1. Preheating
Preheating is to eliminate residual stress inside the brake disc and ensure the uniformity of quenching temperature. The preheating temperature is usually around 600 ºC. The preheating time depends on the size and thickness of the brake disc, usually 1-2 hours.
2. Quenching
Quenching is the process of rapidly cooling the brake disc to form martensite on its surface, thereby increasing its hardness and strength. The quenching temperature is generally between 820~900 ºC, and the quenching medium can be water or oil. The cooling rate must be controlled within an appropriate range to avoid defects such as cracking and deformation.
3. Tempering
Tempering is to give the quenched brake disc a certain degree of toughness and tensile strength. The tempering temperature depends on the strength and hardness of the selected material, generally ranging from 300 to 650 ºC. Excessive tempering temperature can lead to a decrease in hardness and affect braking performance; Low tempering temperature can lead to increased brittleness.
4. Grinding
The surface of the brake disc that has undergone tempering treatment is relatively rough and needs to be ground to make its surface smooth and uniform. Grinding can be carried out through turning, grinding machines, grinding wheels, and other methods.

Good braking effect: The brake disc is clamped by the brake caliper to generate braking force, which can play a role in slowing down or stopping when stepping on the brake, and the braking effect is significant
Easy maintenance: The structure of the brake disc is relatively simple, easy to maintain and repair, and has good drainage performance, reducing brake failure caused by water or sediment
High frequency braking operation: The response of the disc brake system is agile, suitable for high-frequency braking operations, and meets the requirements of the ABS system
Balanced braking force: The braking force of the left and right wheels of disc brakes is relatively balanced, without the frictional assistance of drum brakes
Reduce brake decay: When continuously pressing the brake, disc brakes are relatively less likely to cause brake decay, which can lead to brake failure
Small size change: The change in size of the brake disc after heating will not cause an increase in the stroke of the brake pedal
Improving braking performance: Using carbon ceramic material for brake discs can greatly enhance their resistance to thermal degradation, shorten braking distance, and improve vehicle safety performance
