Muminda yekucheka-kumucheto senge semiconductors, simba idzva, uye aerospace, greyish-dema dema ceramic zvinhu zviri kuita chinyararire basa rakakosha. Zvirisilicon carbide ceramic- chinhu chine kuoma kwakaenzana nedhaimondi, iyo iri kushandura chiso cheindasitiri yemazuva ano chaizvo nekuda kwekushomeka kwayo kwepamusoro-tembiricha, kusadzivirirwa kwecorrosion uye high thermal conductivity. Asi zvishoma zvinozivikanwa ndezvekuti kushandura iyo yakaoma silicon carbide poda kuita chaiyo midziyo, mashiripiti "yepamusoro-tembiricha yekugadzira" inodiwa.
I. Sintering Process: Mashiripiti Akakosha Kushandura Matombo kuita goridhe
Kana silicon carbide poda inofananidzwa nejade isina kukwenenzverwa, iyo sintering ndiyo nzira yakakosha yekuiumba kuita chigadzirwa chakanaka. Kuburikidza nepamusoro-tembiricha yekugadzira pa800-2000 ℃, micron-sized poda particles re-” zunza maoko “paatomu pamwero, kugadzira muviri wakakora uye wakasimba weceramic. Yakasiyana sintering maitiro, senge akasiyana ekunyora matekiniki, endow zvinhu zvine akasiyana ekuita maitiro:
1. Atmospheric pressure sintering: Iyo yakajairika "inononoka steering pakupisa kushoma"
Sezvinongoita soup inonaka yakabikwa zvishoma nezvishoma inoda kukwizwa pakupisa kwakadzikira, kuita uku kunoita kuti hupfu huwedzere kusimba kuburikidza nematembiricha akareba. Kunyangwe kutenderera kwacho kuri kureba, kunogona kuchengetedza "yepakutanga kunhuhwirira" kwechinhu uye yakanyatsokodzera semiconductor michina yemidziyo ine yakasimba kuchena zvinodiwa.
2. Kupisa-kudzvanya sintering: Iyo yakanyatsodzorwa "high-pressure forging technique"
Kushandisa mechanical pressure munzvimbo yepamusoro-tembiricha yakafanana nekupa chaiyo "hot compress massage" kune zvinyorwa, izvo zvinogona kukurumidza kubvisa mukati ma voids. Zvikamu zveceramic zvinogadzirwa neichi maitiro ane density padyo neiyo theoretical kukosha uye isarudzo yakanaka yekugadzira chaiyo mabhengi uye zvisimbiso.
3. Reaction Sintering: Iyo "Chemical Magic" Munyika Yezvinhu
Nekushandisa zvine hungwaru kuita kwemakemikari pakati pesilicon nekabhoni, iyo voids inozadzwa otomatiki panguva yekupisa. Ichi "kuzviporesa" chimiro chinoita kuti chive chishandiso chine simba chekugadzira zvikamu zvakaoma uye zvisina kujairika, zvakakodzerwa zvakasiyana-siyana zvinodzivirira kutonhora, kusapfeka, zvigadzirwa zvinodzivirira corrosion kana zvimwe zvikamu zvakagadziridzwa.
Ii. Kusarudzwa kweMaitiro: Uchenjeri hweKugadzira Kuti Ukwane
Sezvinongoita vagadziri vepamusoro vanosarudza masitichi zvichienderana nehunhu hwejira, mainjiniya anofanirwa kunyatso funga nezvezvinodiwa zvechigadzirwa:
Paunenge uchibata nenhengo dzakatetepa-dzakakomberedzwa dzisina kuumbwa, iyo "tekinoroji yekupinda" yekuita sintering inogona kuchengetedza chimiro chakakwana.
Semiconductor matireyi ane zvakaomesesa zvinodiwa kune ekupedzisira-flat nzvimbo anogona kuona zero deformation kuburikidza neyakajairwa kumanikidza sintering.
Paunenge uchibata neyakakura-mutoro zvinhu, iyo yekupedzisira-yakakwira density yekupisa-kudzvanya sintering inowanzosarudzwa.
Iii. Invisible Technological Breakthroughs
Munhoroondo yekushanduka-shanduka ye sintering tekinoroji, zviviri zvakavanzwa zvitsva zvinonyanya kukosha: kuwedzera kudiki kwekuwedzera kweSintering AIDS kwakafanana ne "molecular glue", iyo inoderedza kushandiswa kwesimba uchiwedzera simba; Iyo yedhijitari tembiricha yekudzora sisitimu inofananidzwa ne "akangwara chef", inochengeta tembiricha yekuchinja mukati ± 5 ℃ uye nekuona kuenderana kwekuita kwebatch yega yega yezvinhu.
Kubva kumunda weindasitiri usingapfekere uye usingadziviriri mukuora kusvika kune yepamusoro semiconductor indasitiri, silicon carbide ceramics iri kugadziridza mamiriro eindasitiri yemazuva ano. Iko kuenderera mberi kwekuvandudza tekinoroji yeSintering kwakafanana nekupa mapapiro kune iyi yemashiripiti zvinhu, zvichiita kuti ibhururuke ichienda kune yakakura application denga. Semugadziri ane hunyanzvi akabatanidzwa zvakanyanya mumunda wesilicon carbide ceramics kweanopfuura makore gumi, Shandong Zhongpeng anonzwisisa nhaurirano pakati pezvishandiso nekudzora kupisa zvirinani kupfuura chero ani zvake. Kugadziriswa kwega kwega kwe sintering curve ndiko kudzokororwa kwe "temperature-pressure-time" yegoridhe triangle. Kupenya kwechoto chega chega nemoto kunoenderera mberi nekunyora chitsauko chekushanduka-shanduka chezvigadzirwa zvemaindasitiri. Tichivimba neruvimbo rwekutsvagisa yakazvimirira uye budiriro uye akawanda patented matekinoroji, isu tinogara takazvipira kupa vatengi mhinduro imwe chete kubva pakucheneswa kwezvinhu zvakasvibirira kusvika kune chaiyo sintering, kuve nechokwadi chekuti silicon carbide ceramic chigadzirwa chinotakura kudziya kwemakore gumi ehunyanzvi. Nzira iri mberi yakapfava, uye kuburikidza nekudzokororwazve, inova itsva. Tinokukoka zvapachokwadi kuti ubatane nesu mukupupurira kuti pfundo iri rouchenjeri muzvigadzirwa zvemaindasitiri rinovhenekera sei zvimwe zvisingagoneki. Isu tinogara tichitenda kuti kufambira mberi kwese kwesainzi yemidziyo kuri kuunganidza simba rekuti vanhu vatyoke nemuganho wetekinoroji.
