Iithegi zeMveliso

I-graphite ene-siliconized yinto edibeneyo apho i-silicon carbide inamathele kumphezulu we-substrate ye-graphite. Ineempawu zobulukhuni obuphezulu, amandla aphezulu oomatshini kunye nokumelana nokuguguleka kwe-silicon carbide, kunye neempawu zokuzithambisa kunye nokumelana nobushushu bokuthuthumela kwe-graphite. Yizinto ezifanelekileyo zokungqubana kunye nezixhobo zokutywina koomatshini, ezifanelekileyo ukuvalwa koomatshini kweepompo zamanzi ezahlukeneyo, iipompo zeoyile, iipompo zeekhemikhali, kunye neebheringi zeepompo eziphambili ezahlukeneyo ezinesantya esiphezulu kunye nomthwalo ophezulu. Ukongeza, i-graphite ene-siliconized inokumelana okuhle kwe-oxidation, ukumelana nobushushu bokuthuthumela, i-porosity ephantsi, kunye nokuqhuba umbane okuthile, kwaye ingasetyenziswa njengezixhobo ezifana neziqhushumbisi zokunyibilikisa isinyithi kunye neetyhubhu zokudonsa.

Ukwakheka kwe-siliconizedI-graphite iyafana, umphezulu uhambelana nowangaphakathi, kwaye umlinganiselo wokwakheka kwe-silicon carbide kunye ne-graphite unokulungiswa. Okukhona umxholo we-silicon carbide uphezulu, kokukhona uxinano lwezinto lukhula, kokukhona amandla okucinezelwa aphezulu, kwaye ukumelana noxinzelelo kuyanda.

Umfanekiso we-metallographic we-siliconizedigrafayithi

(inxalenye emnyama yigraphite, inxalenye engwevu yisilicon carbide, kwaye inxalenye emhlophe yisilicon)
