Mowhiti Ārai PVD Alumina mō ngā Pūnaha Whakatakotoranga Kohu Tinana
Ko te mowhiti whakamarumaru PVD a St.Cera he mea hanga mai i te 99.8% alumina parakore-teitei (Al₂O₃) hei whakamahi i roto i ngā pūnaha whakatakotoranga kohu tinana (PVD). Ka whakaratohia e te mowhiti te wehenga hiko i waenga i ngā wāhanga o te rūma, ka ārai i te arc me te whakarite i te mahi plasma pumau. Ko ngā āhuatanga matua ko te kaha dielectric teitei (15×10⁶ V/m), te ātete motuhake >10¹⁴ Ω·mm²/m, me te pumau wera tae atu ki te 1600°C. Ka tutuki i ā mātou āheinga miihini tika ngā diameter o waho tae atu ki te 600mm, ngā diameter o roto tae atu ki te 0.2mm, te papatahi o te 0.003mm, me te mutunga mata Ra0.1. Ko te kore porosity me te koretake matū o te mowhiti ka whakarite i te pono mo te wa roa i roto i ngā taiao pupuhi kaha.
