Drilling tools made of wurtzite boron nitride (W-BN)
Systems and methods include a computer-implemented method that can be used to manufacture drilling tools from new wurtzite boron nitride (w-BN) superhard materials. The pure w-BN powder is subjected to an ultrahigh pressure high temperature operation to synthesize w-BN and cubic boron nitride (c-BN) briquettes having a first size greater than particles of the pure w-BN powder. The ultrahigh pressure high temperature operation includes pressurizing the w-BN powder to a pressure of about 20 GPa, heating the w-BN powder at a heating rate of 100 DEG C/min, and cooling the w-BN powder at a cooling rate of 50 DEG C/min. The compact is cut to a second size smaller than the first size using a laser cutting tool. The cutting briquette is metallurgically, mechanically, or both metallurgically and mechanically bonded to a tool base to form a drilling tool.
系统和方法包括一种计算机实施的方法，可以用于由新的纤锌矿氮化硼(w‑BN)超硬材料制造钻井工具。对纯w‑BN粉末进行超高压高温操作，以合成具有大于纯w‑BN粉末的颗粒的第一尺寸的w‑BN和立方氮化硼(c‑BN)压块。该超高压高温操作包括将w‑BN粉末加压至约20吉帕的压力，以100℃/分钟的加热速率加热w‑BN粉末并且以50℃/分钟的冷却速率冷却w‑BN粉末。使用激光切割工具将压块切割成小于第一尺寸的第二尺寸。将切割压块以冶金方式、机械方式或以冶金方式和机械方式两者结合到工具基底上以形成钻井工具。
