CEMENTED CARBIDE COMPOSITE FOR A DOWNHOLE TOOL

摘要

A carbide composite for a downhole tool may be formed by depositing a first layer on a substrate, and a second layer at least partially adjacent to the first layer. The first and second layers may each include carbides, metal binders, organic binders, or a combination thereof. The first and second carbide layers may have a different particle size, particle shape, carbide concentration, metal binder concentration, or organic binder concentration from one another.

1. A carbide composite for a downhole tool, comprising:
a carbide layer, the carbide layer comprising tungsten carbide and cobalt; and a second layer at least partially adjacent to and bound to the carbide layer, the second layer comprising one or more carbides, metal binders, organic binders, or a combination thereof, the carbide layer and second layer having a different particle size, particle shape, carbide concentration, metal binder concentration, or organic binder concentration from one another.
