Abstract

A sintered compact comprising lead oxide and a matrix of a metal such as copper or silver with a free energy of oxide formation which is more positive than lead oxide is formed by pressing and sintering a powder mixture of the components. Additives such as SiO2, Al2O3, Bi2O3, CrO3, V2O5, As2O5, MoO3, WO3, Sb2O3, B2O3, TiO2, SnO2, P2O5, Fe3O4 and Cu2O may also be included and the oxide content preferably constitutes 5-20% by weight of the compact. The copper or silver powder is preferably mixed with a lubricant such as stearic acid prior to blending with the lead oxide and the compacted mixture may be preoxidized by heating to 700-1000 DEG F. prior to sintering in a non-reducing atmosphere such as argon or nitrogen at 1400-1700 DEG F. The sintered body may also be heated in an oxidizing gas to reoxidize any reduced lead and finally coined to final size, shape and density. Alternatively the powder may be sintered in a reducing gas and then re-oxidized. In another embodiment a steel backing strip plated with copper or silver is coated with the powder mixture, the composite is preoxidized, sintered, rolled to a density of 80-95% of theoretical and then resintered at 1400-1700 DEG F. It is finally vacuum impregnated with a lubricant to form a sintered rubbing material for use as bearings, piston rings, seals and clutch plates. Specification 963,266 is referred to.
