Systems and methods of making an enhanced vehicular brake rotor having improved wear and corrosion resistance are provided. The enhanced vehicular brake rotor comprises a brake rotor comprising a base comprised of iron (Fe). The base comprises an outer surface having open pores formed thereon. The rotor has a steam-treated layer formed on the outer surface and in the open pores. The steam-treated layer is comprised of iron oxide (FeO) and has a thickness of between 10 and 50 microns for enhanced wear and corrosion resistance to define the enhanced vehicular rotor.
