Amashuka ya Ceramic arwanya kwambarwa na Alumina: Ibisubizo by'imyenda yo mu nganda ikora neza cyane

Impapuro za ceramic zidashobora kwangirika za alumina ni ibikoresho bya ceramic byo mu nganda bikozwe ahanini muri aluminium oxyde (Al₂O₃) kandi bigashyirwa ku bushyuhe bwinshi. Izi mpapuro akenshi zigera ku bukomere bwa Mohs bwa 8-9. Binyuze mu miterere yihariye y'ubuso, nko ku buso bwo hasi bukozwe mu miyoboro, imiraba, cyangwa kole ifite imiterere ya dot-matrix, imbaraga zo gufatanya n'ibikoresho by'icyuma zirushaho kwiyongera cyane. Bikoreshejwe hamwe n'udupira twa ceramic-metal, izi mpapuro zishobora gukora neza mu bidukikije kugeza kuri 350°C igihe kirekire, hamwe n'ibindi bikoresho bihangana n'ubushyuhe bwa 500°C. Ubucucike bwazo ni hafi 3.6 g/cm³, kimwe cya kabiri cy'icyuma, bigagabanya neza umutwaro w'ibikoresho.

Impapuro za ceramic zirinda kwangirika kwa aluminaBitanga ubushobozi bwo kudashira neza, kandi ubuzima bushobora kuba inshuro zirenga 100 z'icyuma cya manganese n'inshuro zirenga 20 z'icyuma cya chromium, bitewe n'imiterere y'akazi. Impapuro zifite ingingo zijimye n'imirongo y'imirongo ifunze zikoresha igishushanyo cy'ikigega cya kole, gituma kole itemba kandi ikazura munsi y'umuvuduko, bigatuma ubuso bufatana burushaho kuba bwiza mu gushyiraho. Ibi bintu bituma bikoreshwa cyane mu nganda nko mu bushyuhe, mu byuma, sima, no mu bucukuzi bw'amabuye y'agaciro, cyane cyane ahantu hashaje cyane nko mu miyoboro y'amakara, mu gutandukanya ifu ikomeye n'iy'ifu nziza, hamwe n'imashini zishyushya.
