A good braking system can make driving more precise. How to mix these materials together and how can the brake pads produced be able to withstand high temperature and friction performance? The science is processing.
Just like mixing cocktails, the processing principle of brake pads is to mix various materials together. In addition to the main materials that produce friction effects just introduced, interface materials must also be added to avoid side effects between various materials. Why do they occur? side effect? This is because the expansion coefficient, oxidation effect, and applicable temperature of each material are different. If a good interface is not used, when the temperature is low, the lower expansion material will invade the space of the unexpanded material. At this time, The interface material comes in handy. Its function is like the gin, lime juice and other bases used in bartending, which has the effect of centering and coordinating.
The basic processing method is mixing and imparting moderate temperature. A more advanced brake pad processing method is to process the basic materials through powder metallurgy, which can be mixed more finely and can withstand higher temperature and higher pressure smelting environments. Brake pads made of powder metallurgy are uniform in material, durable and long-lasting. They are currently the mainstream method for manufacturing high-performance modified brake pads. However, they are not common in the field of low-priced mass-produced cars that reduce costs.
