Why Tungsten Carbide Grit Is Good for Hardfacing Applications?
Tungsten Carbide Grit is well-known for use in hardfacing applications such as on rotary rock bits and tool joint connections that are used primarily in well drilling where tools must withstand severe abrasion and the stresses of high impacts.
How Tungsten Carbide Grits Are Made?
Manufacturers in the prior art, grits have been made by crushing and screening tungsten carbide compositions. This method produced sharp faceted, irregularly shaped particles with inferior wear resistance. It was recognized in U.S. that the irregularly shaped grit obtained by crushing tungsten carbide compositions were subject to wear problems because of the points and pressures on the rits and the lack of uniformity in the grit particles. This patent teaches a method for preparing tungsten carbide powders whereby spheres, cylinders, ovoids or cubes of tungsten carbide can be obtained for use of a tumbling procedure is mentioned for the production of tungsten carbide grit but no mention is made as to how this procedure is to be carried out.
It has been discovered on the later half that if tungsten carbide powder is combined with a suitable organic binder and agglomerated into particles which are sintered to remove the binder and form tungsten carbide grit, grit with blunt and round particles. These blunt tungsten carbide grits are obtained in good yield with a minimum of unusable fine material. The blunt tungsten carbide grit has superior wear resistance properties as compared to the tungsten carbide grit obtained by crusing tungsten carbide blocks or compacts.
Tungsten Carbide Grit and Hardfacing
The process involved in applying tungsten carbide grit to the surface of hardfacing parts. With hardfacing, the base metal is made tougher and harder through the application of a material (in this case tungsten carbide grit) to its surface. Tungsten carbide grit in fact offers a greater level of protection to surfaces than many or most other traditional hardfacing materials.
Various industry applications require various levels of wear resistance. At WEISON, we offer tungsten carbide grit in various mesh sizes that suit particular applications. By using the right mesh size, you can achieve the desired level of protection regarding both impact and abrasion resistance. Tungsten carbide grit can also be applied to use parts in order to restore their deteriorated and worn-down surfaces.
