Even low concentrations of fine dust can be harmful to health. Fine dust is caused by wear and tear on brakes, tires, clutches and road surfaces. More than half of the fine dust from road traffic can be attributed to the braking process, or more precisely the wear of brake disks, brake shoes and tires. In the future, high-speed laser  metal  deposition will be used to coat Euro7-compliant, low-wear brake disks. Brake disks coated in this way emit far less fine dust than conventional brake disks.  The process not only ensures less fine dust, but also less wear.  The brake disk is usually coated with two layers. The first layer primarily serves as an anticorrosive agent and is usually comprised of stainless steel and nickel-free steel. The second layer consists of a mixture of hard carbides such as titanium carbide or tungsten carbide and a steel.  Electric vehicles can also benefit from this coating technology in the future, as the energy recovery process during braking means that disk brakes are rarely used. As a result, the brake disk can oxidize or even corrode, which leads to a loss of braking performance and, in extreme cases, may require premature replacement. High-speed laser metal deposition of oxidation- and corrosion-resistant materials on electric vehicle brake disks can counteract this risk.
