Igrafu yesilika ye-silicon carbide, njengezinto ezibalulekileyo kwiinkqubo ezahlukeneyo zemizi-mveliso, zijongana neengxaki ezinokubakho ngenxa yokusetyenziswa kwexesha elide. Ii-cracks ze-ixesha elide zaqwalaselwa kwiindonga ezihlambeli, zibonisa isiphene esinokubakho esinokubeka esiphelweni kunye nokhuseleko lwayo.
Omnye we-on malungana nokuqapheleyo yayikukuphuhliswa kwe-rack ye-crack enye ye-chededinal ukusuka kumda ophezulu wokubethelelwa. Oku kunokwenzeka ngenxa yokufudumeza ngokukhawuleza, ngakumbi xa ezantsi kunye nemiphetho esezantsi ivezwe kumaqondo obushushu aphezulu kuneqonga. Ukongeza, ukusetyenziswa kwezitho ezinqabileyo ezingalunganga okanye ifuthe kumda ophezulu we-ingot kunokukhokelela ekumiselweni kwezi rocks.
Ukongeza, ubukho beendlela ezininzi zokuhamba kwexesha ezihambayo ukusuka kumda ophezulu wezinto ezithe nkqo. Le phenonon inokuthi ihambelane noxinzelelo oluxhaswe ngokuthe ngqo kwi-lource kwi-leaces kwi-bible okanye ubukho bomsantsa ophakathi phakathi kwewonga yeziko kunye nokubethelelwa. Ezi meko zinokukhokelela ekunyukisweni kwe-oxidation, ekugqibeleni zibangela ukuba izicukube zibumbe kwaye zityeshele ingqibelelo yayo.
Ukongeza kwimingxunya kumda ophezulu, ii-cracks ze-ixesha elide nazo zafunyanwa kumacala ezinto ezinqabileyo. Ezi cengs zihlala zibangelwa luxinzelelo lwangaphakathi, zihlala zibangelwa kukubeka i-Wedge epholileyo yezinto ezipholileyo zezinto ezichongiweyo kamva ziye ezinqeni. Ukwanda kwezinto ezenziwe ngomtshato xa usafudula kunxunguphele kwingcinezelo enkulu, ekhokelela kuphuhliso lwe-rocks kunye nomonakalo onokubakho.
Ubukho bale mifula luphawu olucacileyo lokuba imbeko inokusondela okanye ifikelele esiphelweni sobomi bayo obuluncedo. Ukuncipha kodonga olunxilisayo kwi-crack ngakumbi izinto ezibalaseleyo ukuba kungakwazi ukumelana noxinzelelo olukhulu, ebeka umngcipheko omkhulu kwinkqubo yemizi-mveliso esetyenziswa kuyo.
Ukujongana nale micimbi kubalulekile ekuqinisekiseni ukuba iinkqubo zeshishini zixhomekekeigrafu yesilika ye-silicon carbide Qhubeka nokusebenza ngokukhuselekileyo nangokufanelekileyo. Abasebenzi bemizi-mveliso kunye nabasebenzi bolondolozo kufuneka babeke esweni imeko yeigrafu yesilika ye-silicon carbide kwaye uthathe amanyathelo asebenzayo ukunciphisa umngcipheko wokuphumelela kwesakhiwo.
IProtokholi eqhelekileyo kunye nolondolozo kufuneka isungulwe ukufumanisa iimpawu zangaphambili zokunxiba kunye nomonakalo. Ukongeza, iindlela ezifanelekileyo zokufudumeza kunye nokusetyenziswa kwezixhobo ezifanelekileyo zokuphatha (ezinjengeengfins ezihlekisayo) kubalulekile ukuthintela ukwenziwa kwee-rocks kwaye kuqinisekiswe izinto eziludakulelekanga kwindawo enokubekwa emgceni.
Ukongeza, uyilo kunye nokusebenza kweziko kufuneka kuhlolwe ngononophelo ukunciphisa uxinzelelo ngqo kwi-contracy kunye nokukhusela i-oxidation egqithisileyo, enokukhokelela ekumiselweni kwe-rocks. Ukuthatha amanyathelo okulawula uxinzelelo lwangaphakathi, ngakumbi xa ujongene nezinto ezandisayo xa ushushu, kubalulekile ukukhusela ukubethelelwa komonakalo.
Ngesishwankathelo, ubukho be-cracks yexesha elide ngaphakathiigrafu yesilika ye-silicon carbide Ifuna ukuqwalaselwa kwangoko kunye nokulungisa amanyathelo okuthintela iingozi ezinokubakho kunye nokuphazamiseka kwiinkqubo zemveliso. Ngokubeka phambili ulondolozo rhoqo, iinkqubo ezifanelekileyo zokuphatha kunye nemisebenzi yecebo, amashishini anokukhusela ukuthembeka kwaboigrafu yesilika ye-silicon carbide kwaye ugcine ukuthembeka kwemisebenzi yabo yokwenza kunye nemveliso.
