N2 - Latest development in high-power lasers made possible a wide variety of laser surface modifications. Such surface modifications include: glazing, shock peening, alloying, cladding and texturing. The main reason behind applying these treatments is to improve the tribological performance of the modified surfaces. In addition to reducing friction and wear, it is favorable to improve the scuffing resistance. Scuffing can be defined as a sudden catastrophic failure of a lubricated sliding surface characterized by a sudden rise in friction; resulting in severe surface damage through localized plastic flow. This paper investigates friction and scuffing performance of laser glazed 1080 steel and laser textured H13 stainless steel. Results showed that laser glazed surfaces reduced sliding friction under dry conditions by approximately 35% and improved wear resistance. In addition, laser glazed surfaces showed high resistance to scuffing compared to unglazed surfaces. Also, Laser surface texturing technique reduced sliding friction under lubricated conditions and improved scuffing resistance.
