Abstract
Disclosed is a family of lubricants which are paste mixtures of powdered metals and oils or greases. These lubricants can be applied to gears, bearings, etc. by simple brushing on spraying on due to their pasty texture. And their adherence and longevity provide adequate lubrication with periodic applications as infrequently as once per week. Further, these lubricants possess good high temperature, high pressure, and corrosion resistance characteristics.
Claims14
A lubricant, comprising:
- between 35 and 95 parts by weight of nickel;
- and
- between 5 and 65 parts by weight of fluids selected from the group consisting of silicon oil, mineral oil, naphthenic oil, paraffinic oil, lithium soap, polyglycol, silicate esters, vegetable oil, and fluorides;
- whereby said lubricant is a paste.
