Silicon Carbide Whisker

Silicon carbide whisker(SiC-w) zvinhu zvitsva zvakakosha zvehunyanzvi hwepamusoro.Ivo vanosimbisa kuomarara kwezvinhu zvepamberi zvakaumbwa sesimbi base composites, ceramic base composites uye yakakwirira polymer base composites.Zvakare yakashandiswa zvakanyanya mukugadzirwa kweceramic yekucheka maturusi, space shuttles, zvikamu zvemotokari, makemikari, michina uye simba.

SiC ndebvu parizvino inoshandiswa mukuomesera maturusi eceramic.IUnited States yakabudirira kugadzira "SiC whiskers uye nano composite coatings" yekupfeka-kusapfeka, inodzivirira corrosion uye yakakwirira-tembiricha coatings.Iko kudiwa kwemusika weSiC ndebvu kuchawedzera zvakanyanya uye tarisiro yemusika yakakura kwazvo.

Silicon carbide whiskers ine yakanakisa mechaniki zvivakwa, kupisa kupisa, corrosion resistance, uye yakanyanya tembiricha oxidation kuramba.Chigadzirwa chitsva ichi chine kuenderana kwakanaka nezvinhu zvematrix uye chave chikuru chekusimudzira uye chinoomesera mumiriri wemhando dzakasiyana dzemhando yepamusoro inoumba zvinhu mumakore achangopfuura.Inoshandiswa zvakanyanya sesimbi, plastiki, ceramic composite zvinhu.Iyo silicon carbide whisker-yakasimbiswa macomposites inogona kugadzirwa kuti ishandiswe mune aerospace, mauto, migodhi uye simbi, indasitiri yemakemikari, mota, midziyo yemitambo, maturusi ekucheka, nozzles, uye yakanyanya-tembiricha inodzivirira.Iyo whisker-yakasimbiswa silicon nitride ceramic matrix composite zvinhu ine yakanakisa yemuviri uye michina zvivakwa, uye inogona kushandiswa zvakanyanya mukusiyana-siyana kupfeka-yekudzivirira, yakakwirira-yekushisa inodzivirira, isingadziviriri, uye inodzivirira-inodzivirira zviitiko mukuwedzera kune zvikamu zveinjini. uye ane tarisiro yakafara..Mumaturusi ekucheka, masaha ematombo, machira ekucheka, majecha ejecha, tembiricha extrusion inofa, mhete dzekuisa chisimbiso, nhumbi dzokurwa, nezvimwewo zvine kudiwa kukuru kwemusika.

SIC Whisker, Silicon Carbide Whisker, SiC Nanowire Mugadziri

Musika wezvigadzirwa zveceramics kuNorth America unosanganisira kunyanya kucheka maturusi, zvipfeko zvekupfeka, zvikamu zveinjini yekupisa uye zvigadzirwa zvetekinoroji.Inenge 37% yezvimiro zveceramic zvikamu zvinogadzirwa neceramic matrix composite.Izvo zvasara ndechimwe chete ceramic chigadzirwa.Ceramic matrix macomposites anonyanya kushandiswa mukugadzira maturusi ekucheka, kupfeka zvikamu, kuisa, uye zvigadzirwa zvemuchadenga.Yechishandiso chekucheka, yakawanda yemusika wechigadzirwa (inenge 41%) inogadzirwa uchishandisa matrix composite ceramic matrix composite yakagadzirwa neTiC, yakasimbiswa Si3N4 uye Al2O3, uye Al2O3 yakasimbiswa neSiC ndebvu chigadzirwa chinopfeka, mamwe marudzi Ceramic composites zvakare. inoshandiswa mu radar, injini uye ndege gasi turbines.17% yezvigadzirwa zveceramics zvinoshandiswa kune maturusi eceramic.Kusanganisira Al2O3, Al2O3/TiC, SiC whisker yakasimbisa Al2O3, Si3N4 uye Sialon ceramics.Iko kumhanyisa kwekusimudzira kwemusika weceramic chishandiso kwakabatsirikana kubva mukukwidziridza kwemaindasitiri.Kudzikiswa kweSiC whisker-yakakwidziridzwa Al2O3 uye Si3N4 maturusi mitengo inoitawo kuti maturusi e ceramic awedzere kukwikwidza mumusika.
