More Information
Summary:The disclosed technology generally relates to coatings, and more particularly to metallic alloy coatings for rotors having nanocrystalline grains. In one aspect, a brake rotor comprises a disc-shaped friction area and a coating having a metallic alloy composition formed on the friction area to form a friction surface configured to contact a brake pad. The metallic alloy composition comprises Fe, Cr, B, C, Mn, Si and Mo as alloying elements that are present at concentrations exceeding impurity concentrations, and wherein the coating comprises nanocrystalline grains having an average grain size less than 100 nm.
