nano-titanium carbide hmoov / nano TiC 40nm 99.9%
Cov yam ntxwv tseem ceeb ntawm nano-titanium carbide, ultra-fine titanium carbide hmoov npaj los ntawm txoj kev tshwj xeeb, purity siab, me me particle loj faib ntau yam, siab tshwj xeeb nto cheeb tsam, siab nto kev ua ub no, siab kub, anti-oxidation, yog ib tug zoo refractory-resistant sib tsoo khoom, yog dav siv rau carbide, hnav superhard cov ntaub ntawv saum toj no; titanium carbide lub melting point ntawm txog 32 ℃, carbide Cheebtsam, nrog siab hardness, corrosion tsis kam, zoo thermal stability, siv nyob rau hauv kev tsim cov khoom hnav-resistant, txiav cov cuab yeej, pwm, melting hlau crucibles thiab lwm qhov chaw; vim hais tias cov me me particle loj thiab yog li ntawd muaj siab nto kev ua ub no, nrog zoo hluav taws xob conductivity, tshuaj inertness, thiab zoo heev kev ua tau zoo nrog rau hlau thiab hlau hlau; ntxiv kaum txhiab ntawm nano-titanium carbide tuaj yeem txo titanium carbide ceramic sintering kub ntawm 200 degrees, thiab tuaj yeem refined ceramic nplej thiab txhim kho cov ceramic sintering txheej txheem; nano-titanium carbide ua ib tug ceramic khoom siv reinforced los txhim kho cov khoom siv kho tshuab ntawm hlau, ceramic matrix khoom thiab conductive khoom.
1. nm titanium carbide siv rau hauv cov khoom siv aerospace: coj mus rau hauv tus account refractory nano-carbides TiC ntawm ZrC muaj lub melting point saum 3000 ℃, nrog lub zog kub zoo, thiab kev sib raug zoo nrog tungsten, zoo sib xws coefficient ntawm thermal expansion, thiab muaj ntau dua li tungsten ntawm qhov ceev qis dua. Nano ntawm TiCp / w thiab ZrCp / w composite lub zog nrog nce kub maj mam nce. Nano ntawm TiCp / w thiab ZrCp / w ntawm 1000 ℃ thiab 800 ℃ feem, lub zog siab tshaj plaws tau nce ntau piv rau qhov muaj zog ntawm chav tsev kub. Tom qab ntawd qhov kub txuas ntxiv mus, qhov muaj zog txo qis. Composites ntawm qhov kub siab no txawv txawv, W lub hauv paus lub cev nrog qhov kub thiab txias los txhim kho brittleness hloov pauv rau cov yas, ua rau cov nano-TiC thiab ZrC cov khoom ntawm qhov kub siab yas W-raws li lub cev lub luag haujlwm txhim kho txawm tias tseem ceeb dua nrog, ua rau muaj lub zog kub zoo heev ntawm cov khoom sib xyaw nano-TiC cov khoom NONSTOICHIOMETRIC NANO ZrC cov khoom W substrate muaj qhov kub zoo dua;
2. nm titanium carbide ceramic ua npuas ncauj: ua npuas ncauj ua los ntawm cov khoom siv ceramic ua lub lim dej hauv cov kua dej tuaj yeem tshem tawm tau zoo, lub tshuab lim dej yog do thiab adsorption. Lub lim dej xav tau cov khoom siv tshuaj lom neeg ruaj khov, tshwj xeeb tshaj yog nyob rau hauv kev lag luam metallurgical yog siv cov lim dej xav tau ntawm qhov siab melting point, thiab yog li ntawd feem ntau ntawm cov khoom siv zoo li no rau oxide, thiab hloov kho rau kev lim dej ntawm cov hlau yaj, feem ntau yog kev nrhiav kev txhim kho ntawm kev tiv thaiv thermal poob siab. Nano titanium carbide ceramic ua npuas ncauj muaj lub zog siab dua, tawv, thermal conductivity, hluav taws xob conductivity, thiab cua sov thiab corrosion tsis kam dua li oxide ceramic ua npuas ncauj; Siv dav hauv kev tsim cov khoom siv hnav-resistant hauv ntau qhov chaw ntawm cov cuab yeej txiav, pwm, melting hlau crucibles thiab lwm yam pob tshab titanium carbide ceramics thiab cov ntaub ntawv kho qhov muag; titanium carbide abrasive ntawm abrasives thiab abrasive kev lag luam yog lwm txoj hauv kev rau txhuas oxide, silicon carbide, boron carbide, ib qho khoom zoo tagnrho ntawm chromium oxide thiab lwm yam khoom siv abrasive ib txwm muaj; nano-titanium carbide sib tsoo sib piv nrog cov pob zeb diamond hluavtaws, txo cov nqi hauv Tebchaws Meskas, Nyiv, Russia thiab lwm lub tebchaws tau siv dav. Cov ntaub ntawv Nano titanium carbide, abrasives, sib tsoo log thiab sib tsoo tshuaj pleev cov khoom tuaj yeem txhim kho qhov kev sib tsoo zoo heev, thiab txhim kho qhov tseeb ntawm kev sib tsoo thiab qhov chaw tiav.
4. thaj chaw ntawm hmoov metallurgy: Nano-titanium carbide hmoov rau hmoov metallurgy ntau lawm ntawm ceramics, carbide qhov chaw ntawm cov khoom siv raw, xws li hlau kos duab tuag, carbide tuag thiab lwm yam. Nano titanium carbide raws li cemented carbide muaj cov yam ntxwv hauv qab no: (1) siab hardness, feem ntau mus txog HRA90 saum toj no; (2) hnav tsis kam, qis hnav tus nqi; (3) kub siab thiab antioxidant peev xwm; (4) zoo thermal conductivity, zoo tshuaj stability.
