CYCLEN FRICTION MODIFIERS FOR BOUNDARY LUBRICATION

摘要

Compositions comprising an oil component and one or more cyclen compounds which can be structurally modified to affect anti-friction and anti-wear functionality. A method of using a cyclen compound to reduce boundary lubrication friction, comprising: providing opposed, first and second metal metal substrates; applying an oil-cyclen composition to at least one of said metal substrates; and contacting said first and second metal substrates, said contact inducing boundary lubrication friction therebetween, said composition in an amount sufficient to reduce boundary lubrication friction between said substrates, said reduction compared to boundary lubrication friction induced by substrate contact with application of a composition absent from said cyclen compound.
