Mbale Yopukutira ya Alumina Ceramic Yoyera Kwambiri Yopangira Kupaka Mwanzeru
St.Cera'smbale yopukutira ya ceramicAmapangidwa kuchokera ku alumina ya 99.8% yoyera kwambiri (Al₂O₃) yogwiritsidwa ntchito polumikiza ndi kupukuta molondola. Mphamvu yathu yolumikiza molondola imafikira kuphwanyika kwa 0.003mm, kufanana kwa 0.002mm, ndi kutha kwa pamwamba kwa Ra0.1, kuonetsetsa kuti zinthuzo zachotsedwa mofanana pamwamba pa mbale yonse. Mbaleyi imapereka kukana kwabwino kwambiri kwa kuvala (Vickers 16 GPa), mphamvu yopindika kwambiri (361 MPa), komanso kukhazikika kwa kutentha mpaka 800°C. Imapezeka mu mawonekedwe ozungulira mpaka 600mm m'mimba mwake ndi mbale zozungulira mpaka 1500mm kutalika. Malo okhala ndi mizere (m'lifupi mwa mizere 0.5–2.0mm) amapezeka kuti agawidwe mu njira zolumikizira. Mbale iliyonse imayesedwa ndi laser interferometer ndipo imaperekedwa ndi lipoti loyesa molondola.
