Silicon carbide whisker

Silicon carbide whisker(SIC-w) ndiyo kiyi mitsva midziyo yehunyanzvi hombe. Ivo vanosimbisa kutyisidzira kweyakafambira mberi manyoro eyakagadzirwa senge simbi base manyoro, ceramic base comosites uye yakakwirira polymer base base. Zvakare zvakare inoshandiswa zvakanyanya mukugadzirwa kwemidziyo yekucheka cutret, nzvimbo yekuvhara, zvikamu zvemotokari, makemikari, michina uye simba.

Sic whiskers parizvino inoshandiswa mukukoshesa ceramic maturusi. United States yakabudirira kukudziridza "sic whiskers uye nano composite yejasi" yekupfeka-inodzivirira, inodzivirira, yekudzivirira uye yakanyanya kupisa uye yakanyanya kupisa. Iyo musika inoda kuti vimbi yeSIC ichawedzera zvakanyanya uye tarisiro yemusika iri yakafara kwazvo.

Silicon carbide yehembe dzakanakisa dzine midziyo yekuzvidzivirira, kupisa kupesana, kurwisa, uye nekudziya kwekushisa kurwisa. Chigadzirwa chitsva chine kuwirirana kwakanaka nemakiromita uye kwakava kusimudzira kukuru uye kusimudzira mumiririri emhando dzakasiyana siyana dzezvakawanda zvekuita zvigadzirwa mumakore apfuura. Inoshandiswa zvakanyanya simbi, epurasitiki, ceramic composite zvigadzirwa. Silicon carbide manyorerwe-yakasimbiswa-yakasimbiswa mari yekunyorera muEerospace, mauto, mitallurgy, yemitambo, midziyo yemitambo, midziyo yekucheka, uye nzvimbo dzekupenga, uye dzakakura dzekudzivirira. Whither-yakasimbiswa Silicon Nitride Ceramic Mazita ekuumbwa ane zvinhu zvakaringana uye zvichikwira zvakanyanya, zvinodzivirira, zvinodzivirira, uye zvinokanganisa nguva dzekuwedzera kweinjini, uye ine tarisiro yakakura. . Mukucheka maturusi, matombo ematombo, machira emachira, sandble boxical nozzles, inosimbisa mhete, chombo, etc. kuva nemusika wekuda.

Sic whisker, silicon carbide whisker, sic nanowire mugadziri

Mishonga yeCeramics yeCondics kuNorth America inowanzoita zvishandiso zvekucheka, kupfeka zvikamu, kupisa injini zvikamu uye Aerospace tekinoroji zvigadzirwa. About 37% yezvimiro zveCeramic zvikamu zvakagadzirwa neCeramic matrix mapoka. Iyo yakasara ndeye imwe ceramic chigadzirwa. Ceramic Matrix manyadzo inonyanya kushandiswa mukugadzirwa kwekucheka maturusi, kupfeka zvikamu, zvinopenya, uye zvigadzirwa zvezvivakwa. Kune chishandiso chekucheka, mazhinji emusika wechigadzirwa (anenge 41%) akagadzirwa achishandisa matrix ceramic 17% yezvemamiriro emagetsi anoiswa kumatombo eCeramic. Kusanganisira Al2o3, Al2o3 / Tic, Tic whisker yakasimbiswa al2o3, Si3n4 uye Sialon Ceramics. Kumhanya kwekuvandudza kweiyo ceramic mudziyo weColam Market kwakabatsirwa nekuwedzera kwekushanda. Kuderedzwa kweSIC whisker-inosimbisa al2o3 uye Si3n4 Mitengo yeMitengo inogadzira zvakare zvishandiso zvemakwikwi mumusika.
