Less CO2 and Fine Dust Emissions in Automotive: High-power laser cladding as a cost-effective rotor coating solution

There is increasing pressure on the automotive industry for further reduction of CO2 and particulate (PM10, PM2.5) emissions. One of the main issues is the fine dust resulting from the wear of the brake disc/brake pads, which is considered to be a major source of non-exhaust traffic-related emissions, particularly in urban locations. Carbide coatings are the state-of-art solution for controlling rotor wear. The challenge of cost-effective serial production for automotive applications can be mastered by high power laser cladding. © 2020 Wiley-VCH GmbH.
