  • Patent number: 10888928
    Abstract: A method of sinter fitting a powder metal compact around a core forms a composite component. By exploiting the shrinkage associated with the sintering of a powder metal compact, a sintered powder metal section may be dimensionally shrunk onto a core to create a mechanical interference fit between a core section and a sintered powder metal section. This method may be used to join materials such as aluminum and steel together, which traditionally have been difficult to join to one another.

  • Patent number: 10835866
    Abstract: The present disclosure describes hybrid binary catalysts (HBCs) that can be used as engine aftertreatment catalyst compositions, specifically 4-way catalyst compositions. The HBCs provide solutions to the challenges facing emissions control. In general, the HBCs include a porous primary catalyst and a secondary catalyst. The secondary catalyst partial coats the surfaces (e.g., the internal porous surface and/or the external surface) of the primary catalyst resulting in a hybridized composition. The synthesis of the HBCs can provide a primary catalyst whose entire surface, or portions thereof, can be coated with the secondary catalyst.
