Abstract
Composite wear parts including encapsulated preformed ceramic shapes are disclosed. Preformed ceramic shapes are embedded in a metal alloy to protect the base metal from abrasion. The preformed ceramic shapes may have a uniform, preformed geometry that provides for packing the preformed ceramic shapes together in a uniform way. The preformed ceramic shapes may be positioned at a location in the composite wear part exposed to an abrasion without using a binding agent. The preformed ceramic shapes may also be contained in a porous container. A truss structure may be integrated in the preformed ceramic shapes to compartmentalize the preformed ceramic shapes into multiple isolated sub regions to stiffen the composite wear parts.
Claims21
A composite wear part to provide abrasion resistance for a tool, the composite wear part comprising:
- a mechanism to removeably couple the composite wear part to a tool to provide for replacing the composite wear part;
- a base metal;
- a plurality of preformed ceramic shapes embedded in the base metal, the base metal substantially permeating the plurality of preformed ceramic shapes, and the preformed ceramic shapes comprising:
- a plurality of elements having a uniform, preformed geometry, the preformed geometry being such that the plurality of preformed ceramic shapes are configured to pack together in a uniform way to provide for being positioned at a location in the composite wear part exposed to an abrasion without using a binding agent to retain the plurality of preformed ceramic shapes at the location.
A composite wear part removeably coupled to a piece of equipment, the composite wear part comprising:
- a body having a wear surface, the body comprising:
- a base metal;
- and
- a plurality of preformed ceramic shapes embedded in the base metal, the preformed ceramic shapes comprising:
- a plurality of elements having a uniform, preformed geometry, the preformed geometry being such that the plurality of preformed ceramic shapes are configured to pack together in a uniform way to provide for being positioned over at least a portion of the wear surface to improve resistance of the wear surface to abrasion.
An abrasion-resistant composite component comprising:
- a body having a wear surface exposed to an abrasion, the body comprising:
- a plurality of preformed ceramic shapes arranged in one or more layers of uniform arrays and embedded in a base metal, and the preformed ceramic shapes comprising,
- a plurality of elements having a uniform, preformed geometry, the preformed geometry being such that the plurality of preformed ceramic shapes are configured to be:
- packed together in a uniform way;
- and
- positioned over at least a portion of the wear surface exposed to the abrasion to improve resistance of the wear surface to the abrasion.
