Tuam Tshoj W90Cu10 tungsten tooj liab bar rau EDM Chaw tsim tshuaj paus thiab tsum

W90Cu10 tungsten tooj liab bar rau EDM

Lus piav qhia luv luv:

Qhov muaj pes tsawg leeg ntawm W90Cu10 qhia tias tus pas nrig yog tsim los ntawm 90% tungsten thiab 10% tooj liab. Qhov kev sib xyaw ua ke no muab cov khoom tsim nyog rau EDM daim ntawv thov, xws li siab hardness thiab thermal conductivity. Cov ntsiab lus tungsten pab ua kom cov khoom hardness thiab hnav tsis kam, thaum tooj liab txhim kho nws cov hluav taws xob thiab thermal conductivity.

Koj puas tuaj yeem EDM tooj liab tungsten?

Yog lawm, tooj liab tungsten tuaj yeem siv los ua cov khoom siv hluav taws xob hauv hluav taws xob tawm tshuab (EDM). Tooj-tungsten yog cov khoom sib xyaw ua ke ntawm tooj liab thiab tungsten, uas muaj cov hluav taws xob zoo thiab thermal conductivity, siab melting point thiab zoo hnav tsis kam. Cov khoom no ua rau nws haum rau EDM daim ntawv thov.

Thaum siv tooj liab-tungsten electrodes rau EDM, nws yog ib qho tseem ceeb uas yuav tau xav txog tej yam xws li cov ntsiab lus tshwj xeeb ntawm cov khoom siv tooj liab-tungsten, hom khoom siv ua haujlwm, thiab EDM tsis xws li tso tawm tam sim no, mem tes ntev, thiab dej ntws tawm. Kev xaiv kom raug thiab teeb tsa ntawm EDM cov cav tov kuj tseem ceeb heev rau kev ua tiav cov txiaj ntsig machining xav tau.

Zuag qhia tag nrho, tooj liab tungsten yog ib qho siv tau thiab feem ntau siv EDM cov khoom siv hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas yuav tsum tau hnav tsis kam thiab thermal conductivity.

Lub hardness ntawm tungsten tooj liab yog dab tsi?

Lub hardness ntawm tungsten-tooj liab composites yuav txawv nyob ntawm seb muaj pes tsawg leeg thiab cov txheej txheem ua. Feem ntau hais lus, tungsten tooj liab alloys muaj siab hardness, ua rau lawv haum rau daim ntaub ntawv uas hnav tsis kam thiab lub zog tseem ceeb.

Lub hardness ntawm tungsten tooj liab feem ntau yog ntsuas siv Rockwell lossis Vickers hardness nplai. Tungsten-tooj liab composites muaj hardness qhov tseem ceeb xws li 70 HRC (Rockwell C) mus rau ntau tshaj 90 HRC, qhia tau hais tias muaj zog tiv thaiv deformation thiab hnav.

Lub hardness ntawm tungsten tooj liab ua rau nws zoo tagnrho rau ntau yam kev thov, xws li hluav taws xob tiv tauj, vuam electrodes thiab EDM electrodes, qhov twg cov khoom yuav raug rau siab mechanical thiab thermal stresses.

Puas yog tungsten muaj siab hardness?

Yog lawm, tungsten paub txog nws qhov nyuaj heev. Qhov tseeb, tungsten muaj lub zog tensile siab tshaj plaws ntawm cov hlau ntshiab thiab paub txog nws qhov tshwj xeeb hardness thiab hnav tsis kam. Qhov no ua rau nws muaj txiaj ntsig zoo nrog ntau yam kev siv, suav nrog cov cuab yeej txiav, kev siv kub thiab cov khoom siv uas yuav tsum tau hnav tsis kam.
