  • Composite brake rotor
    Patent number: 11927231
    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.
    Type: Grant
    Filed: July 12, 2022
    Date of Patent: March 12, 2024

  • Manufacturing of aluminum piston with cast iron ring carrier using powder bed fusion method
    Patent number: 11821384
    Abstract: 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.
