Usha Dhoobada Zirconia ee Xoogga Sare leh - loogu talagalay Usha Saxnaanta iyo Feeraha
Usha dhoobada ah ee St.Cera's zirconia waa dhul sax ah oo laga sameeyay ZrO₂ oo yttria-xasilloon. Waxay bixisaa xoog dabacsan oo heer sare ah (1000 MPa), adkaanta jabka (5–8 MPa·m¹/²), iyo adkaanta Vickers (13 GPa). Usha waxay leedahay muuqaal madow ama caddaan ah, cufnaan 6.03 g/cm³, iyo dalool eber ah. Dhexroorka laga bilaabo 1 mm ilaa 50 mm, dhererkiisuna yahay ilaa 200 mm, dulqaadkuna waa mid adag sida ±0.005 mm. Dhammaystirka dusha sare wuxuu ku fidsan yahay ilaa Ra ≤0.2 μm. Ku habboon codsiyada duugga badan sida tuubooyinka, ulaha, biinanka goynta, iyo meelaha bannaan ee qalabka jarista.

Codsiyada:
- · Biinanka saxda ah iyo bistooladaha
- · Biinanka dowel-ka ee isku-xidhka
- · Qalabka jarista meelaha banaan (mindiyo, jeexyo)
- · Rulabyada roogga ee ku jira deegaannada daxalka leh
Faa'iidooyinka:
- · Ma aha birlab, koronto ahaan dahaadh leh (>10¹³ Ω·mm²/m)
- · Waxay u adkaysataa kiimikooyinka dagaalka badan (asiidhyada, alkali marka laga reebo HF)
- · Ma jiro miridh ama xawaash
Wax soo saarka:
Usha wasakhaysan ee bannaan → shiidi aan dhexe lahayn ilaa dhexroorka saxda ah → laalaab/nadiifin → nadiifinta ultrasonic. Kormeer dhexroor 100% ah oo leh mikrometer laysar ah.
