Isu tinopa kuchena kwakanyanya kweNano Silicon carbide poda. Rongedza chikamu alloy zvigadzirwa zvinoenderana nezvinodiwa nemutengi.

Main maitiro

Ultrafine nano silicon carbide, silicon carbide powder by variable current laser ion beam, chemical vapor deposition by variable current, high voltage discharge, inogona kukurira zvakakwana kukanganisa kwe dc electric arc (kupindura kusina kukwana, kusvibiswa kwepamusoro kwechigadzirwa, kusagadzikana kwezvigadzirwa).Kuchena kwepamusoro, kugovera saizi diki, yakakwirira chaiyo nzvimbo;Nano silicon carbide ine kugadzikana kwemakemikari kuita, yakakwira coefficient yekupisa conductivity (165 w/MK), diki yekupisa yekuwedzera coefficient, kuomarara kwakanyanya, mohs kuomarara kusvika pa9.5, iyo microhardness ye2840 ~ 3320 kg/ndiyo yaive yekutanga zvinhu zvinodzivirira abrasion. kuoma kwayo kuri pakati pealuminium yakasanganiswa nedhaimani, simba remuchina rakakwirira kudarika aluminium yakasanganiswa;Nano silicon carbide ine yakanakisa thermal conductivity, iriwo rudzi rwe semiconductor, inogona pakupisa tembiricha oxidation kuramba;Nano silicon carbide kupfeka-resisting, yakakwirira tembiricha kuramba, corrosion resistance, kuramba kune acid uye alkali solvent, inoshandiswa zvakanyanya mupende, pendi, inowedzera kusapfeka.

Apllication

1 yakagadziridzwa yakakwira simba naironi zvinhu: nanometer SiC hupfu mupolymer inoumbwa nezvinhu inoenderana yakanaka, yakanaka dispersibility, uye yakasanganiswa neakanaka matrix, uye yakagadziridzwa naironi alloy yakasimba kusimba kwesimba nekupfuura 150% yakakwirira kupfuura iyo yakajairwa PA6, kupfeka- kuramba kuita kwakawedzera nekanopfuura katatu.Kunyanya kune yakarongedzerwa yakarongedzerwa mota polymer zvikamu, mota inotungamira zvikamu, machira emuchina, migodhi muchina lining board, zvikamu zvechitima pasi peyakadzika tembiricha sintering densification inosvika;

2 yakagadziridzwa yakakosha engineering mapurasitiki polyether ether ketone (PEEK) kupfeka-kuramba kuita: mushure mekugadzirisa pamusoro penano silicon carbide, kana kuwedzera huwandu hunenge 5%, inogona kuvandudza zvakanyanya nekusimudza kupfeka kwePEEK (yakawedzera neinopfuura 30% );

3 yekushandiswa kwenano silicon carbide muvhiri rerabha: kuwedzera 2% kana zvakadaro ye nano silicon carbide pasina kushandura collagen yakagadziridzwa fomula, uye pasina kudzikisa kuita kwayo uye kunaka pasi pechikonzero chekupfeka kwayo kuramba kunogona kuwedzera ne20% - 40. %.Uye zvakare, kushandiswa kwenano silicon carbide murubha roller, iyo printer fuser firimu, senge kupfeka kuramba, kupisa, kupisa kupisa uye zvimwe zvigadzirwa zverabha;

4 nanometer SiC composite coating metal surface: iyo nano-scale particles yechipiri hybrid particles, nickel sesimbi yematrix, iyo simbi yepasi kuti igadzire yakakwira density, simba rekubatanidza rakanaka kwazvo composite electrodeposition, iyo simbi yepasi ine yakaoma (kupfeka) uye antifriction ( self-lubricating) yakakwirira tembiricha inodzivirira maitiro.Kuvandudza zvakanyanya iyo composite coating microhardness, kupfeka kuramba kunowedzera 2-3 nguva, kunatsiridza hupenyu hwesevhisi ye3-5 nguva, kusimba kwekunamatira kwekuputira uye substrate yakawedzera ne40%, yekuvharira kugona kwakasimba, yunifomu yekupfeka, yakatsetseka uye yakapfava;

5 mamwe maapplication: yakakwira dhizaini dhizaini (senge rocket nozzle, iyo indasitiri yenyukireya, nezvimwewo), zvinhu zvinotora, kupfeka-inodzivirira mafuta ekuzora, yakakwirira-inoshanda mabhureki mapedhi, kuoma kwakanyanya, kupfeka kuramba kwehupfu, composite ceramic inosimudzira kuomarara. , nezvimwewo;Mumunda weaerospace indasitiri chimiro, inoshanda coating, inodzivirira yekudzivirira, coating inonwisa zvinhu, stealth materials, etc .;Matangi nemotokari dzine zvombo zvekudzivirira;Yeceramic yekucheka mudziyo, yekucheka chishandiso uye yekuyeresa chishandiso uye kufa;Sekushandiswa kwakakosha zvimiro zvekeramics, inoshanda ceramics, engineering ceramics;Ignition;Magetsi maindasitiri emagetsi ekudziya zvinhu, kure infrared jenareta.
