Sanda Mai Ƙarfi Mai Girma na Zirconia - don Shafts & Punches Masu Daidaitawa
Sanda mai siffar zirconia ta St.Cera an yi ta ne da ƙarfe mai kyau daga ZrO₂ mai daidaita yttria. Tana da ƙarfin lanƙwasawa na musamman (1000 MPa), ƙarfin karyewa (5–8 MPa·m¹/²), da kuma taurin Vickers (13 GPa). Sanda tana da kamannin baƙi ko fari, yawanta 6.03 g/cm³, kuma babu ramuka. Diamita daga 1 mm zuwa 50 mm, tsawonta har zuwa 200 mm, tare da juriya mai ƙarfi kamar ±0.005 mm. An gama saman har zuwa Ra ≤0.2 μm. Ya dace da aikace-aikacen da ake amfani da su sosai kamar su plungers, shafts, dowels fils, da blank kayan aikin yankewa.

Aikace-aikace:
- · Pistons masu auna zafin jiki da kuma masu auna zafin jiki
- · Layukan dowel don daidaitawa
- · Kayan aikin yanke abubuwa marasa amfani (wukake, masu yanke abubuwa)
- · Na'urorin juyawa masu juyewa a cikin muhallin da ke lalata muhalli
Fa'idodi:
- · Ba shi da maganadisu, mai hana ruwa shiga ta hanyar lantarki (>10¹³ Ω·mm²/m)
- · Yana jure wa sinadarai masu ƙarfi (acids, alkalis banda HF)
- · Babu tsatsa ko hayaniya
Masana'antu:
Sandunan da aka yi wa fenti → niƙa ba tare da tsakiya ba zuwa daidai diamita → lapping/gogewa → tsaftacewa ta ultrasonic. Duba diamita 100% tare da ma'aunin laser.
