16586609 High Carbon Heat Resistant Brake Pads for BUICK CADILLAC

16586609 High-carbon heat-resistant brake pads are based on three-dimensional woven high-carbon carbon fibers, and use silicon nitride gradient coating and ceramic fiber composite reinforcement technology to increase the operating temperature threshold to above 850°C. At the same time, the fluctuation range of the friction coefficient is controlled within 5% in a low-temperature environment of -50°C, showing stable braking performance in all weather and all scenarios.

The friction layer of this product combines the carbon fiber preform with nano-silicon carbide particles through a chemical vapor deposition process to form a honeycomb porous structure with a porosity of only 1.8%, which is 60% higher than that of traditional high-carbon brake pads. In the surface gradient coating, the Mohs hardness of silicon nitride reaches 9.5, and the thickness is controlled between 80-120 microns, which not only prevents hard particles from scratching the brake disc, but also forms an aerodynamic effect on the friction interface through the micro-groove design, reducing the braking noise to below 42 decibels. It is worth noting that rare earth oxide modification technology is introduced in the product design. The synergistic effect of cerium oxide and lanthanum oxide not only reduces the high-temperature oxidation rate, but also achieves a stable dynamic friction coefficient range of 0.48-0.52 through the self-lubricating properties of rare earth elements, ensuring that the thermal decay rate is less than 7% after ten consecutive 100km/h emergency brakes.

The 16586609 brake pad adopts microwave assisted sintering technology, and the carbon fiber orientation is arranged by electromagnetic field at a high temperature of 1500℃, so that the longitudinal compressive strength exceeds 380MPa, and the transverse toughness is increased to 3 times that of traditional products. The back plate uses laser selective melting 3D printing technology, combining titanium aluminum alloy skeleton with topological optimization hollow design, reducing weight by 25% while increasing heat dissipation area by 40%. With the patented vortex guide groove design, the surface temperature of the brake disc can be reduced from 600℃ to 200℃ within 90 seconds. The product is suitable for electric supercars, heavy-duty trucks and special engineering machinery.
