  • Composite casting of bearing alloys to bushes
    Patent number: 4932460
    Abstract: Bearing alloy is applied to a bush (10) by mounting the bush (10) on a support structure (14) having an upstanding mandrel (17) so as to form an annular interspace (20) for reception of the bearing alloy in liquid form. The mandrel (17) projects above the bush (10) and has certain predetermined minimum dimensions. Infrared heating is applied to the bush (10) and the mandrel (17) sufficient to prevent the liquid bearing alloy freezing on contact with any of the surfaces defining the interspace (20). After degassing the liquid alloy is controllably cooled by coolant applied to the exterior of the bush (10) and finally the metalled bush is freed from the support structure (14).
