Silicon carbide itanura ifite imbaraga nyinshi, ubukana bwinshi, kurwanya neza kwambara, kurwanya ubushyuhe bwinshi, kurwanya ruswa, kurwanya ubushyuhe bwiza no guhangana n’ihungabana, imiyoboro minini y’amashyanyarazi, kurwanya okiside nziza nindi mirimo myiza, ikoreshwa cyane cyane mu guta inshuro ziciriritse, ubushyuhe butandukanye itanura ryo kuvura, metallurgie, inganda zikora imiti, imyitozo yicyuma idafite ferro nindi myuga.
Ibiranga silicon carbide itanura
Silicon carbide itanura ni silicon karbide nkibikoresho nyamukuru, ibicuruzwa byiza bya kariside ya silicon bikozwe nubushyuhe bwo hejuru, hamwe nubushyuhe bwo hejuru, ubushyuhe bwihuse bwumuriro, imbaraga nyinshi, ubukana bwinshi, kwihanganira ubushyuhe bwiza, kurwanya ubushyuhe bwiza no kurwanya umutingito, byiza ubushyuhe bwumuriro, kurwanya okiside nziza nibindi bikorwa byiza kumpera zombi zo gushiraho ubushyuhe budasanzwe bwo hejuru.Irashobora kwirinda neza kwangirika kwicyuma cyibikoresho byo gushyushya amashanyarazi (harimo inkoni ya silikoni, insinga zishyushya amashanyarazi, nibindi), hamwe nogukoresha cyane imiyoboro ya kariside ya karubide irinda ibyuma bifite ibipimo bitandukanye kurenza ibyo bicuruzwa bitandukanye bya grafite bifite ubushyuhe bwumuriro, Kurwanya okiside, kurwanya ubushyuhe, no kurwanya ubushyuhe bwinshi
Gukora tekinoroji ya silicon karbide itanura
Igicuruzwa ni karibide ya silikoni nkibikoresho byingenzi, binyuze muburyo bwihariye bwubushyuhe bwo hejuru bwo gutwika ibicuruzwa byiza bya karubide nziza, uburebure burashobora gutegurwa ukurikije ibyo abakiriya bakeneye.
Ikoreshwa ryambere rya silicon karbide itanura
Ikoreshwa cyane mumahugurwa yicyuma kitari ferrous, sisitemu ya aluminiyumu sisitemu yo gutesha agaciro, imashini zo gucapa no gusiga amarangi, amahugurwa ya zinc na aluminium no gutunganya ibicuruzwa nindi myuga.
Iterambere ryinganda za silicon karbide itanura
Itanura rya silicon carbide itanura rifite ibiranga kwinjiza kwinshi, urusaku ruke, umurongo mwiza, nibindi.Ugereranije nibice bya MOSFET, ibice bya JFET ntabwo bifite ibibazo byokwizerwa biterwa nubusembwa bwa ogisijeni yumuryango no kugabanya umuvuduko muke wabatwara, kandi bikomeza ubushobozi bwimikorere yumurongo mwinshi bitewe nibikorwa biranga unipolar.Mubyongeyeho, ibikoresho bya JFET bifite imikorere myiza ihamye kandi yizewe mubushyuhe bwinshi.Bitewe n'imiterere ya electrode yo mumarembo ya silicon carbide igikoresho cya JFET, voltage yinjirira ya JFET mubusanzwe iba ari mibi, ni ukuvuga ko hariho ibikoresho byinshi bisanzwe, bikaba bidakwiye cyane kubikoresha mubijyanye na electronics power, kandi ni ntibishobora kubangikanya na sisitemu yo kugendana kwisi yose.Mugutangiza ibikoresho byikoranabuhanga byo gutera inshinge cyangwa imiterere ya mesa groove, igikoresho cyongerewe imbaraga hamwe na leta isanzwe ikora.Nyamara, kubera ko ibikoresho byongerewe imbaraga ahanini byakozwe mugiciro cyibintu bimwe na bimwe biranga imbere-birwanya, biroroshye kugera kumurongo mwinshi wimbaraga nubushobozi bwubu bwo guhora-gucika (ubwoko bwa depletion) JFET, nuburyo bwo guhuza depletion andika ibikoresho bya JFET kumurongo wo hejuru wagerwaho muguhuza ingufu nke za Si zo mu rwego rwa MOSFETs murukurikirane.Umuzunguruko wa disiki yibikoresho bya JFET isanzwe isanzwe ihujwe numuzunguruko wibikoresho bya silicon rusange.Imiterere ya caskade irakwiriye cyane kuri voltage nini nibisohoka cyane, kuruta ibikoresho bya silicon gakondo IGBT, birinda byimazeyo ikibazo cyo guhuza ibibazo byumuzunguruko.
Ibyiza bya silicon karbide nibi bikurikira.
1, imikorere yo kohereza ubushyuhe nibyiza, urukuta rwigituba ruto (milimetero nkeya), ibisubizo byubushyuhe bwibicuruzwa birashyuha cyane;
2, ntabwo byatewe na ruswa
3, ubushyuhe bwo hejuru ntibushonga, ibyuma byanduye bidafite umwanda;
4, irashobora gukoreshwa mugushonga sodium na strontium ikungahaye cyane;
5, isura yibicuruzwa ntabwo ifatanye na slag, kurinda biroroshye cyane;
6, ubushyuhe bwo hejuru burwanya 1600;
7. Kurwanya ubukana bukabije
8, gukomera cyane, ntabwo byoroshye kumeneka
9 Igiciro-cyiza, ubuzima burenze igice cyumwaka.
Ibyavuzwe haruguru nibikorwa biranga silicon karbide itanura, niba ukeneye kumenya byinshi, urashobora kutwandikira!
