Latest Patents

One of Heeman Choe's latest patents is a method of making an earth-boring particle-matrix rotary drill bit. This method involves creating a bit body designed to carry one or more cutters for engaging subterranean earth formations. The process includes providing a plurality of hard particles in a mold to define a particle precursor of the bit body. The particle precursor is then infiltrated with a molten matrix material that comprises a shape memory alloy, forming a hard particle-molten matrix material mixture. The molten matrix material is cooled to solidify and form a bit body that consists of a particle-matrix composite material with hard particles randomly dispersed throughout.

Another notable patent involves methods of forming earth-boring rotary drill bits that include bit bodies with boron carbide particles in aluminum or aluminum-based alloy matrix materials. This method entails forming a plurality of boron carbide particles into a body that corresponds to a portion of a rotary drill bit's bit body. The boron carbide particles are infiltrated with molten aluminum or aluminum-based material, which is then cooled to create a solid matrix material surrounding the boron carbide particles.
