| Description: |
• Determine the potential of laser glazing to lower parasitic energy losses between the flange and rail in rail transport. • Develop a fundamental understanding of the metallurgy associated with the formation of low-friction. surface layers during laser glazing processing, and how these layers reduce friction between rail and wheel. • Determine the potential of laser glazing to improve fuel efficiency and component durability/reliability of critical engine/powertrain components. • Evaluate the impact of friction stir processing techniques on the friction and wear of steel. Approach • Develop advanced laser glazing processes to form glazed regions on carbon steels. • Perform benchtop tests, full-scale rig tests, and field tests of glazed steels and rails to quantify the impact of glazing and friction stir processing on parasitic friction losses. • Characterize glazed and non-glazed steels to elucidate the impact of glazing and friction stir processing on the microstructure of steel (1080 steel). |
