Ukususela kwiipayipi zothutho ukuya kwizithuthi ezintsha zamandla, ukusuka kwii-oven ezishushu kakhulu ukuya kwi-satellites zeenqwelo-moya, into eyaziwa ngokuba yi-"idayimani yemizi-mveliso" ibhala ngokutsha ngokuzolileyo imida yemveliso yanamhlanje.Iiseramikhi zeSilicon Carbide, into eqinileyo kakhulu enobunzima obungaphezulu kwedayimani yendalo, ibangela utshintsho olungabonakaliyo kwiinkalo ezahlukeneyo ezifana neshishini lanamhlanje, ii-semiconductors, i-aerospace, kunye namandla amatsha ngenxa yokumelana kwayo nobushushu obuphezulu, ukumelana okukhulu kwemitha, kunye nokuqhuba kakuhle kobushushu.
Xa 'amathambo aqinileyo' edibana nokuveliswa ngokuchanekileyo
Ukuba iiceramics zemveli ziyi-porcelain eluhlaza okwesibhakabhaka namhlophe kubugcisa kunye nemisebenzi yezandla, ngoko iiceramics ze-silicon carbide zifana kakhulu neewotshi zaseSwitzerland kwizixhobo ezichanekileyo. Ubunzima bayo buphindwe kathathu ukuya kahlanu kunobo be-ceramics eziqhelekileyo, kwaye obu bunzima bufana needayimani zendalo benza inkqubo yokugaya ifane nokusika kwiipleyiti zentsimbi - izixhobo zokusika eziqhelekileyo ziyaguga ngesantya esimangalisayo ngexesha lokusika. Okunzima nangakumbi kukuba uhlobo "olunzima" lwe-silicon carbide luyenza ithambekele ekuqhekekeni komphetho ngempazamo encinci ngexesha lokucutshungulwa, ngakumbi kwezinye iindawo ezinodonga oluncinci ezifuna unonophelo olufanayo nemisebenzi yobugcisa yekristale.
Kodwa imfuno yemizi-mveliso yanamhlanje ibangela uphuhliso kwezobuchwepheshe. Iinjineli zifumanise ukuba isitshixo sokusombulula le ngxaki sikwindibaniselwano yokuqina nokuguquguquka: ukugcina iimpawu zangaphakathi zezinto ngelixa kusetyenziswa ulawulo oluchanekileyo ngexesha lokucubungula. Njengabapheki abaphezulu abalawula ubushushu, iindlela zanamhlanje zokucubungula izinto zithomalalisa kancinci kancinci ezi zinto ziqinileyo ngokulawula ubushushu ngokuchanekileyo, uxinzelelo, kunye nokuphindaphinda kokungcangcazela.
Izitshixo ezintathu zokuvula iidayimani zemizi-mveliso
1. Ukubumba okucinezelweyo okushushu
Le yenye yezona ndlela zixhaphakileyo zokucubungula iiseramikhi ze-silicon carbide. Le ndlela ibeka umgubo we-silicon carbide okanye umgubo oxutyiweyo kwisikhunta esishushu esicinezelayo kwaye siyicubungule ibe yimo phantsi kobushushu obuphezulu kunye noxinzelelo. Isebenza kakuhle kakhulu kwimveliso kwaye ichanekileyo, kwaye ifanelekile ukuvelisa iimveliso zeseramikhi ze-silicon carbide ezinkulu ezifana nezixhobo zokusika, iipleyiti ze-aluminium ezitsalwa ngobushushu, njl.njl.
2. Ukubumba i-Grouting
Le yindlela yokwenza izinto engabizi kakhulu kwaye ikhawuleza kwiimveliso zeseramikhi zesilicon carbide. Le ndlela ixuba umgubo wesilicon carbide nezinye izongezo, iwafake emanzini ukuze enze i-slurry, ize iwufake kwi-mold mold. Emva koko, iyacutshungulwa kwaye yenziwe ngokumisa kunye nokusila ngobushushu obuphezulu, ngomjikelo omfutshane wokucubungula kunye nexabiso eliphantsi. Ifanelekile ukulungiselela iindawo ezinamandla aphezulu, ezinoxinano olukhulu kunye nezixhobo ezithwala umthwalo.
3. Isinyithi esenziwe ngomgubo
I-powder metallurgy yindlela yokuxuba nokubumba i-silicon carbide powder ngomlinganiselo othile, uze uyitshise kubushushu obuphezulu kunye noxinzelelo oluphezulu. Le ndlela inenkqubo elula yokuvelisa, iimilo ezahlukeneyo zemveliso, kunye nokuchaneka okuphezulu kokucubungula, okwenza ifaneleke ukuvelisa iimveliso zeseramikhi ezichanekileyo kakhulu, ezinamandla aphezulu, kunye nezingagugiyo.
Ukususela kwiisampulu zelebhu ukuya kwimveliso enkulu kumgca wemveliso, impumelelo ekucutshungulweni kweeseramikhi ze-silicon carbide iqinisekisa inyaniso: akukho nto ingenakucutshungulwa, kuphela yiteknoloji engekagqitywa. Ngokukhula kwezobuchwepheshe obutsha obufana nokucubungula nge-laser kunye nokusila nge-microwave, le nto yayikade inzima kakhulu iyavuselela kwiifektri ezikrelekrele, ifaka amandla aqinileyo kwi "mveliso ekrelekrele yaseTshayina".
Kwilwandlekazi elikhulu lokuhlola isithuba kunye ne-green wave yamandla acocekileyo, ii-silicon carbide ceramics zibhala intsomi yemizi-mveliso yale mihla ngobuhle bazo obukhethekileyo bezinto ezibonakalayo. Olu ngquzulwano phakathi kobulukhuni kunye nobukrelekrele lunokuba luphawu olungapheliyo loluntu olugqitha imida yetekhnoloji.
