Sei alumina ceramics isingagoni kupfeka zvakanyanya?

Zvigadzirwa zveAlumina zvinodzivirira kupfekwa zvakanyanya, kunyanya nekuda kwehunhu hwazvo hwakasiyana hwe microstructure uye makemikari.

Chekutanga, chimiro chidiki che alumina ceramics chimiro chakaita sepolycrystalline chakaumbwa nezvidimbu nemasero, izvo zvinoita kuti chive nesimba guru remakanika. Chechipiri, alumina ceramics chinhu chakaoma zvikuru, kuoma kwayo kwakafanana nedhaimani, kwakaoma kupfeka, saka ine resistance yakanyanya. Chechitatu, hunhu hwemakemikari e alumina ceramics hwakagadzikana zvikuru, hunodzivirira kuputsika kweacids dzese, mabhesi nemunyu nezvimwe zvinhu zvemakemikari, uye hahuna kukanganiswa nechero rudzi rwekuora kwemakemikari.

Zvigadzirwa zveAlumina zvakakamurwa kuita mhando dzakasiyana dzehutsanana, uye huwandu hweAl2O3 hwakakwira muzvigadzirwa zveAlumina zvakachena. Kazhinji, huwandu hwealuminium hwakakwira, hunowedzera kuramba kwayo kupfeka.

Pamusoro pe,zviumbwa zvesimbi zvealuminainewo kugadzikana kwakanaka kwazvo kwekupisa, inogona kuchengetedza mashandiro akanaka kwazvo pakupisa kwakanyanya, izvo zvinoita kuti mumamiriro mazhinji ekushanda anodzivirira kusakara inogona kutamba mashandiro akanaka.

Saka, hunhu uhwu hwezviumbwa zve alumina zvinoita kuti zvishande zvakanaka munzvimbo dzakawanda uko zvinoda kuramba kupfeka.
