Silicon Carbide Whisker

Silicon carbide whisker(SiC-w) yog cov ntaub ntawv tshiab tseem ceeb rau kev siv tshuab siab.Lawv ntxiv dag zog rau cov ntaub ntawv zoo tshaj plaws xws li hlau puag sib xyaw, ceramic puag composites thiab siab polymer puag composites.Tsis tas li ntawd nws tau siv dav hauv kev tsim cov cuab yeej ceramic, chaw shuttles, tsheb qhov chaw, tshuaj, tshuab thiab lub zog.

SiC whiskers yog tam sim no siv nyob rau hauv toughening ceramic cov cuab yeej.Tebchaws Asmeskas tau ua tiav "SiC whiskers thiab nano composite coatings" rau hnav-resistant, corrosion-resistant thiab high-temperature coatings.Kev ua lag luam xav tau rau SiC whiskers yuav nce siab thiab kev cia siab ntawm kev lag luam yog dav heev.

Silicon carbide whiskers muaj cov khoom siv zoo heev, ua haujlwm kub, tiv thaiv corrosion, thiab kub oxidation kuj.Cov khoom tshiab muaj kev sib raug zoo nrog cov ntaub ntawv matrix thiab tau dhau los ua ib qho kev txhim kho loj thiab tawv tawv rau ntau hom kev ua tau zoo ntawm cov ntaub ntawv sib xyaw hauv xyoo tas los.Dav siv los ua hlau, yas, cov khoom siv ceramic.Lub silicon carbide whisker-reinforced composites tuaj yeem tsim rau kev siv hauv aerospace, tub rog, mining thiab metallurgy, tshuaj lom neeg kev lag luam, tsheb, khoom siv ua kis las, cov cuab yeej txiav, nozzles, thiab cov khoom kub-resistant.Cov khoom siv dag zog siv silicon nitride ceramic matrix muaj cov khoom siv zoo heev ntawm lub cev thiab cov khoom siv kho tshuab, thiab tuaj yeem siv dav hauv ntau yam hnav-tiv taus, kub-resistant, corrosion-resistant, thiab feem-resistant zaus ntxiv rau qhov chaw ntawm lub cav, thiab muaj kev cia siab dav..Hauv cov cuab yeej txiav, pob zeb saws, textile cutters, sandblasting nozzles, kub extrusion tuag, sealing rings, armor, thiab lwm yam. muaj kev lag luam zoo heev.
