Daim ntawv thov tseem ceeb ntawm tungsten- tooj liab Alloys

tungsten- tooj liab alloys muab qhov zoo ntawm ob qho tib si tungsten thiab tooj liab. Tungsten muaj lub siab melting point (3410 degree, tooj liab 1080 degree) thiab siab ceev (19.34 g / cm³, tooj liab 8.89 g / cm³); tooj liab muaj zoo heev hluav taws xob thiab thermal conductivity. tungsten- tooj liab alloys (feem ntau xws li WCu7 txog WCu50) muaj cov qauv microstructure, kub tsis kam, siab zog, tsis kam mus rau arc yaig, thiab siab ceev. Lawv kuj muaj cov hluav taws xob nruab nrab thiab thermal conductivity, ua rau lawv siv dav hauv cov tub rog siab - cov ntaub ntawv kub, hluav taws xob alloys rau siab -voltage switches, EDM electrodes, thiab microelectronic cov ntaub ntawv. Raws li cov khoom siv thiab cov khoom siv, lawv tau siv dav hauv aerospace, aviation, electronics, fais fab, metallurgy, machinery, thiab cov khoom ua si.

Tub Rog Siab -Cov Khoom Kub Kub: Tungsten- tooj liab alloys yog siv nyob rau hauv aerospace rau missile thiab foob pob ua ntxaij cav nozzles, roj turbine tswj chaw, huab cua rudders, thiab lub qhov ntswg cones. Cov kev cai tseem ceeb yog qhov kub thiab txias tsis kam (3000K ~ 5000K) thiab tsis kam mus rau siab -kub airflow yaig. Qhov no yog ua tiav feem ntau los ntawm kev siv cov nyhuv txias ntawm tooj liab volatilization ntawm qhov kub thiab txias (tooj liab melting point 1083 degree) kom txo qhov kub ntawm qhov chaw ntawm tungsten- tooj liab alloy, kom ntseeg tau tias nws siv nyob rau hauv huab cua kub heev - kub.

High-Voltage Switchgear Alloys: Tungsten- tooj liab alloys yog dav siv nyob rau hauv 128kV SF6 Circuit Court breakers (WCu/CuCr), siab -voltage nqus load switches (12kV 40.5KV 1000A), thiab surgers ntes. High-voltage lub tshuab nqus tsev hloov pauv me me, yooj yim los tswj, thiab muaj ntau yam kev siv, muaj peev xwm ua haujlwm hauv qhov chaw ntub dej, nplaim taws, tawg, thiab corrosive ib puag ncig.

Hluav taws xob tawm Machining Electrodes: Thaum ntxov hluav taws xob tawm machining electrodes siv tooj liab lossis graphite electrodes, uas pheej yig tab sis tsis tiv taus ablation. Cov no tau raug hloov loj los ntawm tungsten- tooj liab electrodes. Qhov zoo ntawm tungsten- tooj liab electrodes muaj xws li kub tsis kam, siab siab - kub lub zog, tsis kam mus rau arc yaig, thiab zoo hluav taws xob thiab thermal conductivity nrog sai sai tshav kub dissipation. Cov ntawv thov yog tsom rau hauv cov hluav taws xob tawm hluav taws xob, tiv thaiv vuam electrodes, thiab siab -voltage discharge tube electrodes.

Hauv cov khoom siv hluav taws xob microelectronics, tungsten{0}} tooj liab cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ua kom sov muaj ob qho kev nthuav dav ntawm tungsten thiab siab thermal conductivity ntawm tooj liab. Lawv coefficient ntawm thermal expansion thiab thermal thiab hluav taws xob conductivity tuaj yeem hloov kho los ntawm kev kho qhov sib xyaw ntawm tungsten- tooj liab alloy, yog li muab ntau yam kev siv.
