Copper rau EDM: tseem hu ua electrolytic tooj liab
Nyob ib ncig ntawm 1940, lub qub Soviet Academy ntawm Sciences hloov los ntawm anti-electrocorrosion txoj kev siv electrocorrosion phenomena los ua hlau cov ntaub ntawv loj vim hais tias ntawm lub phenomenon ntawm sparks burning nto thaum lub plug qhib thiab kaw. Xyoo 1943, thawj lub tshuab EDM tau tsim, uas tuaj yeem ua 60HRC steel.
2. Txoj kev qhia:
Tuam Tshoj: Resistivity ρ Tsawg dua lossis sib npaug rau 0.0017771 Ω. mm2 / m (20 degree)
EU: Conductivity 1 / ρ Ntau dua lossis sib npaug rau 56.27 MS / m
Teb Chaws Asmeskas thiab Nyiv: Conductivity 56.27 X 1.73=97.34 % IACS
3. Txoj kev deoxidation:
a. Phosphorus
b. Kev tiv thaiv nitrogen
c. Ntxiv alloy
4. Tus nqi: cuam tshuam tus nqi
a. Kev xaiv raw khoom
b. Smelting txheej txheem
