Product Introduction:

Different types of tungsten carbide have big differences in hardness, toughness, cladding properties, etc.

During use, one or several mixtures can be reasonably selected as the hard ceramic phase according to the working conditions.

A special process is used to mix tungsten powder and carbon black, and carbonize in a high-temperature carbonization furnace to obtain single crystal tungsten carbide.

The hardness and toughness of this tungsten carbide are between cast tungsten carbide and sintered tungsten carbide.

At the same time, it has good wettability to iron group metals.

However, the content of single crystal tungsten carbide in the surface layer composite material cannot be too high,

otherwise, the single crystal tungsten carbide is very prone to bridging, especially during the laser cladding process.

The bonding force between the bridging surfaces is very weak, and it is easy to damage from there under external load,

which causes the tungsten carbide to peel off and reduce the wear resistance.

Applications:

It is mainly used hard phases in PDC matrix powder, PTA surfacing and HVOF flame spray materials,

cemented carbide rod(wire),as well as raw materials in cemented carbide production,construction,

agricultural machinery steel industry.
