Abstract
Wellbore drill bits can be used for excavation through subterranean formations for extracting hydrocarbons from a reservoir. Wellbore drill bits can experience excessive force during extraction processes. Drill bits can be assembled with resilience. Thus, treating a subsurface of a metallic blank material by adding one or more elements to the subsurface of the metallic blank material inhibits chemical interactions between a metal binding mixture and one or more construing alloying agents of the metallic blank material. The metallic blank material and a reinforcing agent can be positioned in the drill bit mold to begin an infiltration process where the metal binding mixture fills gaps between the metallic blank material and the reinforcing agent to generate a metal-matrix composite.

A method comprising:
- treating a subsurface of a metallic blank material by adding one or more elements to the subsurface of the metallic blank material to inhibit interaction between a metal binding mixture and one or more construing alloying agents of the metallic blank material;
- and
- positioning the metallic blank material and the metal binding mixture in a drill bit mold to form a metal-matrix composite to form a wellbore drill bit via an infiltration process.
A method comprising:
- treating a surface of a metallic blank material by coating the surface of the metallic blank material with one or more chemical compounds to inhibit interaction of a metal binding mixture with construing alloying agents of the metallic blank material;
- and
- positioning the metallic blank material and the metal binding mixture in a drill bit mold to form a metal-matrix composite to form a wellbore drill bit via an infiltration process.
A method comprising:
- treating a metal binding mixture with one or more chemical components to inhibit interaction of a metal binding mixture with construing alloying agents of a metallic blank material;
- and
- positioning the metallic blank material and the metal binding mixture in a drill bit mold to form a metal-matrix composite to form a wellbore drill bit during an infiltration process.
