99.99% Ceramic toughened nano-alumina
Inogona kushandiswa pakugadzira zviumbwa zvesimbi, zviumbwa zvesimbi, zviumbwa zvesimbi zvinoonekera, uye michina yemachira.
1. Nekuda kwe superplasticity ye nano-alumina powder, inogadzirisa zvikanganiso zvekushandiswa kwemhando inoganhurirwa nekusasimba kwekupisa kwakaderera. Pakati pazvo, nano-aluminium oxy-carbide (SiC) nanocomposites ndidzo dzinonyanya kuzivikanwa, uye simba radzo rekuchinjika rinobva ku single-phase alumina ceramics yakawedzera kubva pa300-400 MPa kusvika pa1 GPa, uye kusimba kwekupwanyika kwezvinhu kwakawedzera neinopfuura 40%.
2. Kugadzikana kwekupisa: Kuwedzerwa kwe nano-alumina kune ceramic substrate hakungogadzirisi chete mashandiro ekupisa kwe substrate, asiwo kunovandudza zvikuru kugadzikana kwekupisa kwechinhu che alumina substrate, uye kugadzikana kwekupisa kunovandudzwa nekaviri kusvika katatu.
3. Kuwanda: Mukuita kwekugadzira upfu, upfu hwe nano-α-Al2O3 hunogona kuzadzwa mumaburi eupfu hwe micron alumina, izvo zvinoderedza saizi yemaburi; kumanikidzwa kwemuumbi kunowedzera, uye huwandu hwemaburi hunogona kuderedzwa, nokudaro zvichivandudzika. Kuwanda kwema embryo e ceramic kunovandudza kuwanda uye hunhu hwemakanika hwe alumina ceramics mushure mekupiswa.
4. Kudzikiswa kwekupisa kwekusvina: kuwedzerwa kwe nano-a-Al2O3 kunokurudzira basa rekusvina uye kunobatsira kuderedza tembiricha yekusvina. Kana tembiricha yekusvina iri 1450 °C, simba rekutenderera uye kusimba kwekupwanyika zvinosvika pakakwirira.
5. Kuwedzerwa kwehuwandu hushoma hwe nano-a-Al2O3 kunogona kuvandudza mashandiro emuchina wechinhu chacho. Alumina ceramic inopiswa pa1450 °C. Kana huwandu hwekuwedzera huri 10%, simba reflexural i415 mPa uye kuomarara kwekutyoka i4.1 MPa·m^1. /2.
