Tungsten Copper Electrode Infiltration Mechanism III

Infiltration is the most widely used in tungsten copper electrode manufacturing so that the study on mechanism of tungsten copper electrode is also important. However, not any two kinds of metal can be used in infiltration.

There are some essential basics for tungsten copper infiltration:

1. Infiltrated metal (Cu) can wet the skeleton material (W) completely.

2. There is a great difference of melting point between skeleton material (W) and infiltrated metal (Cu) in case of the deformation of parts.

3. The solubility of the skeleton (W) and infiltrated metal (Cu) should be low or immiscible so that the liquid phase will disappear when the compounds or solid solution emerging after the reaction.

4. The amount of infiltrated metal (Cu) should be limited by fill-in the pores, more or less will have negative influence.
