Iithegi zeMveliso

I-siliconized graphite yinto edibeneyo apho i-silicon carbide ifakwe kumphezulu we-graphite substrate. Ineempawu zokuqina okuphezulu, amandla aphezulu omatshini kunye nokumelana nokunxiba kwe-silicon carbide, kunye neempawu zokuzithambisa kunye nokumelana nobushushu bobushushu begraphite. Yimathiriyeli efanelekileyo yokukhuhlana kunye nezixhobo zokutywinwa ngoomatshini, ezifanelekileyo ukutywinwa koomatshini beempompo zamanzi ezahlukeneyo, iimpompo zeoyile, iimpompo zekhemikhali, kunye neebheringi zeempompo eziphambili ezinesantya esiphezulu kunye nomthwalo ophezulu. Ukongeza, i-siliconized graphite inokumelana ne-oxidation elungileyo, ukuxhathisa ukothuka kwe-thermal, i-porosity ephantsi, kunye nokuhanjiswa kombane okuthile, kwaye inokusetyenziswa njengezinto ezinjengeentsimbi zokunyibilikisa iityhubhu kunye neetyhubhu eziyidrafti.

Ukuqulunqwa kwe-siliconizedigraphite iyunifomu, umphezulu uyahambelana nengaphakathi, kwaye umlinganiselo wokwakheka kwesilicon carbide kunye negraphite iyahlengahlengiswa. Okukhona uphezulu umxholo we-silicon carbide, kokukhona ubuninzi bezinto eziphathekayo, amandla oxinzelelo aphezulu, kunye nokumelana nokunyuka.

Umfanekiso we-metallographic wesiliconizedigraphite

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