Abstract
A brake rotor having a composite structure may include an annular body defining opposite friction surfaces of the brake rotor. The annular body may include a core made of an Al—Si alloy, a thermal barrier layer made of a thermally insulating material disposed on the core, and a wear-resistant layer made of an Fe—Al—Si—Zr alloy disposed on the core over the thermal barrier layer. The wear-resistant layer may define a first one of the opposite friction surfaces of the annular body.
