cubic boron nitride การใช้

• Cubic boron nitride has a crystal structure analogous to that of diamond.
• Common materials for tips include tungsten carbide, polycrystalline diamond, and cubic boron nitride.
• Low-pressure deposition of thin films of cubic boron nitride is possible.
• :Cubic boron nitride is a strong contender ( although it doesn't surpass diamond ).
• Cubic boron nitride seems to be hard enough, and does appear to be used in grinding wheels.
• Wentorf followed up in 1957 with his creation of Borazon, or cubic boron nitride, a material not found in nature.
• The highly compressed molecular structure resembled that of cubic boron nitride, the second-hardest of all known substances, exceeded only by diamond.
• He is best known as the inventor of cubic boron nitride ( trade name, " Borazon " ), the second-hardest material known.
• ,boron carbide is the third hardest substance known, after diamond and cubic boron nitride, earning it the nickname " black diamond ".
• The intrinsic group includes diamond, cubic boron nitride ( c-BN ), carbon nitrides and ternary compounds such as B-N-C, which possess an innate hardness.
• We think that this stuff will prove to be as hard as cubic boron nitride, and as good a conductor of heat as diamond,
• Any abrasive material may be used to create a honing stone, but the most commonly used are corundum, silicon carbide, cubic boron nitride, or diamond.
• The production method of this material does not involve high pressures as with other hard synthetic materials, such as cubic boron nitride, which makes production cheap.
• They can be made out of stainless steel or other neutron window materials such as zirconium, chromium, silicon carbide or cubic ( cubic boron nitride ).
• This was possible, as moissanite is one of the hardest substances known, with a hardness below that of diamond and comparable with those of cubic boron nitride and boron.
• Cubic boron nitride is insoluble in iron, nickel, and related alloys at high temperatures, but it binds well with metals due to formation of interlayers of metal borides and nitrides.
• Cubic boron nitride, among other applications, is used as an abrasive, as it has a hardness comparable with diamond ( the two substances are able to produce scratches on each other ).
• It is comparable with corundum ( ?-) in hardness and can only be polished and finished with abrasives of superior hardness such as cubic boron nitride and diamond powder, wheels, and compounds.
• When compared with other ceramic materials such as cubic boron nitride, silicon nitride, and aluminum oxide, PCD shows many better characteristics, including a high level of hardness and a relatively low coefficient of friction.
• Abrasive saws can also use superabrasive ( i . e ., diamond and cubic boron nitride or CBN ) blades, which last longer than conventional abrasive materials and do not generate as hazardous particulate matter.
