Co-doped Effects on Tungsten Copper Electrode III

Sintering additives, which can dissolve tungsten, can be used for decreasing the porosity of tungsten copper electrode. The most common method is to add active elements, which takes advantage of active elements to dissolve tungsten and improve phase precipitation, round and accumulation, to obtain a high density. It can remarkably improve the properties of tungsten copper, decrease the sintering temperature and shorten the sintering time. The effect of different content of Co element on the hardness of tungsten copper electrode as follow:

We can learn from the graph that the effect of Co element on the hardness of tungsten copper electrode is similar to the density of tungsten copper electrode, which remarkably increases at the beginning and tends to stabilization or decrease. When the content of cobalt is about 0.3%, the density and hardness of tungsten copper electrode reaches the maximum 16.69g/cm³, and HB311.6.
