Definitions

  • Embodiments and aspects of the present invention relate to tin based white metal alloys useful in various industrial applications, including the bushings of rolling mill oil film bearings.
  • ASTM #2 The most prominent white metal alloy used in oil film bearings in the rolling mill field is described in ASTM B23 #2, (referred to here as ASTM #2) and is comprised primarily of tin, with antimony and copper, as alloying elements. ASTM #2 is well understood and is readily deposited onto bushing shells via centrifugal casting, spray deposition, or welding. Unfortunately, ASTM #2 has relatively low fatigue resistance, which limits load capacity of bearings made with this material.
  • Nickel hardened white metal alloys have been used where common versions are referred to as Tuftin. These alloys can be cast and welded, but they contain Nickel, which is a heavy metal that is undesirable for environmental reasons.
  • U.S. Pat. No. 4,140,835 (Goddard) and U.K. Application No. 2146354 A disclose cobalt as a component of tin based white metal alloys that also include cadmium.
  • Cadmium is a known carcinogen that has been banned from most workplaces and thus is undesirable.
  • U.S. Pat. No. 4,795,682 discloses a tin/cobalt alloy useful as a sacrificial coating designed to absorb particulates. Such coatings lack the toughness required for heavily loaded oil film bearing applications, and the disclosed use of cobalt at elevated percentage levels would inhibit the flow characteristics necessary in a casting or welding process.
  • aspects of the present invention relate to a tin based white metal alloy that is universally useful in centrifugal casting, spraying, and welding applications.
  • aspects of the present invention also relate to a tin based white metal alloy having the elevated strength and fatigue resistance required for use in heavily loaded oil film bearings of the type commonly found in the metals industry.
  • aspects of the present invention further relate to a tin based white metal alloy that is low in toxicity and generally free from carcinogenic components, including cadmium and the like.
  • aspects of the present invention may be achieved by replacing zinc and silver components of the alloy disclosed in the above referenced U.S. Pat. No. 6,589,372 B1 with cobalt in amounts ranging between about 0.1%-0.7% by weight, with amounts ranging between 0.2% and 0.5% being considered optimal.
  • FIG. 1 is a graph of laboratory test data comparing the alloy of the present invention with commonly used alloys in the Field.
  • Embodiments of the present invention are not limited to use in the described systems.
  • a tin based white metal alloy in accordance with the present invention includes as principal components tin, antimony, and copper, to which cobalt has been added. Addition of cobalt in amounts above approximately 0.7% by weight has been found to disadvantageously lower the fluidity of the resulting alloy. Thus, cobalt additions of between about 0.1%-0.7% by weight have been found to be effective in achieving the above-stated objectives, with additions of between about 0.2%-0.5% by weight being optimal.
  • Tin based white metal alloys of the present invention consist essentially of the components listed in the following examples:
  • alloys of the present invention may be centrifugally cast, and may also be drawn into wire for use in spraying or welding applications. Further, alloys of the present invention have the strength and fatigue resistance required for use in heavily loaded bearing applications, including the steel making industry applications, while being free of components that either are banned or otherwise detrimental.
  • Fatigue resistance of white metal alloys can be determined experimentally through the use of tension/compression specimens that are cycled until failure. Laboratory test data comparing the alloy of the present invention with commonly used alloys in the field are illustrated in FIG. 1 . Based on test data the fatigue strength of the alloy containing 0.3% to 0.5% cobalt has excellent fatigue resistance, exceeding that of other alloys commonly used in the rolling mill application. Test data shown was determined in accordance with ASTM E 466 with an applied load of 7,500 psi (51.7 MPa) and test frequency of 10 Hz.
