Tšusumetso ea Mocheso oa Deposition Ho Zirconia Film Microstructure

ZrO2 e na le ntlha e qhibilihang haholo, e nang le mocheso o tlase oa mocheso, o tsoelang pele ka linako tsohle ka motlakase, o fetisang moea o phahameng oa ionic le botsitso bo phahameng ba lik'hemik'hale, 'me e sebelisoa haholo lifiliming tsa Optical, lifiliming tsa catalytic le lifiliming tsa mafura a oxide. ZrO2 e na le mekhahlelo e meraro ea kristale: monoclinic phase (M), tetragonal phase (T) le phase cubic (C). Ka hona, ZrO2 e tla fetoha ka mohato ka liphetoho tsa mocheso, e leng se tla fella ka phello e kholo ea molumo, 'me ts'ebetso ea motlakase ea ZrO2 e nyane,' me coefficient ea katoloso ea mocheso e kholo, e etsang hore ho hanyetsoa hoa mocheso oa ZrO2 e hloekileng ho futsanehe haholo, ka hona ho fokotsa ts'ebeliso ea ZrO2. Ho eketsa palo e nepahetseng ea li-oxide stabilizers ho ZrO2, tse kang Y2O3, MgO le CaO, li ka tsitsisa ZrO2 mohatong o phahameng oa mocheso. Har'a tsona, radius Y3 + (0.09nm) le Zr4 + radius (0.08nm), Y2O3 refractive index (1.9) le ZrO2 refractive index (2.0) li haufi haholo, ka hona, ho eketsoa ha Y2O3 ho ke ke ha baka phetoho e kholo mahalapeng a kamehla ZrO2 le index ea refractive. E tlase haholo, Y2O3 e tsitsitse filimi ea ZrO2 (YSZ) e bonts'a litšobotsi tse ntle tsa 'mele le lik'hemik'hale.

Ka hona, Y2O3 e sebelisetsoa ho tsitsisa ZrO2. Mekhoa ea ho itukisetsa filimi ea ZrO2 e kenyelletsa ho khohlela ha magnetron, ho kenya laser ea pulsed, mouoane oa elektrone, mouoane o thusitsoeng ke libone, jj. sebedisa. Ho makenete ea makenete, sekhahla sa phokotso ea liphofu tsa tšepe se makhetlo a 'maloa ho isa ho mashome a fetang a lipheo tsa kompone. Ka hona, liphofu tsa tšepe li sebelisoa khafetsa ho hlophisa lifilimi tsa ZrO2 le YSZ ts'ebelisong e sebetsang. Mocheso oa substrate o na le tšusumetso e kholo mohahong le ka holim'a morpholoji oa filimi e lokiselitsoeng ke ho qhoqha ho sa sebetseng. Ka hona, ho hlahloba tšusumetso ea mocheso oa phepelo mohahong o monyane oa lifilimi tsa ZrO2 le YSZ ho na le boleng ba bohlokoa ba ts'ebeliso. Leqepheng lena, mokhoa oa DC o sebetsang ka makenete oa magnetron o sebelisitsoe ho hlophisa lifilimi tse tšesaane tsa ZrO2 le yttrium oxidation e tsitsitseng e sebelisa "Zr target material" (bohloeki 99.999%, karoloana ea boima, e tšoanang ka tlase) le Y-Zr alloy target material (Y content 14.2mol %). Filimi ea Zirconium (YSZ), le tšusumetso ea mocheso oa substrate deposition (25 ℃ le 300 ℃) ho microstructure ea filimi ea ZrO2 le Y2O3 e tsitsitseng filimi ea ZrO2 e ile ea ithutoa.
