Melt Infiltration Method Prepares Tungsten Copper Rod

Tungsten has a melting point 3410 °, the boiling point of copper 2 567 ℃. Because copper is much higher than the melting point of tungsten and tungsten and copper boiling immiscible, thus tungsten copper alloy rod casting method can not be used to the system. Melt infiltration method prepares tungsten copper rod can improve the compactness of tungsten copper rod and other material properties.

Principle of melt infiltration method prepares tungsten copper rod is that the use of a capillary force, the low melting point metal wetting liquid filling certain density and strength of the porous matrix skeleton. The molten metal flow to fill the gap along the porous particles of tungsten skeleton pore, resulting in denser materials, greatly improve the toughness of tungsten copper rods.

There are some drawbacks of melt infiltration method prepares tungsten copper rod: Because liquefied copper tungsten skeleton pore capillary action alone infiltration densification therefore slower, less densification. Copper solidified coarse and distribution is not uniform, but will make high temperature sintering tungsten particles grew up together, forming a thick uneven tissue.
