Title: Improvements in or relating to alloy articles
IPC: C22C1/04
Filed: 1924-01-07
Abstract: 216,484. General Motors Research Corporation, (Assignees of Williams, H. M.). May 22, 1923, [Convention date]. Metals, powdered, obtaining coherent masses from; metal bodies, porous.-A bearing bushing or lining is produced by mixing a finely-divided metallic compound with finely-divided alloyable metals, one at least of the components of the metallic compound being different from the alloyable metals, compressing the mixture to the desired form under high pressure, and heating the formed article in carbonaceous packing to a temperature sufficient to cause alloying of the alloyable metals. The metallic compound used is preferably formed by melting together equal proportions of tin and antimony, but compounds of copper and tin or copper and antimony may be used. A suitable mixture is composed of 77 parts of copper, 4.5 parts of tin, 13.5 parts of antimony-tin compound, and 5 parts of graphite. The product formed from such a mixture comprises a matrix of bronze in which are embedded fine particles of the tin-antimony compound and the graphite. Due to the presence of air among the particles of the mixture and to the fact that the mixture is not fused, the product is somewhat porous and will absorb oil. The porosity may be increased by including in the mixture a volatile material such as salicylic acid. Ammonium chloride may be added to facilitate the alloying action and lead may be added to form a softer matrix. Specifications 210,063, 214,580, and 230,896 are referred to.
