There is increasing pressure on the automotive industry for further redn. of CO2 and particulate (PM10, PM2.5) emissions. One of the main issues is the fine dust resulting from the wear of the brake disk/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 soln. for controlling rotor wear. The challenge of cost-effective serial prodn. for automotive applications can be mastered by high power laser cladding.
