Khoom Description
Copper tungsten (CuW, WCu) tau raug lees paub tias yog cov khoom siv hluav taws xob zoo heev thiab cov khoom siv hluav taws xob tiv thaiv cov khoom siv uas feem ntau siv los ua tooj liab tungsten electrodes hauv EDM machining thiab tsis kam vuam daim ntawv thov, hluav taws xob tiv tauj hauv kev siv hluav taws xob siab, thiab cov khoom siv hluav taws xob thiab lwm yam khoom siv hluav taws xob. hauv kev siv thermal.
Qhov feem ntau tungsten / tooj liab piv yog WCu 70/30, WCu 75/25, thiab WCu 80/20. Lwm cov khoom muaj xws li tungsten / tooj liab 50/50, 60/40, thiab 90/10. Qhov ntau ntawm cov khoom sib xyaw yog los ntawm Cu 50 wt.% mus rau Cu 90 wt.%. Peb cov khoom siv tungsten tooj liab muaj xws li tooj liab tungsten pas nrig, ntawv ci, ntawv, phaj, raj, tungsten tooj liab pas nrig, thiab machined qhov chaw.

Daim ntawv thov
Kev siv tungsten tooj liab (W-Cu) tau pom tau nce ntau hauv ntau qhov chaw thiab kev siv vim nws cov khoom sib txawv thiab cov khoom siv thermophysical. Nws tau siv dav rau kev tsim hluav taws xob tiv tauj, lub tshuab hluav taws xob thiab cov khoom sib kis, tuag-sinking EDM electrodes thiab roj txhaj tshuaj nozzles.
