Overview of superfine cubic boron nitride cbn powder for electroplated tools
Boron Carbide (B4C) is a ceramic compound renowned for its exceptional hardness and wear resistance, ranking just below diamond and cubic boron nitride in terms of hardness. Composed of boron and carbon atoms arranged in a covalently bonded crystal structure, it exhibits unique physical and chemical properties that make it highly valuable in various industrial and military applications. Boron carbide’s high melting point, low density, neutron-absorbing capability, and extreme toughness further distinguish it among advanced materials.
Features of superfine cubic boron nitride cbn powder for electroplated tools
-
Extreme Hardness: With a Mohs hardness of around 9.3 to 9.5, boron carbide is one of the hardest materials known, surpassed only by diamond and cubic boron nitride.
-
Lightweight: Despite its hardness, boron carbide has a relatively low density of about 2.52 g/cm³, which makes it an attractive material for lightweight armor systems.
-
Thermal Stability: It possesses excellent thermal stability, maintaining its properties up to temperatures around 2,000°C, making it suitable for high-temperature applications.
-
Neutron Absorption: Boron carbide is a potent neutron absorber due to its boron content, making it ideal for nuclear shielding and control rods.
-
Chemical Resistance: Resistant to most acids and alkalis, except for hydrofluoric acid and hot concentrated alkaline solutions, ensuring durability in corrosive environments.
-
Abrasion Resistance: Its exceptional wear resistance makes it suitable for applications where friction and abrasion are prevalent, such as sandblasting nozzles.

Parameters of superfine cubic boron nitride cbn powder for electroplated tools
Superfine cubic boron nitride (CBN) powder can be used for electroplating tools, and the parameter values for its usage will depend on several factors such as the application, plating process, and tool type.
For general purposes, CBN powder has a hardness of around 97-102, which is higher than conventional carbon carbide powders. This makes it an excellent choice for applications that require high or wear resistance, such as cutting tools, drill bits, and fixtures.
In terms of plating process, super fine CBN powder is commonly used in combination with other materials to form an even more durable coating. The thickness of the CBN layer depends on the applied voltage and the frequency of the current being passed through the tool. Generally speaking, a thickness of at least 5 microns is desirable for optimal electrical and wear resistance.
Finally, the tool type may also impact the choice of CBN powder. For example, carbide-based cutting tools such as diamond-tipped and high-speed steel drills may require a different type of CBN powder that has a lower grain size and better chemical stability.
Overall, CBN powder can be an effective choice for electroplated tools due to its high hardness, good wear resistance, and compatibility with various plating processes. However, specific parameters such as particle size, composition, and treatment method should be carefully considered depending on the intended use of the tool.
