The electrode surface erosion degree by pulse arc is related with pulse arc electricity and energy. For tungsten copper materials,  the main form of electrode erosion is the evaporating of electrode material. The effect on tungsten copper material of pulse is positively correlated with the single pulse charge transfer and total pulse charge transfer.

It is very difficult for a single metal material possess such advantages of  high melting point,high density, high specific heat capacity and high thermal conductivity. Experiments show that using tungsten copper alloy switch,which has high density, high melting point and high conductivity as switching electrode material will have good corrosion resistance.

However, under the pulse arc action, the surface  of tungsten copper electrode will form scaly cracking, which is due to the structural weaknesses of tungsten powder cracking and tungsten copper materials pore.It will form and expand the crack.
