New Process Based on Rotate System and Ehla Laser Cladding Parameters for Nickel Automotive Brakes

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.
