Description
Patented on. 19, 1931 ALLOY Jeno Tanss, Petrolla, Pa, assignmto L. Sonneborn Sons, Inc., a. corporation of Delaware No Drawing. Applicationlilay 20, 1936, Serial ts. 80.78!
This invention relates to an alloy, and more particularly to an alloy bearing.
An object of the invention is to provide an alloy which is resistant to corrosion, and especially 5 to corrosion caused by oxidation products oi. lu-
bricating oils.
Cadmium-silver bearings have been proposed for use under relatively high speed, pressure and/or temperature. Such alloys have a high 10 melting point and mechanical strength, do not weaken and disintegrate as easily as other bearings, such as babbitt, and have a long working 7 life. These bearings are usually composed oi. at least 95% cadmium and up to 5% silver, and ii 15 desired, a small amount of a hardening metal. such as copper or nickel. However, they possess the serious disadvantage that they are corroded in use by oxidation products of a lubricating oil with which they come in contact, which greatly 20 reduces their life and eflieiency.
I have discovered that an alloy consisting predominantly of cadmium and containing small amounts oi silver and tin is not corroded by lubricating oils, and that the lite and emciency of 25 the same are greater than other cadmium-silver alloys. If desired, the alloy may also contain a hardening metal, such as copper or nickel.
A representative alloy the type mentioned An alloy of the following composition gives very good results:
Per cent Cadmium at least 95 40 Silver 1.75 to 2.5 l; Tln 0.1 w 3 Copper or nickel 0.25 to 0.5
Alloys of the above general composition have a melting point higher than ordinary babbitt bearings, are harder and tougher, retain their mechanical strength over a long period or use, and are not appreciably corroded by lubricating 5 oils over a long period oi! time. I
The invention has been described with respect to bearings, but. it is understood that it is not to be so limited, and covers broadly all alloys of the described composition for various uses. I am not to be limited to any details of the description, but only by the appended claims wherein I have endeavored to claim the inherent novelty.
I claim:
l. A bearing alloy containing 0.5 to 4.9% silver, 0.1 to 3% tin, and the balance substantially cadmium, said alloy being characterized by substantial non-corrosiveness against lubricating oils.
2. A bearing alloy containing 1.75 to 2.5% silver, 0.1 to 3% tin, and the balance substantially cadmium, said alloy being characterized by substantial non-corrosivene'ss against lubricating 9 3. A bearing alloy containing 0.5 to 3.9% silver, 0.1 to 3% tin, 0.25 to 1% of a hardening metal, and the balance'substantially cadmium, said alloy being characterised by substantial noncorrnsiveness against lubricating oils.
4. Abearing alloy containing 0.5 to 3.9% silver. so 0'.lto3% tin,0.25to 1% coppcnandthebaiance substantially cadmium, said alloy being characterised bysubstantial. non-corrosiveness against lubricating oils.
5. Abearing alloy containing 1:15 to 25%;11- ver, 0.1 to 3% tin, 0.25 to 0.5% copper, and the balance substantially cadmium, said alloy being characterised by substantial non-oorrosiveness against lubricating oils. o
