Green Silicon Carbide Micro-powder is a high-performance abrasive and reinforcing material. It has important applications in the field of friction materials due to its high hardness, high temperature resistance, good thermal conductivity, and strong chemical stability. The following is a summary of its application in friction materials and key information:
I. Characteristics of Green Silicon Carbide Micro-powder
1. Physical properties
– High hardness: Mohs hardness is 9.5, second only to diamond, which can significantly improve the wear resistance of friction materials.
– Good thermal conductivity: Rapid heat dissipation, reducing the risk of thermal decay of friction materials at high temperatures.
– High temperature resistance: Stable performance below 1400℃, suitable for high temperature conditions.
2. Chemical properties
– Acid and alkali corrosion resistance, strong oxidation resistance, and not easy to fail after long-term use.
II. Application in friction materials
1. Main function
– Enhance friction coefficient: Embedded as hard particles in the friction material matrix, improve the roughness of the friction interface, and enhance braking or transmission efficiency.
– Improve wear resistance: reduce material wear at high speed and high load, and extend service life.
– Improve thermal stability: inhibit the softening of the base material at high temperature to avoid performance degradation.
2. Typical application scenarios
– Automobile brake pads: used to improve braking performance and resist thermal decay.
– Industrial clutch plates: enhance the durability and reliability of the transmission system.
– High-speed rail/aviation brake materials: meet the high stability requirements under extreme working conditions.
