Puas yog Ferro Tungsten Sib Nqus?

Txawm hais tias tungsten alloys tuaj yeem pom cov hlau nplaum yog nyob ntawm cov hlau uas lawv fused rau. Cov alloys no yog fused nrog lub ntsiab hlau nrog rau ntau yam kab kawm.

Qhov tseeb, tungsten tuaj yeem siv los tsim ntau cov alloys uas yuav muaj cov khoom sib nqus sib txawv.

Piv txwv li, tungsten hlau yog hlau nplaum vim nws muaj cov hlau uas muaj ferromagnetic hlau. Qhov no kuj tseem muaj cov lej ntawm vanadium thiab molybdenum nrog rau tsawg kawg 8% tungsten.

Tungsten carbide tuaj yeem tso saib cov hlau nplaum, nyob ntawm lwm cov hlau siv hauv cov txheej txheem alloying. Tungsten carbide yuav tsum muaj cov hlau sib txuas kom zoo thiab kev xaiv cov hlau cuam tshuam rau nws cov khoom sib nqus. Yog hais tias cobalt los yog hlau tau muab tso rau hauv cov alloy ces nws yuav sib nqus, ntawm qhov tod tes, yog siv nickel ces nws yuav magnetic.

Muaj ntau yam uas cuam tshuam rau cov khoom sib nqus ntawm tungsten. Cov xwm txheej no suav nrog:

Kub:Qhov xwm txheej no nyob ntawm Curie txoj cai uas hais tias qhov sib nqus ntawm cov khoom siv paramagnetic yog qhov sib npaug ntawm qhov ntsuas kub. Kev nce hauv qhov kub thiab txias txo qhov sib nqus susceptibility, uas ua rau txo qis hauv cov lus teb sib nqus. Qhov kub tsis tshua muaj qhov cuam tshuam qhov sib txawv thiab ua kom cov khoom sib nqus ntawm tungsten.
Siv magnetic teb:Ib qho kev siv magnetic teb cuam tshuam rau kev taw qhia ntawm cov electrons hauv tungsten. Ib qho chaw sib nqus muaj zog tso cai rau lub caij kom tau txais lub peev xwm sib nqus tsis muaj zog ib ntus uas ploj mus thaum lub chaw sib nqus raug tshem tawm.
Cov ntsiab lus Binder:Rau tungsten alloys, binder ntsiab yog siv los yaj cov ntsiab lus sib txawv. Piv txwv li, cobalt paub los txhim kho cov khoom no, thaum nickel inhibits cov nyhuv uas twb muaj lawm, ua rau lub caij tsis sib nqus.
Kev sib xyaw:Qhov tseeb muaj pes tsawg leeg ntawm cov khoom no ncaj qha cuam tshuam rau cov khoom sib nqus ntawm tungsten nrog rau cov xov tooj ntawm cov hluav taws xob tsis sib xws thiab muaj cov dipoles thiab lawv cov kev npaj.

Raws li ib qho tseem ceeb ntawm cov hlau,tungstenmuaj ntau yam kev siv thiab qhov tseem ceeb hauv kev lag luam thiab kev tshawb fawb thiab thev naus laus zis. Cov hauv qab no yog cov kev siv tseem ceeb thiab qhov tseem ceeb ntawm tungsten:


1. High-temperature alloy manufacturing
Tungsten muaj cov ntsiab lus melting siab thiab lub zog siab, ua rau nws yog ib qho tseem ceeb hauv kev tsim cov hlau kub kub. Cov alloys kub kub no feem ntau siv rau hauv aerospace, aeroengines, nuclear zog thiab tshuaj industries, thiab tuaj yeem tiv taus qhov kub thiab txias ib puag ncig.

2. Cov cuab yeej txiav thiab abrasives
Vim lub siab hardness thiab hnav tsis kam ntawm tungsten, tungsten alloys feem ntau siv rau hauv kev tsim cov cuab yeej txiav, xyaum, abrasives thiab cov cuab yeej sib tsoo. Cov cuab yeej no ua lub luag haujlwm tseem ceeb hauv kev ua hlau, mining thiab lwm yam kev lag luam.

3. Kev lag luam Electronics
Tungsten yog siv dav hauv kev lag luam hluav taws xob los tsim cov khoom siv hluav taws xob, lub tshuab nqus tsev, cov khoom siv hluav taws xob thiab cov khoom siv semiconductor. Nws qhov siab melting point thiab stability ua rau nws yog ib qho ntawm cov khoom siv zoo tshaj plaws rau cov khoom siv hluav taws xob.

4. Kev kho mob teb
Tungsten alloys yog siv los tsim cov khoom siv kho mob, cov ntaub ntawv tiv thaiv hluav taws xob thiab cov khoom siv hluav taws xob kho mob. Nws lub siab ntom ntom ntom thiab hluav taws xob tiv thaiv ua rau nws daim ntawv thov tseem ceeb hauv kev kho mob.

5. Nuclear zog teb
Tungsten yog dav siv nyob rau hauv nuclear zog teb los tsim tshuaj tiv thaiv cov ntaub ntawv rau nuclear reactors thiab lwm yam khoom siv hluav taws xob nuclear. Nws lub siab ntom ntom thiab melting taw tes ua nws txoj kev xaiv zoo tshaj plaws rau cov khoom siv hluav taws xob nuclear.

6. Lwm yam kev siv
Tungsten kuj tseem siv los tsim cov alloys high-density, aerospace devices, optical lenses, automotive parts, thiab lwm yam.


Nyob rau hauv luv luv, tungsten, raws li ib tug tseem ceeb engineering cov ntaub ntawv, muaj cov yam ntxwv ntawm lub cev thiab tshuaj, uas ua rau nws ua si lub luag hauj lwm tseem ceeb nyob rau hauv ntau yam teb. Nws cov hardness siab, siab melting point, corrosion kuj thiab seem stability ua rau nws ib tug ntawm indispensable ntaub ntawv nyob rau hauv ntau yam industrial thiab scientific teb. Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov teb ntawm tungsten yuav txuas ntxiv nthuav dav thiab ua kom muaj txiaj ntsig ntau dua rau kev nce qib thiab kev loj hlob ntawm tib neeg lub neej.
