Abstract
A vehicle braking component having a composite structure includes a brake core comprising an aluminum alloy, the brake core defining a core surface, a thermal barrier layer comprising a thermally insulating material, and an adhesion layer between the core surface and the thermal barrier layer to facilitate adhesion between the thermal barrier layer and the brake core. The adhesion layer includes a metal. The vehicle braking component includes a wear-resistant layer on the thermal barrier layer. The wear-resistance layer includes an iron-aluminum-silicon-zirconium alloy and defines a friction surface of the vehicle braking component.
