  • Method of heat treating bearing materials
    Patent number: 4734967
    Abstract: An improved method of producing a powdered metal aluminum base bearing material is provided. A bearing strip composed of three layers of sintered aluminum base particles which has been roll clad to a rigid backing layer is subjected to a heat treatment procedure in a continuous manner at a temperature of from about 700.degree. F. to about 900.degree. F. for at least thirty seconds and then cooled at a rate of at least 100.degree. F./hr. Bearings made from the resulting material show dramatic fatigue life improvement in comparison to that obtainable with currently available powdered metal aluminum bearing materials.
