nanomita silicon carbide/ Nano SiC (SiC 40nm 99.9%)
Ngā āhuatanga matua oHe paura silicon carbide nanometer, he paura silicon carbide tino pai rawa atu i hangaia mā te tukanga motuhake me te parakore teitei, te whānuitanga tohatoha rahi matūriki iti, te horahanga mata motuhake teitei; he āhuatanga matū pumau te nano silicon carbide, he kawe wera teitei (165W/MK), he iti te tauwehenga o te whakawhānui wera, he pakeke teitei, he pakeke Mohs o te 9.5, he pakeke moroiti 2840 ~ 3320kg/mm2. Ko te tuatahi, ko ngā tāpiringa kakahu o ngā rauemi, ko tōna pakeke i waenga i te corundum me te taimana, ko te kaha miihini he teitei ake i te corundum; he pai te kawe wera o te nano silicon carbide, he semiconductor rānei, he ārai-waikura pāmahana teitei; he ātete kakahu te nano silicon carbide, he ātete pāmahana teitei, he waikura, he waikawa me te kawakore, he whānuitia te whakamahinga i roto i ngā peita, peita o roto, ka whakanui ake i te ātete kakahu.
1. He rauemi nairona kaha-teitei kua whakarerekētia: he pai te hototahi o te paura nano-SiC i roto i ngā hiato polymer, he pai te marara, ā, ko te papa, ko te kaha kume koranu nairona kaha-teitei kua whakarerekētia kua piki ake i te PA6 noa mā te 150%, ā, neke atu i te toru ngā wā kua piki ake te ātete kakahu. Ko te nuinga e whakamahia ana mō ngā waka arai pukupuku, ngā wāhanga polymer, ngā wāhanga urungi, ngā mīhini kakahu, ngā mīhini keri, ngā arai, ngā wāhanga tereina ka taea te whakatutuki i te whakamaroketanga sintering i te pāmahana iti iho;
2. Te whakarerekētanga o te ātete kakahu o te kirihou hangarau motuhake me te polyether ether ketone (PEEK): i muri i te maimoatanga mata nano silicon carbide, tāpirihia te 5% pea, ka taea te whakapai ake me te whakarei ake i te ātete kakahu o PEEK me te (ki te whakapai ake i te taketake neke atu i te 30%);
3. Te kāpira silicon nm i roto i te potae rapa: te tāpiri i te kāpira silicon nano ki raro i te kaupapa, tata ki te 2%, kāore e whakarerekē i te tauira kāpia taketake, me te kore e whakararu i tana mahi taketake me te kounga, ka taea te whakanui ake i te ātete kakahu mā te 20% -40%. Hei tāpiri, ko te kāpira silicon 40 nm e whakamahia ana i roto i te roera rapa, te kiriata whakakī pūreretā, te wera, te pāmahana me ētahi atu hua rapa;
4. paninga hiato nano-SiC mata whakarewa: he matūriki whakaranu o ngā matūriki nanoscale, he konganuku nickel matrix, ka hangaia he mata whakarewa he kiato teitei, he pai te here o te paninga hiato electrodeposited, he tino pakeke te mata whakarewa (kakahu) me te āhuatanga pāmahana teitei e whakahinuhinu ana i a ia anō. Ka tino whakapai ake te pakeketanga moroiti o te paninga hiato, ka piki ake te ātete kakahu mā te 2-3 ngā wā, ka piki ake te roa o te ratonga mā te 3-5 ngā wā, ka piki ake te kaha here o te paninga me te papa ki te 40%, ka taea te hipoki, ka rite te paninga, ka maeneene, ka taipitopito; E rima atu ngā tono: uku hanganga mahi-teitei (pēnei i ngā pūwero rōkete, te umanga karihi, me ētahi atu), ngā mimiti, te hinu ārai-kakahu, ngā papa parai mahi-teitei, te paninga paura pakeke me te ātete-kakahu, te whakapakari me te whakapakeke i te hiato uku;
te hanganga o te umanga rererangi o te paninga, te paninga mahi, te paninga tiaki, ngā rauemi mimiti, ngā rauemi huna, me ētahi atu;
te pukupuku tiaki o ngā tāke me ngā waka pukupuku; mō ngā taputapu tapahi uku, ngā taputapu tapahi, ngā taputapu ine, ngā pokepokea ai;
ka taea te whakamahi mō ngā kaupapa motuhake o ngā uku hanganga, ngā uku mahi, ngā uku hangarau; te mura; ngā wāhanga whakamahana hiko mō te whakamahinga ahumahi, te whakaputa hiko infrared tawhiti.
