I-White Zirconia ZrO2 Iishafu zeCeramic eziqhutywayo Iishafti zokuqhuba iishafti ze-Aerocraft Engine Components
Intshayelelo yeMveliso
IZirconia inobulukhuni obugqwesileyo kunye nokuqina, ukumelana nokunxiba, kwaye inokufakelwa kombane okulungileyo kunye nokumelana neekhemikhali. Yinto eyomeleleyo, ehlala ixesha elide, eyomeleleyo, into leyo isetyenziselwa ukunxitywa kwecandelo kunye namalungu omatshini. I-thermal conductivity yezinto ze-zirconia iphantsi kakhulu (3w/m・K), ngoko Isetyenziselwa isithinteli sobushushu ngokunjalo.
I-zirconia ye-Yttria-stabilized zirconia ibonelela ngeenzuzo ezinjengokonyuka okukhulu kobomi be-shaft ngokunciphisa i-abrasion, ukunciphisa okubonakalayo kwingxolo (kwiimeko ezininzi), imvume ye-USDA yokuqhagamshelana neemveliso zokutya. Ukuba ixabiso alikhathazeki, i-yttria-stabilized zirconia iyindlela engcono yezinto eziphathekayo kune-alumina ceramics.
Iqinile kakhulu-i-zirconia iibheringi ze-ceramic kunye neeshafts zinxiba kancinci kwaye zihlala ixesha elide kuneebheringi zentsimbi.
Ukugqitywa komphezulu obalaseleyo - Uburhabaxa beekeramics ze-alumina ngokuqhelekileyo abukho ngaphezu kwe-0.15um, bugudileyo kakhulu kuneebheringi ze-alumina ceramic. Okukhona iibheringi zigudile, kokukhona ukukhuhlana kuyancipha, kwaye kokukhona kusebenza kakuhle.
I-non-magnetic & insulator yombane-Ukuba kukho iimfuno ezinzima kwindawo yokusebenza engeyiyo-magnetic, iibheringi ze-ceramic zifanelekile ngakumbi kuneebheringi zentsimbi.
Iipropathi ezibethayo ezinje ngoxinzelelo kunye namandla aguquguqukayo, ukuqina kokwaphuka.
Mhle kakhulu ukumelana nokuthotywa kwe-zirconia ceramics ziyakwazi ukumelana nomhlwa kwaye aziyi konakala njengeebheringi zentsimbi kwiimeko zealkali okanye zeasidi.
