Mukupinda munyika yemazuva ano yeindasitiri, munhu anogona kugara achiona kuvapo kwemhando chaiyo yezvinhu - hazvina kupenya sesimbi kana kureruka sepurasitiki, asi zvinotsigira chinyararire mashandiro eindasitiri yemazuva ano. Iyi imhuri yezvigadzirwa zvesimbi zvemaindasitiri, boka rezvinhu zvisiri zvesimbi zvisina kugadzirwa zvinozivikanwa nehunyanzvi hwazvo.
I. "Nhengo dzinozivikanwa" dzemhuri yezvigadzirwa zvesimbi zvemaindasitiri
Pakati pemhuri yezvigadzirwa zvesimbi zvemaindasitiri, kune nhengo dzinoverengeka dzinonyanya kuzivikanwa: Zvigadzirwa zvesimbi zveAlumina zvakafanana nemukoma mukuru akavimbika, zvinovimba nekudzivirira kupisa uye ngura, zvichiita basa rakakosha muzvikamu zvemagetsi nemidziyo yemakemikari; Zvigadzirwa zvesimbi zvesilicon nitride zvakafanana nevatambi vakareruka, zvine kuomarara kwezviumbwa zvesimbi uye kusimba kwesimbi, zvichiratidza kushanda kwakanaka mumabheringi nemidziyo yekucheka; Zvigadzirwa zvesimbi zvemafashoni, kwete chete zvine kupenya kwakafanana neparera asiwo zvine tekinoroji nhema ye "phase transformation toughening", inofarirwa zvikuru mumazino emazino uye zvikamu zvemagadzirirwo akakodzera.
II.Zviumbwa zvesimbi zvesilicon carbide: Murwi wepasi rose mumunda wemaindasitiri
Pakati pemhuri iyi, silicon carbide ceramics inogona kuonekwa semurwi wechokwadi. Iyi ceramic yakakosha inoumbwa nesilicon necarbon elements yakatanga kugadzirwa nevanhu muna 1905 uye yagara ichiputsa zvinyorwa zvekushanda kwezvinhu zvemaindasitiri. Yakaita senhoo yakagadzirwa nedhaimani, ine kuomarara kweMohs kusvika ku9.5, yechipiri chete kubva kudhaimani pachayo; yakafanana nenhumbi dzehondo dzakagadzirwa nezvidhinha zvisingashande, inokwanisa kutsungirira 1350℃ yekupisa kwakanyanya.
Munzvimbo yekugadzira simbi, simbi dzesilicon carbide dzakagadzirwa nesimbi dzinotsigira kudzimwa kwesimbi; mumapaipi emakemikari, inoshanduka kuita muchengeti anodzivirira ngura, zvichiwedzera hupenyu hwemapaipi; pamitsetse yekugadzira semiconductor, isarudzo yakanaka yekubata zvakanaka; zvinoshamisa kuti chinhu ichi chinoita sechinorema chinokonzeresa kupisa zvakanaka, zvichiita kuti chiwane nzvimbo yacho mumunda wekupisa kwemagetsi.
III. Kushanduka nekuzvarwa patsva kunounzwa netekinoroji
Tekinoroji yemazuva ano yapa silicon carbide ceramics hupenyu hutsva. Kuburikidza netekinoroji ye nanomodification, masayendisiti akawedzera kusimba kwayo; vachishandisa tekinoroji yekudhinda ye3D, zvikamu zvakaoma zvakafanana nemabasa ehunyanzvi zvinogona kugadzirwa. Murabhoritari yekambani yedu, mainjiniya vari kudzidza nzira dzekugadzira silicon carbide sintering, vachishandisa tekinoroji yepamusoro yekuumba silicon carbide kuti vasangane nezvinodiwa nevatengi uye vachiramba vachivandudza mashandiro ezvigadzirwa zvesilicon carbide ceramic, zvichivagonesa kugadzirisa mamiriro ekushanda akaomarara.
Kubva kuindasitiri yechinyakare kusvika kune tekinoroji yepamusoro-soro, zvigadzirwa zvesimbi zvemaindasitiri zviri kunyora ngano itsva. Semupi webasa rehunyanzvi hwekugadzira zvigadzirwa zvesimbi zvesilicon carbide, tinogara takazvipira kupa mhinduro dzakagadzirirwa isu. Ingave iri kugadzirisa zvikamu zvine chimiro chakakosha zvine hunyanzvi hwakakosha kana dhizaini yemhinduro dzekushandisa mumamiriro ekushanda akanyanya, tinogona kuwana rutsigiro rwehunyanzvi pano.
