Abstract:
Systems and methods of making an enhanced brake rotor having enhanced wear resistance are provided. The systems and methods provide a vehicular rotor comprising a base comprising iron (Fe). The base comprises an outer surface having a laser-hardened portion thereon. The laser-hardened portion comprises martensite and having a thickness of between 10 and 100 microns of the outer surface to define the enhanced brake rotor with enhanced wear resistance.
