I-Silicon Carbide Whisker

I-silicon carbide whisker(SiC-w) yizinto ezintsha ezibalulekile zobuchwepheshe obuphezulu. Ziqinisa ukuqina kwezinto ezihlanganisiwe ezithuthukisiwe njengezinhlanganisela zesisekelo sensimbi, izinhlanganisela zesisekelo se-ceramic kanye nezinhlanganisela zesisekelo se-polymer ephezulu. Futhi isetshenziswe kabanzi ekukhiqizeni amathuluzi okusika i-ceramic, izithuthuthu zasemkhathini, izingxenye zezimoto, amakhemikhali, imishini namandla.

Njengamanje amadevu e-SiC asetshenziswa kumathuluzi obumba aqinile. I-United States ithuthukise ngempumelelo "amadevu e-SiC kanye ne-nano composite coatings" yezingubo ezingagqoki, ezimelana nokugqwala kanye nezinga lokushisa eliphezulu. Isidingo semakethe samadevu e-SiC sizokhuphuka kakhulu futhi ithemba lemakethe libanzi kakhulu.

Amadevu e-silicon carbide anezakhiwo ezinhle kakhulu zemishini, ukumelana nokushisa, ukumelana nokugqwala, kanye nokumelana ne-oxidation ephezulu lokushisa. Umkhiqizo omusha unokuhambisana okuhle nezinto ezisetshenziswayo ze-matrix futhi usuphenduke i-ejenti ethuthukisa kakhulu neqinisayo ezinhlotsheni ezahlukahlukene zezinto ezihlanganisiwe ezisebenza kahle eminyakeni yamuva nje. Isetshenziswa kabanzi njengensimbi, ipulasitiki, izinto ezihlanganisiwe ze-ceramic. Izinhlanganisela ze-silicon carbide whisker-reinforced zingathuthukiswa ukuze zisetshenziswe ku-aerospace, amasosha, izimayini kanye ne-metallurgy, imboni yamakhemikhali, izimoto, imishini yezemidlalo, amathuluzi okusika, ama-nozzles, nezingxenye eziphikisana nokushisa okuphezulu. Izinto ezihlanganisiwe ze-silicon nitride ceramic matrix eziqiniswe nge-whisker zinezakhiwo ezinhle kakhulu zomzimba nezomshini, futhi zingasetshenziswa kabanzi ezikhathini ezihlukahlukene ezingagugi, ezimelana nokushisa okuphezulu, ukumelana nokugqwala, kanye nezikhathi ezingabambeki ngaphezu kwezingxenye zenjini, futhi inamathemba abanzi. . Emathuluzini okusika, amasaha amatshe, abasiki bendwangu, imibhobho ye-sandblasting, ukushisa okuphezulu kwe-extrusion kufa, izindandatho zokuvala, izikhali, njll. kunesidingo esikhulu semakethe.

I-SIC Whisker, i-Silicon Carbide Whisker, i-SiC Nanowire Manufacturer

Imakethe ye-ceramics yesakhiwo eNyakatho Melika iqukethe ikakhulukazi amathuluzi okusika, izingxenye zokugqoka, izingxenye zenjini yokushisa kanye nemikhiqizo yobuchwepheshe be-aerospace. Cishe i-37% yezingxenye ze-ceramic zesakhiwo zenziwe ngezinhlanganisela ze-ceramic matrix. Okusele kungumkhiqizo owodwa we-ceramic. Izinhlanganisela ze-Ceramic matrix zisetshenziswa kakhulu ekukhiqizeni amathuluzi okusika, izingxenye zokugqoka, okokufaka, kanye nemikhiqizo ye-aerospace. Ngethuluzi lokusika, iningi lemakethe yomkhiqizo (cishe i-41%) ekhiqizwa kusetshenziswa inhlanganisela ye-matrix ehlanganisiwe ye-ceramic matrix eyenziwe nge-TiC, i-Si3N4 eqinisiwe ne-Al2O3, futhi i-Al2O3 eqiniswe ngentshebe ye-SiC ingumkhiqizo ongagugi, ezinye izinhlobo ze-Ceramic composite nazo. esetshenziswa ku-radar, injini kanye nezinjini zegesi zezindiza. I-17% ye-ceramics yesakhiwo isetshenziswa kumathuluzi e-ceramic. Kubandakanya i-Al2O3, i-Al2O3/TiC, i-whisker ye-SiC eqinisiwe i-Al2O3, i-Si3N4 ne-Sialon ceramics. Isivinini sokuthuthukiswa kwemakethe yamathuluzi e-ceramic sizuze ekusheshisweni kwezimboni. Ukwehliswa kwezintengo zamathuluzi ezithuthukisiwe ze-SiC Al2O3 kanye ne-Si3N4 nakho kwenza amathuluzi e-ceramic aqhudelane kakhulu emakethe.
