Pūwero Korehau Alumina mō te Tapahi me te Huri Tika
He mea hanga te pūwero korehau alumina a St.Cera mai i te 99.8% Al₂O₃ tino parakore me ngā awaawa korehau i hangaia kia tino tika. Ka tutuki i tā mātou kaha huri tika te papatahi o te 0.003mm me te whakarara o te 0.002mm, kia mau ai te pūwero kore-whakarara i te wā e tapatapahia ana, e huri ana i te taha o muri, me te tirotiro. He kaha piko teitei (361 MPa), he pakeke (16 GPa), me te pumau wera tae atu ki te 800°C te rauemi. Kei te wātea i roto i ngā whakatakotoranga porowhita tae atu ki te 600mm te diameter o waho (OD) me ngā āhua tapawhā tae atu ki te 1500mm te roa. He mea hanga motuhake ngā awaawa korehau (ngā tauira porowhita, radial, mātiti rānei) kia rite ki ngā whakaritenga tukanga motuhake. Ka tirotirohia ia pūwero ki te ine whakawhiti laser, ā, ka tukuna mai he pūrongo manatoko papatahi.
