Tungsten–copper composite production by activated sintering and infiltration

Activated sintering of tungsten has been used to have infiltrable skeletons. For this purpose the effects of sintering temperature and activator amount were studied and appropriate production parameters were obtained. The results showed that by activated sintering, moderate sintering temperature such as 1400 °C can be used instead of conventional temperatures i.e. > 2000 °C. Activated sintering has the ability to produce fully open and interconnected porosities with desirable density that is ideal for infiltration. This method of production for infiltrated W–Cu composites has not been reported elsewhere. ► Precious study of tungsten activated sintering and description of all observed trends especially bimodal porosity development. ► Use of activated sintering and infiltration for tungsten-copper composites production that has not investigated well. ► Study of Infiltration efficiency vs. different production parameters.
