Corundum, a hard and durable mineral, has found significant applications in the production of brake linings. Brake linings are crucial components in braking systems, responsible for generating the necessary friction to slow down or stop a moving vehicle. The use of corundum in brake linings is mainly due to its unique properties that can enhance the performance of brake linings friction materials.

Corundum contributes to the high friction stability of brake linings mixes. When incorporated into the brake linings mixture, it helps maintain a consistent friction coefficient over a wide range of operating conditions. This is essential for ensuring reliable braking performance. Whether the brakes are applied gently or forcefully, the presence of corundum ensures that the friction between the brake lining and the brake disc remains stable, providing a smooth and effective braking experience.

One of the most notable advantages of corundum in brake linings is its excellent wear resistance. Brake linings are subject to continuous wear and tear during braking operations. Corundum’s hard nature makes it highly resistant to abrasion, which significantly extends the lifespan of the brake linings. This not only reduces the frequency of brake lining replacements but also improves the overall safety of the braking system as worn – out brake linings can lead to reduced braking efficiency.

Corundum can withstand high temperatures without significant degradation. During braking, a large amount of heat is generated due to the friction between the brake linings and the brake disc. Corundum in the brake linings can endure these high – temperature conditions, maintaining its structural integrity and performance. This thermal stability helps prevent the brake linings from fading at high temperatures, ensuring consistent braking performance even under extreme conditions.

One of the main drawbacks of using corundum in brake linings production is its relatively high cost. Mining, processing, and refining corundum into a form suitable for use in brake linings require significant resources and energy, which drives up the cost. This high cost can make brake linings more expensive for consumers, and may also limit the use of corundum – based brake linings in some cost – sensitive applications.

In some cases, the use of corundum in brake linings may lead to increased noise generation during braking. The hard particles of corundum can cause vibrations and impact – like noises when in contact with the brake disc. Although manufacturers are constantly working on minimizing this issue through various techniques such as adjusting the formulation of the brake linings mixture and optimizing the manufacturing process, it still remains a potential drawback.

In conclusion, while corundum offers many advantages in terms of improving the performance of brake linings friction materials, its high cost and potential for noise generation are factors that need to be carefully considered in the production of brake linings.
