tungsten tooj liab yog ib qho alloy ntawm tungsten thiab tooj liab, siv cov thev naus laus zis ntawm isostatic nias, kub kub sintering ntawm tungsten moj khaum, thiab cov tshuaj infiltration ntawm tooj liab.

(1) Kev tiv thaiv vuam electrodes qhia txog qhov zoo ntawm tungsten thiab tooj liab, suav nrog kev kub siab ua haujlwm, arc yaig tsis kam, siab zog, siab lub ntiajteb txawj nqus, zoo conductivity thiab thermal conductivity, yooj yim txiav thiab ntau lawm, thiab hws txias zog. Vim lub siab hardness, siab melting point, thiab anti adhesion yam ntxwv ntawm tungsten, lawv feem ntau yog siv los ua projection vuam thiab taub qab vuam electrodes nrog tej yam hnav tsis kam thiab kub tsis kam.

(2) Thaum cov hluav taws xob hluav taws xob siv rau cov pwm ua los ntawm tungsten steel thiab kub-resistant superhard alloys uas yuav tsum tau hluav taws xob yaig, zoo tib yam electrodes muaj siab poob thiab qeeb ceev. Tus nqi siab corrosion, tsis tshua muaj tus nqi, qhov zoo electrode zoo, thiab kev ua haujlwm zoo heev ntawm tungsten tooj liab tuaj yeem txhim kho qhov tseeb ntawm cov khoom tsim.

(3) Thaum lub sijhawm ua haujlwm ntawm high-voltage lub tshuab nqus tsev vacuum, qhov kub ntawm cov khoom tiv tauj yuav nce li ob peb txhiab degrees Celsius hauv ob peb feeb xwb. Thiab tungsten tooj liab lub siab tiv thaiv ablation muaj nuj nqi, siab tsis kam, zoo heev conductivity thiab thermal conductivity muab cov xwm txheej tsim nyog rau kev ua haujlwm ruaj khov ntawm cov raj xa tawm.

(4) Cov khoom ntim khoom siv hluav taws xob muaj ob qho tib si tsis tshua muaj kev nthuav dav ntawm tungsten thiab cov thermal conductivity siab ntawm tooj liab. Lawv cov thermal expansion coefficient thiab conductivity tuaj yeem hloov kho los ntawm kev kho cov khoom muaj pes tsawg leeg, uas muab kev yooj yim rau kev siv cov khoom.
