ZTA (Zirconia Toughened Alumina) ceramic rabber vulcanized plate chigadzirwa chinodzivirira kupfekwa chakagadzirwa zvakananga kuti chigadziriswe mumamiriro ekukwesha zvakanyanya. Chigadzirwa ichi chinobatanidza ZTA ceramics (inowanzo gadzirwa ne75%-80% Al₂O₃ uye 20%-25% ZrO₂) nerabha yechisikigo ine elasticity yakakwira uye simbi inodzosera simbi kuburikidza nemaitiro epamusoro e vulcanization, ine mabhaudhi akasungirirwa kare kuti zvive nyore kuisa. Pfungwa huru yekugadzira inoshandisa kuramba kupfekwa kwakanyanya kweceramics kuti itsungirire kukwesha kwezvinhu ukuwo rabha ichitora simba rekukwesha, zvichiita kuti pave nekubatana pakati pekudzivirira kupfekwa nekusimba kwekukwesha.
Nekuda kwekuchinja kwechikamu chezirconia, ZTA inoratidza kusimba kwakanyanya kwekupwanyika uye kuramba kupfeka kupfuura zviumbwa zve alumina zvemazuva ano. Tsvagiridzo inoratidza kuti zviumbwa zve ZTA zvine 20%-25% zirconia zvinoratidza kushanda zvakanaka mumamiriro ezvinhu akaomarara ekukuvadzwa. Maitiro akajairika ehunyanzvi anosanganisira: kuwanda kwehuwandu ≥4.1-4.3 g/cm³, kuomarara kweRockwell (HRA) ≥90, kuomarara kwekupwanyika (KIC) ≥3.70 MPa·m1/2, uye simba reflexural >350 MPa. Mukuyedzwa kwekukweva kwakapfava, mwero wekukweva chaiwo weZTA composites unogona kunge wakaderera se10⁻⁹ mm³/(N·m), unoshanda zvakanyanya kupfuura zviumbwa zve alumina kana zirconia zve single-phase.
Maitiro ekugadzira anosanganisira kupisa kunodzorwa nemazvo kuti pave nechokwadi chekuti simba rekubatanidza rakakwirira pa ceramic-rabber interface. Zvichienderana nezvinodiwa neindasitiri, simba rekubatanidza rabha pakati pe ceramic nerabha rinofanira kupfuura 3.5 MPa, rabha yacho pachayo ichiratidza simba rekudhonza re12-15 MPa uye kureba pakuputsika kuri kupfuura 250%-400%. Chimiro che vulcanized composite chinodzivirira mataira e ceramic kuti asabve pakuputsika, ukuwo kuchinja kwerabha kuchiparadzira kushushikana kwakasimba, kuchidzivirira ceramic layer kubva pakuputsika. Plate yekumashure yesimbi inoita kuti chimiro chive chakasimba kana chakaiswa pamasherufu emidziyo.
Mahwendefa eZTA ceramic rabha akaputirwaAnonyanya kushandiswa mumachute ekuchinjisa, mahopper, uye mabhini emasisitimu ekubata zvinhu zvakawanda uko kukanganiswa nekukweshwa kwakawanda. Kana tichienzanisa nemapurasitiki epurasitiki e-alumina ceramic, ZTA inopa hupenyu hwebasa hwakareba kanopfuura kaviri nehafu pasi pemamiriro ekukweshwa, nepo mutengo wayo uchiramba wakaderera zvakanyanya pane maceramics e-zirconia ceramics, zvichipa kushanda kwakanaka kwazvo. Kune mashandisirwo ekubata zvinhu zvakakura, kureba kwakakwirira, kana kumhanya kwakanyanya kwekuyerera, mapurati e-ZTA rabha anomiririra imwe yemhinduro dzekudzivirira kupfeka dzakavimbika dziripo.
