Ceramic zvinhu, zvinonyanya kureva maindasitiri ceramics kana advanced ceramics, anoshandiswa munzvimbo dzakasiyana siyana dzeindasitiri, uko simba remagetsi uye kuramba kune ekunze masimba (senge ngura) ndizvo zvinonyanya kushanda zvinodiwa.Iko kupfeka kuramba ndiyo huru yekuita index kuyera iyo ceramic zvinhu.Kazhinji vanhu vanoshandisa kuoma kutonga kupfeka kuramba uye kusimba kwealumina ceramic zvinhu.Ndiko kuti, iyo yakakwirira kuoma, zviri nani kupfeka kuramba.Saka maitiro ekuyedza kuomarara maparamendi ekupfeka-resistant ceramics?
Kuoma ndeimwe yeakakosha uye anowanzo kuyerwa zvivakwa mualuminium ceramics.Inogona kutsanangurwa seyero yekushushikana kwegoho chero ceramic kana zvinhu.Kuomarara kunoratidza kuramba kweceramic kutsemuka, deformation, densification uye kutamiswa.Kazhinji kutaura, Vickers uye Knoop nzira dzinoshandiswa zvakanyanya pakuomarara kuyedzwa kwekeramics.Iyo Vickers tekinoroji ndiyo yakajairika.Inoyera kuoma kweceramics kana zvimwe zvinhu nekuyera saizi ye theindentation yakasiiwa ne indenter.Inokodzera zvikamu zviduku uye zvikamu zvitete.Inoshandisa indenter yedhaimani uye mutoro wakareruka kugadzira indentation pane izvo zviri kuedzwa.Iko kukosha kwekuoma kunogonawo kuva chiyero chekudzika kweiyo indentation inokonzerwa ne indenter.
Zvinoenderana nezvinodiwa zvakasiyana zvemusika wekuita kwealumina ceramics, Chemshun Ceramics inogadzira AL2O3 92%, AL2O3 95%alumina kupfeka zvinodzivirira ceramic zvinhu.Iyo alumina yemukati inokanganisa kuoma kwezvinhu zveceramic kune imwe nhanho, ndiko kuti, kupfeka kuramba.Vatengi vanogona kusarudza kupfeka-inodzivirira ceramics ine akasiyana alumina zvemukati zvinoenderana nezvinodiwa zvenzvimbo yekushanda.
