1. A method of manufacturing a brake rotor or brake drum having a composite structure, the method comprising:
casting an aluminum alloy to form a core of the brake rotor or brake drum, the core defining a core surface;
depositing a high entropy alloy or yttrium stabilized zirconia on the core surface to form a thermal barrier layer on the core surface; and
depositing an iron-aluminum-silicon-zirconium alloy on the thermal barrier layer to form a wear-resistant layer on the thermal barrier layer, the wear-resistant layer defining a friction surface of the brake rotor or brake drum.
