摘要： A method to manufacture an automobile vehicle engine aluminum piston, comprises: printing an aluminum piston crown portion including an additive manufacturing (AM) piston crown work piece using initial aluminum powders defining an initial aluminum powder bed; removing the aluminum piston crown portion from the initial aluminum powder bed; fixedly joining a cast iron ring carrier to the AM piston crown work piece; placing the aluminum piston crown portion together with the cast iron ring carrier into a secondary and a tertiary aluminum powder bed; and printing a piston skirt integrally connected to the AM piston crown work piece and to the cast iron ring carrier.

摘要： 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.

摘要： 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.
