Title: Innovations by Nathan R Anderson
Introduction
Nathan R Anderson is a notable inventor based in Pleasant Grove, UT (US). He has made significant contributions to the field of materials science, particularly in the development of polycrystalline diamond materials. With a total of 10 patents to his name, Anderson's work has advanced the capabilities of materials used in various industrial applications.
Latest Patents
One of Anderson's latest patents focuses on polycrystalline diamond materials formed from coarse-sized diamond grains. This invention involves creating PCD materials that comprise diamond crystals bonded together with a catalyst/binder material. The preparation process includes combining diamond grains with the catalyst/binder material, either as a premixture or through infiltration during sintering. The resulting PCD material contains 15 percent by volume or less of diamond grains sized 20 micrometers or less. These diamond grains are subjected to elevated temperature conditions to achieve the desired PCD material properties. The PCD materials exhibit improved impact and fatigue resistance, as well as functional toughness, especially in complex wear environments, compared to conventional PCD materials that utilize fine-sized diamond grains.
Another significant patent by Anderson is for a toughness-optimized insert for rock and hammer bits. This insert features an exposed surface with a contact portion designed to periodically engage with earthen formations. The contact portion is made from polycrystalline diamond material, which has a hardness ranging from about 2000 HV to about 3000 HV. In certain embodiments, the polycrystalline diamond material includes a composite that combines polycrystalline diamond with oxide particulates, metal carbides, and metallic particulates, among others.
