Can micro-electrode wear reduced by powder coating before using it in micro-EDM machining?
Using Thermal Evaporation Coating If I coat the the Copper-Tungsten electrode with fine powder, Can the performance of electrode be improved?
Which material powder can be used for coating?
Dear Elias Sir,
If i use Aluminium alloy then how will it help to reduce electrode wear rate of Micro-Electrodes of diameter 300 micrometer.
Can I use Thermal Evaporation Coating method to coat the Cu-W electrode using Aluminium alloy.
Quick and easy answers on what basis.
First and foremost, we must distinguish whether Sinking EDM (SEDM), or want to operate WEDM. The conclusions from the WEDM are not entirely applicable to the SEDM. The coated wires cause local for a short time and its coating is useful because the wire breakage is prevented. In the SEDM highly conducting electrodes are usually more efficient. Then coatings can be advantageous when working with higher pulse energies for micromachining. Still, I would rather are trying to work with small pulse energies and higher pulse sequences.
Dear Schulze,
I agree with you.
I am working on producing micro-holes using micro-Tungsten electrode of Dia. 300 micrometer in micro-EDM drilling process.
I want to reduce the wear of electrode using some kind of electrode coating. So please tell me. Which type of coating could reduce electrode wear in micro-EDM drilling. Then also. tell me which coating material is suitable to coat wither Tungsten or Copper-Tungsten electrodes.?
