Electrical Discharge Machining (EDM) is a manufacturing process that shapes a workpiece by using sparks generated through electrical discharges. A dielectric fluid separates two electrodes across which a voltage is applied, creating a rapidly fluctuating periodic electrical discharge to machine the
Carbon felt, also known as carbon fiber felt, turns into graphite felt when heated to nearly 3,000 degrees under an oxygen-free environment. After being made into graphite fiber felt, its usable temperature can reach over 2,800 degrees. That is to say, graphite felt is more resistant to high tempera
Amorphous graphite—also known as earthy graphite, microcrystalline graphite, or black lead powder—does not actually lack graphite crystals as its name might suggest; rather, its crystals are extremely small, forming a microcrystalline structure. X-ray analysis reveals that amorphous earthy graphite
