Simulation of thermal and mechanical performance of laser cladded disc brake rotors

Disc brakes wear during braking events and release airborne particulates. These particle emissions are currently one of the highest contributors to non-exhaust introduce health hazards as well environmental contamination. To reduce this problem, corrosion-resistant disc coatings have been implemented on grey cast iron brake rotors by using various deposition techniques such thermal spraying overlay welding. High gradients risks flaking off cracking thermally sprayed with adhesive bonding substrate. Overlay welding laser cladding offers metallurgical coating substrate other benefits that motivate a candidate for discs. This study aims investigate effect thermo-structural performance coated Therefore, thermo-stress analysis COMSOL Multiphysics 5.6 software is performed discs non-coated – reference stainless steel consumables. The Results demonstrated surface temperatures were more localised, overall higher in cladded over three times stresses attained output simulations has compared tests found literature. Laser presented reliability performance, nonetheless requiring evaluation its impact system components.
