebe ye-silicon carbide, "ukuxhathisa ubushushu obuphezulu" ngokuqinisekileyo yileyibhile yayo ephambili. Iityhubhu zokufudumeza zesinyithi eziqhelekileyo zinokuba nokuguquguquka kunye nokuxinana kumaqondo obushushu angamakhulu aliqela e-Celsius, ngelixa ii-silicon carbide ceramics ngokwazo zinokuxhathisa ubushushu obuphezulu kakhulu. Kwanakwii-ovens ezinobushushu obuphezulu ezingaphezulu kwe-1300 ℃, zinokugcina uzinzo lwesakhiwo kwaye azonakaliswa lula. Olu phawu luyivumela ukuba ivumelane neemeko ezininzi zokucubungula ubushushu obuphezulu, njengobushushu bokutsha kwezinye ii-ceramics ezikhethekileyo ezidla ngokudlula i-1200 ℃, kwaye iityhubhu zemisebe ye-silicon carbide zinokusebenza ngokuthembekileyo kwiindawo ezinjalo ixesha elide.
Ukongeza ekumelaneni nobushushu obuphezulu, "ukuxhathisa ukugqwala" nako kuphawu oluphambili. Kwiinkqubo ezininzi zokufudumeza kwimizi-mveliso, kunokubakho iigesi ze-asidi, ze-alkaline okanye ezinye izinto ezigqwalisayo kwi-oven, ezinokugqwala ngokulula izinto zokufudumeza kwaye zinciphise ubomi benkonzo yesixhobo. Uzinzo lweekhemikhali zezinto ze-silicon carbide luqinile, kwaye akulula ukusabela ngezi zinto zigqwalisayo, oko kuthetha ukuba zinokugcina ukuqina okuhle kwiindawo ezixineneyo ze-oven, zinciphise ukuphindaphinda kokutshintshwa kwezixhobo, kwaye ekuhambeni kwexesha, zinciphise neendleko zemveliso kunye nokugcinwa kwamashishini.
Ukongeza, "ukusebenza kakuhle kobushushu" kweetyhubhu zemitha ye-silicon carbide kufanelekile ukukhankanywa. Ukuqhuba kwayo ubushushu kulungile, okunokudlulisa ngokukhawuleza ubushushu obuveliswa zizinto zokufudumeza zangaphakathi kwaye kufudumeze umsebenzi ngemitha. Le ndlela yokufudumeza ayitshisi nje ngokukhawuleza, kodwa ikwayenza ukuba ubushushu bube bufana ngakumbi, kuthintelwe ubushushu obuphezulu okanye ubushushu obungonelanga. Oku kubaluleke kakhulu ukuqinisekisa ukuhambelana komgangatho wokucubungula imveliso. Umzekelo, kunyango lobushushu lweendawo zesinyithi, ukufana kobushushu kuchaphazela ngokuthe ngqo ubulukhuni, ukuqina, kunye nezinye iimpawu zeendawo, kwaye iityhubhu zemitha ye-silicon carbide zinokubonelela ngenkxaso ezinzileyo kule nkalo.
Kakade ke, ukusetyenziswa kweetyhubhu zemisebe ye-silicon carbide akunamida. Umzekelo, iindleko zazo ziphezulu kakhulu kunezo zeetyhubhu zokufudumeza zesinyithi eziqhelekileyo, kwaye ngenxa yeempawu zezinto ze-ceramic, kufuneka ziphephe ukungqubana okukhulu ngexesha lokufakwa nokusetyenziswa ukuthintela umonakalo. Kodwa kumashishini aneemfuno eziphezulu zobushushu bokufudumeza, ukubola kokusingqongileyo, kunye nomgangatho wemveliso, uzinzo, ukusebenza kakuhle, kunye nobomi obude ezizisayo zihlala zilungisa ezi ngxaki zincinci.
Kule mihla, ngophuhliso lwemveliso yemizi-mveliso oluya ngokuchanekileyo ngakumbi nakwizinga eliphezulu, iimfuno zezixhobo zokufudumeza nazo ziyanda rhoqo. Njengento egqwesileyo yokufudumeza yemizi-mveliso, iityhubhu zemitha ye-silicon carbide zidlala indima enkulu kancinci kancinci kwiinkalo ezifana ne-ceramics, i-metallurgy, kunye ne-elektroniki. Isenokungabi yinto ekhangayo njengezinye iiteknoloji ezintsha, kodwa yile mpawu "yokunamathela kwisikhundla sayo" buthule kwiindawo ezigqithisileyo ezenza ukuba ibe "yingcali echasene nobushushu obuphezulu" ebalulekileyo kwimveliso yemizi-mveliso, inika iziqinisekiso ezinokuthenjwa kwiinkqubo ezahlukeneyo zokufudumeza ezifunekayo kakhulu.
