Cov lus nug txog CCov ntaub ntawv zoo sib xwsthiab tungsten carbide

Cov ntaub ntawv sib xyaw yog cov ntaub ntawv tseem ceeb hauv engineering vim lawv cov khoom siv kho tshuab zoo heev. Composites yog cov ntaub ntawv uas xav tau cov khoom ntawm cov khoom sib cais los ntawm kev sib koom ua ke los ntawm kev sib koom ua ke. Txhua yam ntawm cov khoom khaws nws cov qauv thiab cov yam ntxwv, tab sis cov khoom sib xyaw feem ntau muaj cov khoom zoo dua. Cov ntaub ntawv sib xyaw muab cov khoom zoo tshaj plaws rau cov pa roj carbon monoxide rau ntau yam kev siv vim lawv muaj qhov tawv tawv, lub zog thiab hnav tsis kam.

Txoj kev loj hlob ntawm cov ntaub ntawv no pib nrog kev tsim cov khoom siv txuas ntxiv-fiber-reinforced composites. Tus nqi siab thiab nyuaj ntawm kev ua cov khoom sib xyaw no txwv tsis pub lawv daim ntawv thov thiab ua rau kev txhim kho ntawm cov khoom sib txuas ntxiv tsis tu ncua. Lub hom phiaj koom nrog hauv kev tsim cov khoom siv hlau matrix sib xyaw yog los ua ke cov khoom tsim nyog ntawm cov hlau thiab ceramics.

Txawm hais tias hu ua cov hlau tawv, Tungsten Carbide yog cov khoom siv sib xyaw nrog cov khoom tawv tawv ntawm tungsten Carbide embedded nyob rau hauv lub softer matrix ntawm hlau Cobalt.

Vim li cas cov composites muaj zog heevth?

Composites tau tsim los ntawm ib daim ntawv ntawm cov pa roj carbon hu ua graphene ua ke nrog cov hlau tooj liab, tsim cov khoom siv 500 npaug zog dua tooj liab ntawm nws tus kheej. Ib yam li ntawd, ib qho kev sib xyaw ntawm graphene thiab npib tsib xee muaj zog ntau dua 180 npaug ntawm npib tsib xee. Raws li rau fiberglass, nws yog tsim los ntawm yas.

Dab tsi yog 3 pawg ntawm composites?
Nyob rau hauv txhua qhov ntawm cov kab ke no, cov matrix feem ntau yog ib theem txuas ntxiv mus thoob plaws hauv cov khoom.

Polymer Matrix Composite (PMCs) ...

Hlau Matrix Composite (MMCs) ...

Ceramic Matrix Composite (CMCs)

Dab tsi yog qhov txawv ntawm ceramic thiab composite?

Ib qhov sib txawv ntawm cov khoom siv ceramic thiab cov khoom sib xyaw yog cov ceramics muaj kev hnav zoo dua, cov khoom siv kho tshuab thiab muaj kev ntxhov siab tsawg dua ntawm cov hniav nyob ib puag ncig ntawm cov hniav nyiaj hniav kub. Ceramics yog zoo tagnrho rau inlays, cusp kev pab cuam kho kom zoo nkauj xws li crowns thiab onlays, thiab zoo nkauj heev veneers.

Dab tsi yog cov khoom siv sib xyaw ua ke sib zog tshaj plaws?

Ntxiv rau qhov ua cov khoom siv thermally tshaj plaws hauv ntiaj teb, graphene kuj yog cov khoom siv thinnest, lightest thiab muaj zog tshaj plaws puas tau vim nws daim ntawv ob-seem. Raws li CNN, nws muaj txog li 200 npaug zog dua li cov hlau, thiab nyuaj dua li pob zeb diamond.

Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm kev sib xyaw?

Thaum lawv feem ntau raug nqi ntau dua li ntoo, cov ntaub ntawv sib xyaw muab cov lus cog tseg ntawm kev ua haujlwm ntev dua thiab kev saib xyuas tsawg dua.

Puas muaj dab tsi khawb tungsten carbide?

Tungsten carbide muaj qhov nyuaj ntawm 9, raws li qhov ntsuas no, uas txhais tau hais tias nws tuaj yeem khawb cuaj cov zaub mov ntawm kaum thiab tsuas yog pob zeb diamond tuaj yeem khawb tungsten carbide.

Puas yog tungsten carbide xeb hauv dej?

Vim tias tsis muaj hlau nyob hauv tungsten carbide, nws yuav tsis xeb kiag li (saib peb tsab xov xwm ntawm Kev Kho Hinged Instruments kom paub ntau ntxiv txog kev tshem tawm xeb los ntawm pliers). Qhov ntawd tsis txhais hais tias, txawm li cas los xij, carbide yog impervious rau corrosion.

Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa mus rau US MAIL hauv qab ntawm nplooj ntawv no.
