Kubva pamapombi ekufambisa kuenda kumotokari dzesimba idzva, kubva kumagetsi ekupisa kusvika kumasatelliti emuchadenga, chinhu chinonzi "industrial diamond" chiri kunyora chinyararire miganhu yekugadzirwa kwemazuva ano.Silicon carbide ceramics, chinhu chakanyanya kuoma chine kuoma kwechipiri kune dhaimondi rechisikigo, chiri kukonzera chimurenga chinyararire munzvimbo dzakasiyana-siyana dzakadai semaindasitiri emazuva ano, semiconductors, aerospace, uye simba idzva nekuda kwekudzivirira kwayo kwekushisa kwepamusoro, kuramba kwakasimba kwemwaranzi, uye kunaka kwekushisa kwekushisa.
Kana 'mapfupa akaoma' akasangana nemazvo kugadzira
Kana ma ceramics echinyakare ari ebhuruu uye chena porcelain mune zvehunyanzvi uye mhizha, saka silicon carbide ceramics yakafanana newachi dzeSwitzerland mune zvakaringana zviridzwa. Kuomarara kwayo kunosvika 3-5 zvakapetwa kupfuura zveceramics, uye kuomarara uku padhuze nemadhaimani echisikigo kunoita kuti machining aite sekuveza pamahwendefa esimbi - maturusi akajairwa ekucheka anopera nekumhanya kunoshamisa panguva yekucheka. Chinotonyanya kuoma ndechekuti "zvakaoma" hunhu hwesilicon carbide hunoita kuti iite mutsauko nekukanganisa kudiki panguva yekugadziriswa, kunyanya kune dzimwe dzakatetepa-madziro dzakatetepa dzinoda kungwarira kwakafanana sekristaro artworks.
Asi kudiwa kweindasitiri yemazuva ano kuri kufambisa budiriro yetekinoroji. Mainjiniya vakaona kuti kiyi yekugadzirisa dambudziko iri iri mukubatanidzwa kwekuomarara uye kuchinjika: kuchengetedza emukati zvimiro zvechinyorwa uchiri kushandisa chaiyo kutonga panguva yekugadzirisa. Kungofanana nevabiki vepamusoro vanoziva kupisa, nzira dzemazuva ano dzekugadzirisa zvishoma nezvishoma izvi zvakasindimara kuburikidza nekudzora chaiko tembiricha, kudzvanywa, uye frequency yekudengenyeka.
Makiyi matatu ekuvhura madhaimani emaindasitiri
1. Kupisa kuumba kuumba
Iyi ndiyo imwe yedzakajairika nzira dzekugadzirisa silicon carbide ceramics. Iyi nzira inoisa silicon carbide poda kana yakasanganiswa poda mune inopisa yekudzvanya mold uye inoigadzira kuita chimiro pasi pekupisa kwakanyanya uye kumanikidzwa. Iine hunyanzvi hwekugadzira uye kuumba huroyi, uye inokodzera kugadzira hombe-yakakura silicon carbide ceramic zvigadzirwa senge maturusi ekucheka, inopisa inodhonzwa mahwendefa ealuminium, nezvimwe.
2. Grouting molding
Iyi inzira yakaderera-uye inokurumidza kuumba nzira yesilicon carbide ceramic zvigadzirwa. Iyi nzira inosanganisa silicon carbide poda nezvimwe zvinowedzera, inovawedzera kumvura kuita slurry, uye inoibaya muforoma. Zvadaro, inogadziriswa uye inoumbwa kuburikidza nekuomeswa uye yakakwirira-kupisa sintering, ine pfupi yekugadzirisa kutenderera uye mutengo wakaderera. Inokodzera kugadzirira yakakwirira-yakasimba, yakakwirira-density zvikamu uye zvinotakura zvinotakura zvikamu.
3. Poda metallurgy
Powder metallurgy inzira yekusanganisa uye kuumba silicon carbide poda mune imwe chikamu, uye wozoinyudza pakupisa kwakanyanya uye kudzvanywa. Iyi nzira ine maitiro akareruka ekugadzira, akasiyana echigadzirwa maumbirwo, uye yakakwira kugadzirisa, ichiita kuti ive yakakodzera kugadzira yakakwirira-chaiyo, yakakwirira-kusimba, uye inopfeka-inodzivirira zvigadzirwa zveceramic.
Kubva pamasamples emurabhoritari kusvika pakugadzirwa kwakawanda pamutsetse wekugadzira, budiriro mukugadziriswa kwesilicon carbide ceramics inosimbisa chokwadi: hapana zvinhu zvisingakwanisi kugadziriswa, tekinoroji chete isati yaputswa. Nekukura kwetekinoroji nyowani senge laser processing uye microwave sintering, iyi yaimbove inotyisa zvinhu iri kuvandudzwa mumafekitori akangwara, ichipinza simba rakaomarara mu "Chinese yakangwara kugadzira".
Mugungwa rakakura rekutsvagisa nzvimbo uye girinhi yakasvibira yesimba rakachena, silicon carbide ceramics vari kunyora ngano yeindasitiri yenguva ino nerunako rwavo rwakasiyana. Kuratidzirana uku pakati pekuomarara nehungwaru kungave mufananidzo usingaperi wevanhu vachityora miganhu yetekinoroji.
