Zvigadzirwa zve alumina zvakakangwa: zvinhu zvepamusoro zvine mashandiro akanaka kwazvo

Zviumbwa zveAlumina zvinoshandiswa zvakanyanya muminda yakawanda nekuda kwezvakanaka zvazvo zvakaita sekuomarara kwakanyanya uye kugadzikana kwakasimba kwemakemikari. Zvisinei, kuputsika kwazvo kunoderedza hunyanzvi hwazvo. Zviumbwa zveAlumina zvakasimba zvakavapo uye zvakagadzirisa dambudziko iri zvinobudirira.

 Zviumbwa zvesimbi zvealumina zvakakangwainogona kusimbiswa nenzira dzakasiyana-siyana. Dzakajairika dzinosanganisira zirconia toughening, iyo inovandudza zvakanyanya kuomarara nekuwedzera ZrO₂ kualumina uye kushandisa phase change yayo nedzimwe nzira; whisker nefiber toughening, kuwedzera SiC, Si₃N₄ whiskers kana C, SiC fibers kuwedzera nzira dzekupararira kwe crack uye kushandisa simba rekupwanyika; particle toughening ndeyekuwedzera high elastic modulus particles dzakadai seSiC neTiC kuti dzisapararire uye dzibvise maburi.

 Simba rekuchinjika uye simba rekukanda kwesimbi dzesimbi dzealumina dzakasimba zvinovandudzika zvikuru. Semuenzaniso, simba rekukanda kwesimbi dzesimbi dzealumina dzakasimba dzezirconia dzinogona kusvika 480MPa, uye simba rekukanda kwesimbi i7MPam1/2.

 Panyaya yekushandiswa kwayo, mune zvehutano, inoshandiswa kugadzira ma implants emazino nemajoini ekugadzira nekuda kwekushanda kwayo zvakanaka uye kuomarara kwakanyanya, izvo zvinogona kuderedza matambudziko; mumunda we semiconductor, se substrate yekurongedza zvishandiso, inoshandiswa mumagetsi emota dzemagetsi IGBTs, nezvimwewo nekuda kwekupisa kwayo kwakanaka, insulation uye simba remakanika; muzvishandiso zvekucheka, inogona kuramba yakagadzikana pakupisa kwakanyanya uye kuita kuti iron ne alloys zvigadzirwe. Toughened alumina ceramics dziri kupenya muminda yakawanda nekushanda kwadzo kwakanaka. Chemshun ceramics inopa toughened alumina ceramics ine supper abrasion resistance uye impact resistance ye bulk material handling system.
