MILLING TOOLS FROM NEW WURTZITE BORON NITRIDE (W-BN) SUPERHARD MATERIAL
Systems and methods include a computer-implemented method can be used to make milling tools from new wurtzite boron nitride (w-BN) superhard material. An ultra-high-pressure, high-temperature operation is performed on pure w-BN powder to synthesize w-BN and cubic boron nitride (c-BN) compact having a first size greater than particles of the pure w-BN powder. The ultra-high-pressure, high-temperature operation includes pressurizing the w-BN powder to a pressure of approximately 20 Gigapascal, heating the w-BN powder at a heating rate of 100° C./minute and cooling the w-BN powder at a cooling rate of 50° C./minute. The compact is cut to a second size smaller than the first size using laser cutting tools. The cut compact is turbulently mixed with additives in a mixer under vacuum. The cut compact mixed with the additives is thermally sprayed onto a tool substrate to form the tool.
