Karubide ya silicon (SiC) ni ibikoresho bikundwa cyane mu nganda zitandukanye bitewe n’ubukomere bwayo budasanzwe, ubushyuhe bwayo buhamye, ndetse no kudakoresha imiti. Mu moko yayo menshi, imiyoboro ya karubide ya silicon ihabwa agaciro cyane kubera kuramba kwayo no gukora kwayo mu bihe bikomeye. Iyi nkuru izasuzuma inzira igoye yo gukora.imiyoboro ya karubide ya silikoni, hibandwa ku gukora imiyoboro ya ceramic ya silikoni ikoze mu buryo bwa reaction-sintered.
Gusobanukirwa na Silicon Carbide
Mbere yuko twiga ku buryo bwo gukora, ni ngombwa gusobanukirwa icyo silicon carbide ari cyo. Silicon carbide ni imvange ya silicon na karuboni izwiho imiterere yayo idasanzwe. Ni semiconductor irwanya ubushyuhe bwinshi, oxidation, na corruption. Iyi miterere ituma imiyoboro ya silicon carbide iba myiza cyane mu nganda nko mu kirere, imodoka, no gutunganya imiti.
Gutegura ibikoresho fatizo
Intambwe ya mbere mu gukora imiyoboro ya silicon carbide ni ugutegura ibikoresho fatizo. Ifu ya silicon nziza cyane n'ifu ya karuboni ni ngombwa kugira ngo hakorwe silicon carbide ifite ubushobozi bwo gukora neza (RBSC). Ubuziranenge bw'iyi fu ni ingenzi cyane; umwanda uwo ari wo wose uzagira ingaruka zikomeye ku bwiza bw'umusaruro wa nyuma. Byongeye kandi, ingano y'uduce tw'ifu igomba kugenzurwa neza. Ingano y'uduce duto ituma ibikoresho bikora kimwe mu gihe cyo gutwika, bigatuma umusaruro wa nyuma uba mwinshi kandi ukomeye.
Ibikoresho n'Uruvange
Iyo ibikoresho fatizo bimaze gutegurwa, intambwe ikurikiraho ni ugushyira hamwe no kuvanga. Iyi gahunda ikubiyemo kugenzura neza igipimo cy'ifu ya silikoni n'ifu ya karuboni. Igipimo gikwiye ni ingenzi kuko kigena ingaruka z'imiti zizabaho mu gihe cyo gusya. Kuvanga neza ifu kugira ngo habeho gukwirakwira neza ni ingenzi kugira ngo habeho ikorwa rya silikoni. Iyi ntambwe ni ingenzi; kudahuza kw'uruvange gushobora gutera inenge mu muyoboro wa nyuma wa silikoni.
Gukora ishusho y'umuyoboro
Iyo igikorwa cyo gukusanya no kuvanga kirangiye, intambwe ikurikiraho ni ugushushanya umuyoboro. Ibi bishobora kugerwaho binyuze mu buryo butandukanye, harimo no gukanda bukonje (CIP) cyangwa gusohora. CIP ikubiyemo gushyira igitutu kimwe ku ifu ivanze mu gikoresho, bigatuma habaho imiterere mito kandi ikoze neza. Ubundi buryo, gusohora bituma ibikoresho bikomeza gushushanya, bikaba ingirakamaro cyane cyane mu gukora imiyoboro miremire. Guhitamo uburyo bwo gushushanya biterwa n'ingano wifuza n'ibipimo by'umusaruro wa nyuma.
Uburyo bwo gucukura
Uburyo bwo gutwika niho habera ubumaji. Umuyoboro wa silikoni wakozwe ushyirwa mu itanura rishyuha cyane hamwe n'umuvuduko ugenzurwa neza wo gushyushya n'igihe cyo gufata. Muri iki cyiciro, ifu ya silikoni n'ifu ya karuboni bikora mu buryo bwa shimi kugira ngo bikore imiterere ya silikoni ya silikoni. Ubushyuhe bwo gutwika ubusanzwe buri hagati ya 1400°C na 2000°C, bitewe n'uburyo runaka n'imiterere y'umusaruro wa nyuma. Iyi ntambwe ni ingenzi kuko igena imbaraga za mekanike n'ubushyuhe buhamye bw'umuyoboro wa silikoni.
Ikoranabuhanga nyuma yo gutunganya
Nyuma y’uko igikorwa cyo gutwika kirangiye, umuyoboro wa silicon carbide ukorerwa isuzuma nyuma yo gutunganya. Iki cyiciro kirimo gukora imashini no gusiga irangi ry’ubuso kugira ngo huzuzwe ibisabwa neza n’ubwiza bw’ubuso. Gukora imashini bishobora kuba birimo gukata, gusya cyangwa gucukura kugira ngo hagerwe ku bipimo bisabwa, mu gihe gusiga irangi ry’ubuso byongera ubwiza n’imikorere y’umuyoboro. Gukora isuzuma nyuma yo gutunganya ni ingenzi kugira ngo ibicuruzwa bya nyuma byuzuze amahame ngenderwaho y’inganda n’ibisabwa n’abakiriya.
Ingamba zo kugenzura ubuziranenge
Mu gihe cyose cyo gukora, dushyira mu bikorwa ingamba zo kugenzura ubuziranenge kugira ngo turebe ko imiyoboro ya silicon carbide yujuje ibisabwa. Ibi birimo gusuzuma ubuziranenge bw'ibikoresho fatizo, kugenzura uburyo bihora bivangwa, no kugenzura mu gihe cyo gutwika no nyuma yo gutwika. Ubuhanga buhanitse nka X-ray diffraction na scanning electron microscopy bushobora gukoreshwa mu gusesengura imiterere ya silicon carbide kugira ngo harebwe ko yujuje ibisabwa mu mikorere.
Gukoresha umuyoboro wa Silicon Carbide
Imiyoboro ya silicon carbide ikoreshwa mu buryo butandukanye bitewe n’imiterere yayo myiza. Mu nganda zitunganya imiti, ikoreshwa mu gutwara amazi yangiza, mu gihe mu rwego rw’indege, ikoreshwa nk’ibice bigize ahantu hashyuha cyane. Byongeye kandi, imiyoboro ya silicon carbide ikoreshwa cyane mu gukoresha ingufu, nko mu byuma bitanga ingufu za kirimbuzi na turbine za gaze, aho ubushobozi bwabyo bwo kwihanganira imimerere mibi ari ingenzi cyane.
Muri make
Gukora imiyoboro ya silicon carbide ni inzira igoye kandi yoroshye isaba kwitonda ku buryo burambuye kuri buri cyiciro. Kuva mu gutegura ibikoresho fatizo byiza kugeza ku kugenzura neza uburyo bwo gutwika, buri ntambwe igira uruhare runini mu bwiza no mu mikorere y'umusaruro wa nyuma. Uko inganda zikomeje gushaka ibikoresho bishobora kwihanganira imimerere mibi, icyifuzo cy'imiyoboro ya silicon carbide gishobora kwiyongera, bigatuma birushaho kuba ingenzi gusobanukirwa uburyo bwo kuyikora. Byaba bikoreshwa mu nganda cyangwa mu ikoranabuhanga rigezweho, imiyoboro ya silicon carbide ni intambwe ikomeye mu bumenyi bw'ibikoresho, itanga kuramba no kwizerwa mu bintu bitandukanye.
