Abstract

The whole world depends on land vehicles such as trucks, cars and motorcycles to meet essential demands. As a result, PM2.5’s emissions become to centre attention; being that, 20% comes from brake-disc and pad friction. In view of this problem, this paper presents a new method for brake-discs laser cladding; using nickel (coating) and rotation system. To this end, was used the high-speed laser application system (EHLA); consisting of: an ytterbium laser, robotic arm, rotating shaft with stepper motor and coat powder aspersion system. The results shown a viability of this technique. With the following parameters: tangential velocity of scanning “vs” 9-11mm/s, power efficiency “E” of 70-75% and deposition rate “µ” of 4g/min. Producing homogeneous, well-anchored coatings. With high densification.
