Specific applications of black silicon carbide as wear-resistant filler
–
Main applications
Wear-resistant flooring and anti-slip coating
When Black silicon carbide is added to industrial floors, ramps, docks, swimming pools, and other surfaces, it significantly improves wear resistance and anti-slip properties, and extends service life.
Mechanical seals and bearing components
Black silicon carbide is added to ceramic or metal matrices as a filler to manufacture mechanical seal rings, bearings, etc., to improve wear resistance and high-temperature dimensional stability. It is suitable for rotating equipment such as oil and chemical pumps.
Pipe and equipment lining
Black silicon carbide is used as lining for wear-resistant pipes, hydrocyclones, ore buckets, pump rooms, etc., to resist the erosion of high-speed fluids or particles, with a service life that can be 5–20 times that of cast iron or rubber.
Engines and aircraft components
Black silicon carbide can be coated on the surface of cylinder blocks, turbine impellers, etc., or added as a reinforcing phase to metal matrix composites (such as aluminum-based and magnesium-based) to improve wear resistance and high temperature resistance.
Electronic heat dissipation materials
Utilizing black silicon carbide’s high thermal conductivity (approximately 10–14 times that of clay bricks), it can be used as a filler in thermal grease, LED packaging, power module substrates, etc., to optimize thermal management.
Refractory materials and high-temperature structural components
Black silicon carbide is dded to refractory bricks and castables, it is used in high-temperature environments such as steel smelting furnaces and cement kilns to improve thermal shock resistance and wear resistance.
Self-lubricating and lubricating oil additives
Black silicon carbide micro powder is added to lubricating oil as a solid lubricant to reduce friction and wear.
Aerospace and Armor Materials
Black silicon carbide is used in erosion-resistant components such as rocket nozzles and turbine blades, as well as lightweight composite armor reinforcement materials.
Summary of key advantages of black silicon carbide
