  • Method of manufacturing components made of dissimilar metals
    Patent number: 11267061
    Abstract: An article of manufacture comprises a first component having a first mating surface and a second component having a second mating surface. The first component may include an aperture having internal splines or gear teeth, and/or an outer perimeter having external splines or gear teeth. The first and second components are disposed such that a gap is provided between the first and second mating surfaces. Brazing material is disposed between the first and second mating surfaces so as to mechanically couple the first and second components. The first component may be made of a powdered metal or a non-powdered metal, and the second component may be made of the other of such two metals. In one embodiment, the first component may be a planetary carrier plate portion having internal splines and the second component may be a planetary carrier spider portion.
