Abstract
In accordance with the present invention, a method for manufacturing tungsten carbide components is provided. The method includes forming a composite material out of tungsten carbide powder and binder powder, pressing the composite material into a plurality of components, heating the plurality of components, optionally under pressure, to liquefy the binder, cooling the plurality of components until the binder solidifies, optionally grinding each of the plurality of components to a desired size, and cascading the plurality of components in a cascading machine under high energy conditions.
Claims40
A method for manufacturing cemented tungsten carbide components, comprising:
- forming a composite material out of tungsten carbide powder and binder powder;
- pressing the composite material into a plurality of components;
- heating the plurality of components under pressure to liquefy the binder;
- cooling the plurality of components until the binder solidifies;
- cascading the plurality of components in a cascading machine in a low-energy processing media including an abrasive under low-energy conditions;
- and
- cascading the plurality of components in the cascading machine in a high-energy processing media different from the low-energy media which does not include an abrasive under high-energy conditions.
A method of increasing the surface hardness of cemented tungsten carbide components, comprising:
- cascading the plurality of components in a cascading machine in a low-energy processing media including an abrasive under low energy conditions;
- and
- cascading a plurality of tungsten carbide components in the cascading machine in a high-energy processing media different from the low-energy media which does not include an abrasive under high-energy conditions.
A method, comprising:
- cascading a plurality of tungsten carbide components in a cascading machine in a low-energy processing media consisting essentially of a cutting abrasive and water under low-energy conditions;
- and
- cascading the plurality of tungsten carbide components in the cascading machine in a high-energy processing media different from the low-energy media and consisting essentially of a detergent and water under high-energy conditions.
