Encapsulated preformed shapes

摘要

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.

主权项

1. 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.
