Abstract
Hardfacing is used to protect wear surfaces of drill bits and other downhole tools. A hardfacing member can be formed by heating a metal matrix material, e.g., via a laser process, injecting a plurality of particles into the heated metal matrix material, disposing the mixture on at least a portion of a substrate thereby forming a hardfacing member having a particle-embedded metal matrix material, and attaching the hardfacing member to a main body.
Claims17
A method comprising:
- injecting a plurality of particles into a heated metal matrix material thereby forming a mixture of the particles and the heated metal matrix material, wherein the plurality of particles are in a bimodal distribution of particles having large size particles in the range between about 200 μm and about 1 mm constituting between 30-70 weight percentage of the plurality of particles and small size particles in the range between about 15 μm and 125 μm constituting the remaining weight of the plurality of particles;
- disposing the mixture on at least a portion of a substrate thereby forming a hardfacing member having the substrate and a particle-embedded metal matrix material;
- and
- removably attaching the hardfacing member to a main body of a rotary steerable pad of a rotary steerable tool via a removable attachment mechanism.
