SUSTAINABLE TECHNOLOGY: LASER CLADDING OF BRAKE DISCS REDUCING ITS PARTICULATE MATTER EMISSIONS

Abstract

The emission of 2.5µm particulate matter (PM2.5) from braking systems poses a significant health hazard. The wear of brake discs contributes to this issue. However, it can be mitigated. In this paper, a brake disk was Nickel laser cladded. Resulting in an improvement of more than 5 times of coefficient of friction and wear resistance. Likewise, under the deduced mathematical model, this improvement brings an estimative of annual reductions of 230,000 metric tons of PM2.5 not emitted; and more than 400,000 deaths, resulting from these emissions, avoided.
