Abstract
An ultrafine particle copper, tin, nickel, zinc lubricant with a surface area of from 5 to 70 m.sup.2 /g and a particle size of from about 0.01 to about 0.5 .mu.m. The powder dispersed in a carrier to form a dispersion stabilized by Brownian movement.
Claims22
A lubricating system comprising a particulate metal alloy selected from the group consisting of copper-nickel-tin, copper-nickel-tin-zinc and mixtures thereof and a carrier, said particulate metal alloy having a particle size of from about 0.01 to about 0.5 .mu.m and a surface area of from about 5 m.sup.2 /g to about 70 m.sup.2 /g, said particulate metal alloy being dispersed in said carrier in an amount of from about 0.1 to about 30% by volume.
A lubricating system comprising a liquid carrier;
- and from about 0.1 to about 30% by volume of a particulate copper-nickel-tin-zinc alloy having a particle size of from about 0.01 to about 0.5 .mu.ms and a surface area of from about 5 to about 70 m.sup.2 /g whereby said lubricating system is stabilized by Brownian movement for forming an at least partly colloidal suspension.
A powder lubricant comprising a copper-nickel-tin-zinc alloy having a mean particle size from about 0.01 to about 0.5 .mu.ms and a surface area of from about 5 to about 70 m.sup.2 /g.
