Infiltrated diamond wear resistant bodies and tools

摘要

Implementations of the present invention include infiltrated diamond tools with increased wear resistance. In particular, one or more implementations of the present invention include a body comprising at least 10% by volume diamond particles that are infiltrated with a binder. Implementations of the present invention also include drilling systems including such infiltrated diamond tool, and methods of forming and using such infiltrated diamond tools.

主权项

1. A solidified infiltrated tool configured to be resistant to wear, wherein the solidified infiltrated tool is selected from the group consisting of a drill bit body, a wear pad, and a wear strip, the solidified infiltrated tool comprising:
a matrix having a hard particulate material and a plurality of diamond particles dispersed throughout the hard particulate material; and a binder comprising a copper-based infiltrant, wherein the diamond particles comprise between about 35 percent and about 75 percent by volume of the solidified infiltrated tool, and wherein the binder secures the hard particulate material and the diamond particles together, wherein the diamond particles comprise the largest component by volume of the solidified infiltrated tool, wherein the diamond particles are substantially homogenously dispersed throughout the solidified infiltrated tool, and wherein the diamond particles are configured to provide the primary defense against wear and erosion of the solidified infiltrated tool.
