Density Measurement
Dhata kubva papycnometer yezviyero zve density pane pristine sample (Brass neZirconia) nemasampuli akashatiswa anochengetwa pa300 °C uye 600 °C.
Masamples eceramic akachengetedza chiyero chakafanana chekuwanda kwezvakapfava uye zvakadzikiswa (300 °C uye 600 °C) sampuli.Aya maitiro anotarisirwa neZirconia nekuda kweiyo electrovalent bonding yezvinhu zvinokweretesa kumakemikari ayo uye kugadzikana kwechimiro.
Zirconia based materials inoonekwa semamwe akanyanya kugadzikana oxides uye yakatoratidzwa kuti zvishoma nezvishoma inoora patembiricha yakakwira pedyo ne1700 ° C.Naizvozvo, kushandisa iyo ceramic centerpost kune yakanyanya kupisa tembiricha inogona kuve sarudzo yekuchenjera, kunyangwe kuumbwa kweiyo sintered.

■Mufananidzo 3
Rutivi rwekuruboshwe runoratidza simbi sampuli dzepristine uye 600 ° C uye kurudyi kunoratidza ceramic pristine uye 600 ° C.
Mufananidzo wechitatu unoratidza iyo yepamusoro-resolution imaging yeakakwenenzverwa uye akamisikidzwa pristine uye yakaderedzwa samples.Sezvazvinogona kuonekwa, hapana humbowo hwekuparara mumasampunzi eceramic (kuruoko rwerudyi mifananidzo).Iwo masampula ane chimiro chakafanana chemuviri icho chinokweretesa kugadzikana kweiyo ceramic sampu pakupisa kwakanyanya.Kune rumwe rutivi tinoona shanduko yakanyanyisa mumorphology yepasi pamasampuli endarira akaderedzwa.Kumusoro kwesampu yendarira kwakaderedzwa kuratidza kunorema oxidation.Kuumbwa kwemuviri kweiyo oxide layer ingangove yakakonzerawo shanduko mukuwanda kwesampu yebrass.
