Qhov sib txawv ntawm tungsten thiab tungsten carbide

Hauv kev lag luam niaj hnub no, tungsten carbide cov khoom tau dhau los ua cov khoom siv nrov. Thiab tungsten tsis yog siv rau lub teeb xwb. Hauv tsab xov xwm no, peb yuav tham txog qhov sib txawv ntawm tungsten thiab tungsten carbide. Kab lus no yuav piav qhia raws li hauv qab no:

1. Dab tsi yog tungsten?

2. Dab tsi yog tungsten carbide?

3. Qhov sib txawv ntawm tungsten thiab tungsten carbide.

tungsten yog dab tsi?

Tungsten tau pom thawj zaug hauv xyoo 1779, thiab nws tau hu ua "lub pob zeb hnyav" hauv Swedish. Tungsten muaj cov ntsiab lus melting siab tshaj plaws, qhov qis tshaj qhov nthuav dav coefficient, thiab qis tshaj vapor siab ntawm cov hlau. Tungsten kuj muaj zoo elasticity thiab conductivity.

Dab tsi yog tungsten carbide?

Tungsten carbide yog ib qho alloy ntawm tungsten thiab carbon. Tungsten carbide yog lub npe hu ua cov khoom siv nyuaj tshaj plaws hauv ntiaj teb, tom qab pob zeb diamond. Dhau li ntawm hardness, tungsten carbide kuj muaj kev hnav zoo, corrosion kuj, poob siab, thiab kav ntev.

Qhov sib txawv ntawm tungsten thiab tungsten carbide

Peb tab tom tham txog qhov sib txawv ntawm tungsten thiab tungsten carbide hauv cov hauv qab no:

1. Elastic modulus

Tungsten muaj qhov loj elastic modulus ntawm 400GPa. Txawm li cas los xij, tungsten carbide muaj qhov loj dua ntawm ib ncig ntawm 690GPa. Feem ntau, cov ntaub ntawv nruj yog cuam tshuam nrog elastic modulus. Qhov siab dua modulus ntawm elasticity ntawm tungsten carbide qhia tau hais tias muaj zog dua thiab siab dua rau deformation.

2. Shear modulus

Shear modulus yog qhov piv ntawm shear stress rau shear strain, uas tseem hu ua modulus ntawm rigidity. Feem ntau hais lus, cov hlau feem ntau muaj qhov sib txawv ntawm 80GPa, tungsten muaj ob zaug, thiab tungsten carbide peb zaug.

3. Tensile yield zog

Txawm hais tias tungsten thiab tungsten carbide muaj hardness thiab toughness, lawv tsis muaj zog tensile siab zog. Feem ntau, tensile yield zog ntawm tungsten yog nyob ib ncig ntawm 350MPa, thiab tungsten carbide yog nyob ib ncig ntawm 140MPa.

4. Thermal conductivity

Thermal conductivity yog ib qho tseem ceeb ntsuas thaum cov khoom siv nyob rau hauv ib tug high-kub ib puag ncig. Tungsten muaj thermal conductivity ntau dua li tungsten carbide. Tungsten muaj qhov kub thiab txias, yog li nws tsim nyog rau qee qhov kev siv thermal, xws li filaments, raj, thiab cua sov coils.

5. Hardness

Tungsten muaj ib tug hardness ntawm 66, thaum tungsten carbide muaj ib tug hardness ntawm 90. tungsten carbide muaj tungsten thiab carbon, yog li nws tsis tsuas yog muaj cov khoom zoo ntawm tungsten, tab sis nws kuj muaj hardness thiab tshuaj stability ntawm carbon.

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 US MAIL hauv qab ntawm nplooj ntawv.
