Abstract
A mixture of metals composed predominantly of aluminum and the balance bearing phase materials are heated to a molten state, ejected through an orifice and atomized by impinging a stream of cold water against the molten metal to effect a rapid drop in temperature as well as solidifcation. A layer of the resulting pre-alloyed particles are roll compacted simultaneously with a sacrificial surface layer and a bottom bonding layer, both being composed of aluminum base particulate materials. The bottom layer is devoid of bearing phase materials. The tri-layer strip is sintered, roll clad onto a backing member and post-annealed, blanked and formed into a bearing which is bored to remove the sacrificial layer.
