Magnesia-stabilized zirconia (MSZ) imatha kupirira kukokoloka komanso kugwedezeka kwa kutentha. Tizilombo tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'onoting'ono timayambira mkati mwa magawo a cubic gawo la zirconias zolimba ngati zirconia yokhazikika ya magnesium. Pamene fracture ikuyesera kudutsa muzinthuzo, izi zimasintha kuchokera ku meta-stable tetragonal gawo kupita ku gawo lokhazikika la monoclinic. Chifukwa cha ichi, mpweya umakula, kupangitsa kuti fracture iwonongeke ndikuwonjezera kulimba. Chifukwa cha kusiyana kwa momwe zopangira zidapangidwira, MSZ imatha kukhala minyanga yanjovu kapena yachikasu-lalanje mumtundu. MSZ, yomwe ili ndi mtundu wa minyanga ya njovu, ndi yoyera komanso ili ndi makina apamwamba kwambiri. M'malo otentha kwambiri (220 ° C ndi kupitilira apo) komanso chinyezi chambiri, MSZ imakhala yokhazikika kuposa YTZP, ndipo YTZP imatsitsa. Kupatula apo, MSZ ili ndi kutsika kwamafuta otsika ndi CTE yofanana ndi chitsulo choponyedwa, kuteteza kusagwirizana kwamafuta muzinthu za ceramic-to-zitsulo.
Katundu
Mkulu wamakina mphamvu
High fracture kulimba
Kukana kutentha kwakukulu
High kuvala kukana
Kukana kwakukulu
Kukana kwamphamvu kwamafuta
Otsika kwambiri matenthedwe madutsidwe
Kukula kwamafuta ndikoyenera kumisonkhano ya ceramic-to-metal
High chemical resistance (ma acid ndi maziko)
Mapulogalamu
Magnesia-stabilized zirconia amatha kugwiritsidwa ntchito m'mavavu, mapampu, ndi ma gaskets chifukwa amavala bwino komanso kukana dzimbiri. Ndiwonso chinthu chomwe chimakondedwa pamagawo a petrochemical ndi Chemical processing. Zirconia ceramics ndi njira yabwino pamagawo ambiri, kuphatikiza:
Zojambula za ceramic
Ma Bearings
Valani ziwalo
Valani manja
Utsi nozzles
Manja a pompo
Utsi pistons
Zomera
Zigawo zolimba za oxide cell cell
Zida za MWD
Maupangiri odzigudubuza opangira ma chubu
Zakuya bwino, downhole mbali
Magnesia-Stabilized Zirconia Machining
M'malo ake obiriwira, mabisiketi, kapena zowirira kwambiri, MSZ imatha kupangidwa. Ikakhala yobiriwira kapena ya bisiketi, imatha kupangidwa mwaluso kwambiri. Thupi la zirconia limachepa ndi pafupifupi 20% panthawi ya sintering, zomwe ndizofunikira kuti zisawonongeke mokwanira. Chifukwa cha kuchepa uku, zirconia pre-sintering sizingapangidwe ndi kulolerana kwabwino kwambiri. Zinthu zomwe zimasiyidwa bwino ziyenera kupangidwa ndi makina kapena kukulitsidwa ndi zida za diamondi kuti zisaloledwe kwambiri. M'njira yopangira izi, zinthuzo zimapukutidwa pogwiritsa ntchito chida chabwino kwambiri chokutidwa ndi diamondi kapena gudumu mpaka momwe zofunikirazo zitakwaniritsidwira. Izi zitha kukhala zowononga nthawi komanso zokwera mtengo chifukwa cha kuuma kwake komanso kuuma kwa zinthuzo.
