99.99% nano-alumina e tiileng ea ceramic
E ka sebelisoa bakeng sa li-ceramic tse sebetsang, li-ceramic tsa sebopeho, li-ceramic tse bonaletsang, le mechini ea masela.
1. Ka lebaka la superplasticity ea phofo ea nano-alumina, e rarolla mefokolo ea mefuta ea ts'ebeliso e lekanyelitsoeng ke ho brittleness ha mocheso o tlase. Har'a tsona, nanocomposites tsa nano-aluminium oxy-carbide (SiC) ke tsona tse hlahelletseng ka ho fetisisa, 'me matla a tsona a ho flexural a tsoa ho Li-ceramic tsa alumina tsa mohato o le mong li eketsehile ho tloha ho 300-400 MPa ho ea ho 1 GPa, 'me ho thiba ha thepa ho eketsehile ka ho feta 40%.
2. Ho tsitsa ha mocheso: Ho eketsoa ha nano-alumina ho substrate ea ceramic ha ho ntlafatse feela ts'ebetso ea ho sinter ea substrate, empa hape ho ntlafatsa haholo botsitso ba mocheso ba thepa ea substrate ea alumina, 'me botsitso ba mocheso bo ntlafala ka makhetlo a 2-3.
3. Botenya: Nakong ea ho bopa phofo e ntšang, phofo ea nano-α-Al2O3 e ka tlatsoa ka har'a masoba a phofo ea alumina ea micron, e leng se fokotsang boholo ba masoba; khatello ea ho bopa e ea eketseha, 'me palo ea masoba e ka fokotsoa, kahoo ea ntlafala. Botenya ba mahe a ceramic bo ntlafatsa botenya le thepa ea mechini ea li-ceramic tsa alumina ka mor'a ho sila.
4. Phokotso ea mocheso oa ho sila: ho eketsoa ha nano-a-Al2O3 ho khothalletsa ts'ebetso ea ho sila 'me ho thusa ho fokotsa mocheso oa ho sila. Ha mocheso oa ho sila o le 1450 °C, matla a ho kobeha le ho tiea ha ho robeha li fihla holimo.
5. Ho eketsa nano-a-Al2O3 e nyane ho ka ntlafatsa ka katleho thepa ea mechini ea thepa. Ceramic ea alumina e sintered ho 1450 °C. Ha palo ea ho eketsa e le 10%, matla a ho flexural ke 415 mPa mme ho tiea ha ho robeha ke 4.1 MPa·m^1. /2.
