Abstract
Method of reducing wear between rubbing surfaces by contacting a surface of a solid material with a cyclic amide before and/or while it is being rubbed against another surface.
Claims13
A method reducing wear between rubbing surfaces, comprising the steps of:
- providing a first solid material having first surface in rubbing contact with a second surface of a second solid material;
- contacting said first surface with a cyclic amide in an amount effective to reduce wear of said rubbing surfaces, wherein said cyclic amide has the formula:
- ##STR10## where x is a positive integer ranging from 5 to 11, wherein said first solid material and second solid material are each independently selected from the group consisting of metals, ceramics, fiber-reinforced polymeric composites, plastics, and wood.
A method for reducing wear in rubbing parts 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;
- contacting at least said first surface of said first solid material with a lubricating composition comprising a carrier medium and cyclic amide, wherein said carrier medium is selected from the group consisting of a liquid, a gas, and a semi-solid, and
- wherein said cyclic amide has the formula:
- ##STR11## where x is a positive integer ranging from 5 to 11;
- providing said rubbing contact between said first solid material and said second solid material, whereby said lubricating composition reduces wear and friction of at least one of said first solid material at said first surface or said second solid material at said second surface exposed to said rubbing contact, wherein said first solid material and second solid material are each independently selected from the group consisting of metals, ceramics, fiber-reinforced polymeric composites, plastics, and wood.
