Tooj tungsten feem ntau yog ua los ntawm cov txheej txheem hu ua infiltration. Nyob rau hauv cov txheej txheem no, tungsten hmoov yog tov nrog ib tug binder khoom los tsim ib lub cev ntsuab. Lub compact yog ces sintered los ua ib tug ntxeem tau tungsten skeleton. Cov pob txha tungsten ntxeem tau yog ces infiltrated nrog molten tooj liab nyob rau hauv qhov kub thiab txias. Tooj liab sau cov pores ntawm tungsten skeleton los tsim cov khoom sib xyaw uas muaj cov khoom ntawm tungsten thiab tooj liab.

Cov txheej txheem infiltration tuaj yeem tsim tooj liab tungsten nrog cov khoom sib txawv thiab cov khoom, ua rau nws tsim nyog rau ntau yam kev siv xws li hluav taws xob tiv tauj, electrodes thiab cov dab dej kub.

Copper-tungsten yog siv rau ntau yam kev siv vim nws cov khoom sib xyaw ua ke. Qee qhov kev siv feem ntau suav nrog:

1. Kev sib cuag hluav taws xob: tooj liab tungsten feem ntau yog siv rau hauv kev sib cuag hluav taws xob rau kev siv hluav taws xob siab thiab kev siv tam sim no vim nws cov hluav taws xob zoo heev thiab thermal conductivity, nrog rau arc tsis kam thiab hnav tsis kam.

2. Electrode: Vim nws qhov siab melting point, zoo thermal conductivity, thiab corrosion kuj, nws yog siv nyob rau hauv kuj welding electrodes, EDM (hluav taws xob paug machining) electrodes, thiab lwm yam khoom siv hluav taws xob thiab thermal.

3. Aerospace thiab Defense: Tungsten tooj liab yog siv nyob rau hauv aerospace thiab tiv thaiv kev lag luam rau foob pob ua ntxaij nozzles, hluav taws xob tiv tauj hauv aircraft, thiab lwm yam uas yuav tsum tau muaj zog, hnav tsis kam, thiab thermal conductivity.

4. Thaum tshav kub kub dab dej: Siv los ua lub dab dej kub rau cov khoom siv hluav taws xob vim nws cov thermal conductivity thiab qhov seem stability.

Tungsten yog heev resistant rau xeb thiab corrosion. Vim nws inertness, tungsten yuav tsis oxidize los yog xeb nyob rau hauv ib txwm tej yam kev mob. Cov cuab yeej no ua rau tungsten yog ib qho khoom siv tseem ceeb hauv kev siv qhov kev tiv thaiv corrosion tseem ceeb.

Tungsten tooj liab paub txog nws cov hardness siab. Lub hardness ntawm tungsten tooj liab tuaj yeem sib txawv nyob ntawm seb muaj pes tsawg leeg thiab kev ua haujlwm, tab sis feem ntau, nws nyuaj dua li tooj liab ntshiab vim muaj cov tungsten. Cov cuab yeej no ua rau tungsten tooj liab haum rau cov ntawv thov uas hnav tsis kam thiab ua haujlwm ntev yog qhov tseem ceeb. Lub hardness ntawm tungsten tooj liab ua rau nws zoo tagnrho rau siv nyob rau hauv hluav taws xob tiv tauj, electrodes, thiab lwm yam khoom uas yuav tsum tau resistant rau hnav.
