Abstract
Method of lubricating a rubbed surface with a gaseous phase lubricant including a monomer constituent dispersed in a carrier fluid, where the monomer constituent is capable of forming in situ a polymer film directly on rubbing surfaces but is not polymerized in the carrier fluid, such that wear and friction of the rubbed surface are effectively reduced.
Claims19
A method of reducing wear, comprising the steps of:
- providing a first solid material having a first surface which will be exposed to rubbing contact with a second surface of a second solid material, wherein said first solid material and said second material are each independently selected from the group consisting of ceramic materials, metallic materials, and composite materials;
- contacting at least said first surface of said first solid material with a lubricating gaseous composition comprising monomers in a gaseous state dispersed in a carrier gas, wherein said monomers are selected from the group consisting of alkyl methacrylates, alkyl acrylates, vinyl esters, vinyl alkyl ethers, allyl esters of alkyl acids, allyl esters of aryl acids, diallyl esters of alkyl acids, diallyl esters of aryl acids, divinyl esters of alkyl acids, divinyl esters of aryl acids, triallyl esters of alkyl acids, triallyl esters of aryl acids, trivinyl esters of alkyl acids, and trivinyl esters of aryl acids;
- providing said rubbing contact between said first solid material and said second solid material in a manner subjecting said lubricating gaseous composition to tribological conditions whereby said lubricating gaseous composition reduces wear and friction of at least one of said first solid material at said first surface and said second solid material at said second surface exposed to rubbing contact.

- contacting at least said first surface of said first solid material with a lubricating gaseous composition comprising monomers in a gaseous state dispersed in a carrier gas, wherein said monomers are selected from the group consisting of diallyl phthalate, diallyl succinate, diallyl sebacate, triallyl trimesate, n-butyl methacrylate, hexyl methacrylate, lauryl methacrylate, n-octadecylmethacrylate, iso-decyl acrylate, n-butyl acrylate, hexyl acrylate, lauryl acrylate, n-octadecyl-acrylate, vinyl acetate, vinyl propionate, vinyl octoate, vinyl 2-ethylhexanoate, vinyl stearate, vinyl hexyl ether, and vinyl octadecyl ether;
- providing said rubbing contact between said first solid material and said second solid material in a manner subjecting said lubricating gaseous composition to tribological conditions, whereby said lubricating gaseous composition reduces wear and friction of at least one of said first solid material at said first surface and said second solid material at said second surface exposed to rubbing contact.
