Definitions

  • the invention pertains to the art of lubricants, and more particularly to anti-galling compounds for bearing or threaded objects that are subjected to elevated temperatures.
  • Anti-galling compositions containing solid lubricants such as nickel and graphite are well known in the art as useful on various metal surfaces at elevated temperatures. These compositions are generally oil based and tend to migrate once applied, thus creating imprecise application and inconvenient and messy handling. Because these compositions tend to migrate, they often come in contact with areas of a part which should be kept free of lubricating materials. The use of these compositions on numerous applications where cleanliness, precision and speed are required, is precluded due to their unmanageable nature. In many other types of applications, the lubricating process becomes very time consuming and tedious to minimize the migration of the composition to undesired regions on a part.
  • the oil based compounds are also inconvenient to store, use and apply.
  • the oil based compounds are liquid compounds that are inconvenient and messy to apply to a component in a desired amount.
  • the liquid components of the oil based compound also tend to settle and separate out over time thereby requiring the liquid compound to be throughly mixed prior to use.
  • the component separation can also lead to the liquid compound prematurely drying in its container thereby making the compound unusable.
  • the compound cannot be applied to an apparatus or device that is hot, thus requiring extended down time for cooling prior to application.
  • the oil components can flash when exposed to high temperature environments.
  • the oil based compounds must be properly sealed to prevent them from prematurely drying and becoming unusable.
  • the liquid compounds also require a brush to apply the compounds to a part. After application of the liquid compound, the brush or applicator must be cleaned or be deposed of, thereby increasing the time and/or cost of using such compounds.
  • the lubricated part can then be secured to an apparatus or device.
  • both of these lubricants reduce migration problems associated with traditional lubricants, the lubricants require special application procedures prior to use, thus reducing the versatility of such compounds and increasing the cost of using such compounds.
