Kwinkalo yokusetyenziswa kobushushu obuphezulu kushishino lwanamhlanje, izinto zokufudumeza zombane ze-silicon carbide zivela ngokukhawuleza njengetekhnoloji ebalulekileyo eyimfuneko kumashishini amaninzi. Njengezixhobo zokufudumeza zombane ezingeyiyo eyentsimbi, iintonga ze-silicon carbide ziguqula ngokunzulu imbonakalo yomhlaba yamashishini anobushushu obuphezulu kunye neempawu zabo ezimangalisayo zokumelana nobushushu obuphezulu, ukuxhathisa kwe-oxidation, kunye nokuxhathisa ukubola.
Umgaqo wokusebenza we-silicon carbide rods usekwe kwizinto ezizodwa zombane kunye ne-thermal ye-silicon carbide materials. Xa umsinga wombane udlula kwintonga ye-silicon carbide, ukuhamba kwee-electron ngaphakathi kwe-silicon carbide kuvelisa ubushushu obuxhathisayo, okwenza uguquko olusebenzayo lwamandla ombane lube ngamandla obushushu. Le nkqubo yokuguqula ayisebenzi kakuhle kuphela kodwa ikwazinzile, ivumela iirodi ukuba zisebenze ngokuqhubekayo kumaqondo obushushu afikelela kwi-1500°C okanye nangaphezulu, ibonelela ngomthombo wobushushu othembekileyo kwiinkqubo ezahlukeneyo zobushushu obuphezulu.
Ngokubhekiselele kwizicelo, izinto zokufudumeza zombane ze-silicon carbide zamkelwe ngokubanzi kuwo onke amashishini amaninzi. Kwintsimi ye-metallurgical, ii-silicone ze-carbide ezixineneyo eziphezulu zisebenza njengezona zinto ziphambili zokufudumeza kwiziko lombane, zibonelela ngendawo ezinzileyo yobushushu obuphezulu bokunyityilikiswa kwesinyithi njengentsimbi kunye nobhedu. Okwangoku, banokuxhathisa ngokufanelekileyo ukukhukuliseka kwe-atmospheres eyinkimbinkimbi ngaphakathi kwesithando somlilo, ukwandisa kakhulu ubomi benkonzo yezixhobo. Kwimizi-mveliso ye-ceramic kunye neglasi, i-thermal conductivity egqwesileyo ye-silicon carbide rods iqinisekisa ukufudumeza okufanayo ngexesha le-sintering kunye neenkqubo zokunyibilika kweemveliso, ngaloo ndlela ziphucula umgangatho wemveliso kunye nesivuno. Ukongeza, kwiinkalo ezifana nokusetyenzwa kwezinto ze-semiconductor, ukuveliswa kwezinto ze-elektroniki, kunye novavanyo lophando lwezenzululwazi, iintonga ze-silicon carbide zithandwa kakhulu ngenxa yeenzuzo zazo ezifana nokufudumeza ngokukhawuleza kunye nokulawula ubushushu obuchanekileyo.
Ngokuqhubela phambili kweenjongo "zekhabhoni ezimbini", izibonelelo zokonga amandla kwi-silicon carbide intonga yokufudumeza kombane ziye zavela ngakumbi. Ukufudumeza kwabo ngokukhawuleza kunciphisa ukusetyenziswa kwamandla, ngelixa isiphumo sokufudumeza esifanayo sikhuthaza ukuphendula ngokucokisekileyo, ukunciphisa ukusetyenziswa kwamandla okwesibini. Ngaphezu koko, ubomi benkonzo ende yeentonga ze-silicon carbide kunciphisa ukuveliswa kwezinto ezilahliweyo, ukubonelela ngenkxaso eqinile kuphuhliso oluzinzileyo lwemveliso yemizi-mveliso.
Ukujonga phambili, kunye nenkqubela phambili eqhubekayo yezinto zesayensi kunye neenkqubo zokuvelisa, i-silicon carbide intonga yokufudumeza kombane kulindeleke ukuba ifezekise impumelelo enkulu ekusebenzeni kunye nokwandisa ngakumbi izicelo zabo kumashishini asakhasayo, afana nokulungiswa kwezinto ezintsha zamandla kunye nophando kwi-high-temperature superconducting materials. Ngeengenelo zabo ezinamandla zetekhnoloji, izinto zokufudumeza zombane ze-silicon carbide zisetelwe ukuba zibe yeyona nto iphambili yokuqhuba izinto ezintsha kunye nophuhliso kumashishini anobushushu obuphezulu.
