Latest Patents

James U Nixon holds a patent for "PCD cutters with improved strength and thermal stability." This invention describes a thermally stable polycrystalline diamond cutter and a method for fabricating the same. The cutter features a substrate and a cutting table that is bonded to it. The cutting table includes a cutting surface, a first beveled edge, a second beveled edge, a side surface, and an opposing surface adjacent to the substrate. The first beveled edge extends outwardly at a first angle from the cutting surface towards the substrate, while the second beveled edge extends outwardly at a second angle from the first beveled edge towards the substrate. The side surface connects the second beveled edge to the opposing surface. The cutting table is constructed from a polycrystalline diamond structure that has interstitial spaces and a catalyst material within those spaces in an untreated layer, which does not extend into a treated layer. The untreated layer encompasses the entire side surface.
