“…Performances on vehicle and impact on its behaviour have also been verified on test track and in real driving conditions with the same level of collection performances. The total number concentration of the PM was found by Mulani et al [ 230 ] to be inversely linked to the disc’s thermal conductivity, with the highest concentrations seen in friction pair with ceramic discs. The thermal conductivity of the disc is a crucial parameter in the brake pad design process.…”

Airborne particulate matter (PM) is a pollutant of concern not only because of its adverse effects on human health but also on visibility and the radiative budget of the atmosphere. PM can be considered as a sum of solid/liquid species covering a wide range of particle sizes with diverse chemical composition. Organic aerosols may be emitted (primary organic aerosols, POA), or formed in the atmosphere following reaction of volatile organic compounds (secondary organic aerosols, SOA), but some of these compounds may partition between the gas and aerosol phases depending upon ambient conditions. This review focuses on carbonaceous PM and gaseous precursors emitted by road traffic, including ultrafine particles (UFP) and polycyclic aromatic hydrocarbons (PAHs) that are clearly linked to the evolution and formation of carbonaceous species. Clearly, the solid fraction of PM has been reduced during the last two decades, with the implementation of after-treatment systems abating approximately 99% of primary solid particle mass concentrations. However, the role of brown carbon and its radiative effect on climate and the generation of ultrafine particles by nucleation of organic vapour during the dilution of the exhaust remain unclear phenomena and will need further investigation. The increasing role of gasoline vehicles on carbonaceous particle emissions and formation is also highlighted, particularly through the chemical and thermodynamic evolution of organic gases and their propensity to produce particles. The remaining carbon-containing particles from brakes, tyres and road wear will still be a problem even in a future of full electrification of the vehicle fleet. Some key conclusions and recommendations are also proposed to support the decision makers in view of the next regulations on vehicle emissions worldwide.

“…The brake shoes are pressed on the braking drum by the cylinder, slowing the wheel. A vehicle's engine braking system is responsible for the following operations: [8]  For automobiles, having a reliable braking system is essential for coming to a stop in the shortest feasible space. Energy from the vehicle's motion is transformed into heat to accomplish this.…”

“An object remains in its state of rest or in motion until and unless acted upon by an external force” Newton’s first law of motion, Braking systems were made possible by this rule of Sir Isaac Newton, which states that the greater the vehicle’s speed, the greater the brake force needed to slow it down. This idea spawned several studies in the subject of braking, leading to its development, which in turn has given us the luxury of picking the most effective braking system for any given situation. This research analyses the thermomechanical behaviour of dry disc-to-pad contact during braking using Finite Element Analysis (FEA). Air ventilation and friction will be increased by modulating the design for disc heating issue due to long life of brake disc. The modeling of transient disc brake temperature is used to determine the disc’s geometric design for vehicle ventilation. The thermal-structural analysis is coupled to calculate disc deformation, Von Mises stress, as well as pad contact temperature distribution. The findings match the specialist literature.

“…The braking system plays a crucial role in ensuring the braking efficiency and stable operation of high-speed trains. [1][2][3] The coordination between brake disks and brake pads directly influences the coefficient of friction (COF) and wear performance of the system. The friction counterparts experience severe service conditions during emergency braking, especially in high-speed conditions and in a detrimental atmosphere.…”

The current steel brake disk and Cu‐based powder metallurgy brake pad used in high‐speed trains suffer fading coefficient of friction (COF) and excessive wear, resulting in a shorten lifetime and numerous exhausted brake disks. High‐velocity oxygen fuel (HVOF) spray‐prepared coatings have proven their ability to improve COF and decrease wear rate. In this article, Cr3C2‐NiCr coating was sprayed on a steel brake disk, and a series of emergency braking tests under dry and wet conditions were performed on a subscale brake dynamometer, to comprehensively evaluate the braking performance of coated brake disk. The results showed that the coated brake disk exhibits a higher COF at 380 km/h, which effectively inhibits the COF fade compared to the steel brake disk case. The coated brake system also achieves a lower wear rate of the brake pad at 380 km/h, showing the desired high COF and low wear rate properties of the braking system. Additionally, the coated brake disk maintained surface integrity even after severe braking tests, highlighting its potential in the braking system. Based on the characterizations of wear debris and brake pads, a harder and thinner oxide friction film plays a crucial role in achieving the excellent braking performance in coated brake disk cases.
