Application of boron nitride

Cubic boron nitride grinding tools have excellent grinding performance, which not only can complete the processing of brutal to-grind materials, improve productivity, and effectively improve workpiece grinding quality but also can strictly control the shape and size of the workpiece, improve the surface integrity of the workpiece after grinding, thereby improving the fatigue strength of the parts and extending their service life. Cubic boron nitride micro powder suits bonding systems such as resins, metals, ceramics, etc. It can also be used to produce polycrystalline composite sheets and can also be used as loose abrasive particles, grinding paste, etc. Cubic boron nitride has long service life and good wear resistance as a grinding tool material. However, monocrystalline cubic boron nitride also has shortcomings, such as small grain size, anisotropy, and cleavage surfaces prone to cleavage. Due to the many performance advantages of cubic boron nitride, its production process has less energy consumption and environmental pollution than other superhard materials. Therefore, using cubic boron nitride significantly contributes to metal grinding, leading to revolutionary changes in grinding, and is the second leap in grinding technology. Manufacturing of alloys, high-temperature resistant materials. Semiconductor. Nuclear reactor. Lubricant. The boron nitride, usually produced by production and editing, is a graphite-type structure known as white graphite. The other is the diamond type, similar to the principle of converting graphite to diamond. Graphite-type boron nitride can be converted to diamond-type boron nitride at high temperatures (1800 ℃) and high pressures (8000Mpa) [5-18GPa]. It is a new high-temperature-resistant superhard boron nitride material for making drill bits, abrasives, and cutting tools. Boron nitride has corrosion resistance, excellent electrical insulation, and a specific resistance more significant than 10-6 Ω. cm; The compressive strength is 170 MPa; The coefficient of thermal expansion in the c-axis direction is 41e-6/℃ and in the a-axis order is – 2.3e-6; The operating temperature is 900 ℃ in an oxidizing atmosphere, while it can reach 2800 ℃ in an inactive reducing atmosphere. However, the lubricating performance is poor at room temperature.
