Abstract
Official abstract text for this publication.
A method of producing a Pb-free copper-alloy sliding material containing 1.0 to 15.0% of Sn, 0.5 to 15.0% of Bi and 0.05 to 5.0% of Ag, and Ag and Bi from an Ag—Bi eutectic. If necessary, at least one of 0.1 to 5.0% of Ni, 0.02 to 0.2% P, 0.5 to 30.0% of Zn, and 1.0 to 10.0 mass % of at least one of a group consisting of Fe 3 P, Fe 2 P, FeB, NiB and AlN may be added.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a Pb-free sintered copper-alloy sliding material, comprising: preparing a copper alloy powder consisting of, by mass percentage, 1.0 to 15.0% of Sn, 2 to 10% of Bi and 0.05 to 5.0% of Ag, with the balance being Cu and unavoidable impurities; heating said copper alloy powder to a temperature in a range of 700 to 900 degrees C.; and, cooling said copper alloy, in which said Sn, Bi and Ag are dissolved in solid copper alloy, und…
