Iiceramics ze-alumina ze-polycrystalline Al2O3 ezenziwe ngokwezifiso zokumelana nokuguguleka kobushushu obuphezulu

Ukusebenza kwe-aluminium oxide ceramics

1--Ubunzima buphezulu

Ubunzima be-alumina ceramics eRockwell yi-HRA80-90, ilandela idayimani kuphela ngobunzima, ingaphezulu kakhulu kunentsimbi engagugiyo kunye nokumelana nokuguguleka kwentsimbi engagqwaliyo.

2--Ukumelana kakuhle nokunxitywa

Ukumelana nokuguguleka kwe-alumina ceramics kufana nokuguguleka kwentsimbi ye-manganese izihlandlo ezingama-266 kunye nentsimbi ye-chromium ephezulu izihlandlo ezili-171.5. Phantsi kweemeko ezifanayo zokusebenza, inokwandisa ubomi benkonzo yesixhobo ubuncinane izihlandlo ezilishumi.

3--Ubunzima obuKhaphukhaphu

Uxinano lweeseramikhi ze-alumina yi-3.7~3.95g/cm°, nto leyo eyisiqingatha nje sentsimbi nentsimbi, kwaye inokunciphisa kakhulu umthwalo wezixhobo.

4--Uluhlu olubanzi lwezicelo

Iiceramics ze-alumina zisetyenziswa kakhulu koomatshini, kwi-fiber optics, kwizixhobo zokusika, kwezonyango, ekutyeni, kwiikhemikhali, kwi-aerospace nakwezinye iindawo.

Iingenelo ze-alumina ceramics:

1--Iiseramikhi zeAlumina zineempawu ezintle zokuthintela ubushushu. Ukulahleka kwamaza aphezulu kuncinci xa kuthelekiswa, kwaye ukuthintela ubushushu obuphezulu kulungile.

2--Iiseramikhi zeAlumina zinokumelana nobushushu, zinomlinganiselo omncinci wokwanda kobushushu, zinamandla aphezulu oomatshini kwaye ziqhuba kakuhle ubushushu.

3--Iiseramikhi zeAlumina zinokumelana neekhemikhali kunye nokumelana nesinyithi esinyibilikisiweyo.

4--Iiseramikhi zeAlumina azitshi, azilula ukuzigqwala kwaye ziqinile kwaye azilula ukuzilimaza, kunye nezinye izinto eziphilayo kunye nezinto zesinyithi azinakuthelekiswa nomgangatho ogqwesileyo.

5--I-Alumina ceramics inamandla okuguguleka, ubulukhuni kunye ne-corundum ziyafana, zinokufikelela kubulukhuni be-Mohs 9, ubulukhuni bayo bokuguguleka bunokuthelekiswa nee-alloys ezinzima kakhulu.
