Munyika yemazuva ano ine magadzirirwo akarurama, kukanganisika kudiki kwezvinhu kunowanzo sarudza mashandiro ekupedzisira emidziyo.Zviumbwa zvesimbi zvesilicon carbide, nehunyanzvi hwazvo hwakasiyana, zviri kuva "muchengeti akasimba" akakosha mumunda wekugadzira wepamusoro-soro. Kusagadzikana kwakanyanya kwezvinhu zveceramic kunokonzerwa nekusachinja-chinja kuri kutsanangura patsva mwero wekushanda kwemidziyo chaiyo.
1, Kodhi yesainzi yakaoma
Modulus yesimbi inochinjika yakafanana neruler yekuyera kuomarara, ichinyatsoona kugona kwayo kuramba kuchinjika kana yamanikidzwa. Modulus yesimbi inochinjika yesilicon carbide ceramics inopetwa katatu kupfuura simbi yakajairika, izvo zvinoita kuti ifanane neskeleton yesimbi inosimbisa zvivakwa kana yamanikidzwa - kunyangwe kana iri pasi pemutoro wakasimba wemidziyo inorema, kuchinjika kwacho kunongova 1/4 chete yezvinhu zvesimbi.
Kuomarara uku kunoshamisa kunobva pachimiro chakasimba che covalent bond chiri mukati mechinhu chacho. Atomu yega yega yekabhoni yakabatana zvakasimba nemaatomu mana esilicon kuburikidza nekudyidzana kwakasimba, zvichigadzira chimiro che three-dimensional network crystal. Kana masimba ekunze achishanda, chimiro ichi chakasimba che lattice chinogona kuparadzira zvinobudirira kushushikana uye kudzora deformation mukati me micrometer range. Muminda yakaita semapuratifomu e optical accuracy uye michina yekugadzira semiconductor isingatenderi deformation, hunhu uhwu hunova kiyi yekuona kuti yakarurama.
2, Uzivi hwezvinhu zvinosanganisa kuomarara uye kuchinjika
Silicon carbide ceramics haingoratidzi kuomarara kwakanyanya chete, asiwo ine mashandiro anoshamisa akazara:
1. Yakasimba asi haina kuputsika: Simba rayo rekukotama rinodarika resimbi chaiyo, uye kunyangwe kana yamanikidzwa zvakaenzana nenzou yakakura yakamira netsoka imwe (inenge 400MPa), inogona kuramba yakasimba. Kusanganiswa uku kwesimba rayo guru uye kusimba kwayo kwakanyanya kunogadzirisa dambudziko reindasitiri rekuti zviumbwa zvechinyakare hazvina kuputsika.
2. Kugadzikana kwekupisa segomo: Kuwanda kwekupisa kwezvinhu zvacho kunongova 1/4 chete yesimbi, uye kushanduka kwehukuru kwacho kushoma mutsauko wekupisa we200 ℃. Pamwe chete nekupisa kwayo kwakanaka, inogona kukurumidza kuyera tembiricha uye kudzivirira kuunganidzwa kwekushanduka kunokonzerwa nekushushikana kwekupisa.
3. Kusachinja-chinja: Kana zvinhu zvikaramba zvichimanikidzwa, mwero wekukwira kwesilicon carbide wakaderera kaviri pane wezvinhu zvesimbi. Izvi zvinoreva kuti kunyangwe zvikaiswa mutoro mumwe chete kwemakore gumi, kuchinja kwechimiro chayo kunogona kudzorwa pasi pemuganhu wekuona michina.
3, Kukosha kwetekinoroji kwakasimba
Kugona uku kunoshamisa kwekudzivirira kushanduka kuri kugadzira mikana mitsva yeindasitiri:
Mumasystem ekuona esatellite, iva nechokwadi chekuti girazi rinochengetedza nanometer yakati sandara kana tembiricha yakakwira iri pakati penzvimbo.
Chengetedza kurongeka kwenzvimbo ye submicron yepuratifomu yekufambisa yemidziyo yekugadzira wafer ye semiconductor panguva yekushanda nekukurumidza.
Chengetedza kugadzikana kwechimiro chakavharwa chekamuri rekumanikidza remidziyo yekuongorora yakadzika mugungwa kunyangwe pasi pekumanikidzwa kwemvura kwemakiromita.
Tinoshandura mukana uyu wezvinhu kuita makwikwi ehunyanzvi kuburikidza nemaitiro matsva: kushandisa nzira dzekugadzira dzepamusoro-soro kuti tiwedzere huwandu hwezvinhu; Nekushandisa tekinoroji yepamusoro-soro ine patent, kusimba kunowedzerwa uku tichichengetedza kusimba kwakanyanya. Boka rega rega rezvinhu rinoedzwa zvakaoma kuona kuti zvigadzirwa zvinounzwa zvinosangana kana kutopfuura zvinodiwa nevatengi.
Nhasi uno, sezvo kugadzira nemazvo kuri kufambira mberi kusvika padanho repamusoro, zviumbwa zvesimbi zvesilicon carbide zviri kutsanangura chinangwa chikuru cheindasitiri yemazuva ano ne "pfungwa dzayo dzakasimba" - kushandisa kugadzikana kwakakwana kwezvinhu kutsigira mikana isingaperi yekugadzira. Kubudirira uku kwetekinoroji, uko kunomiririra huchenjeri hwesainzi yezvinhu, kucharamba kuchiisa simba idzva re "kushandisa kuomarara kukunda kuchinjika" mukugadzira michina yepamusoro-soro.
