摘要:
Fluid compositions comprised of a monomer constituent dissolved in a carrier fluid, where the monomer constituent is capable of forming a polymer film directly on rubbing surfaces but is not polymerized in solution, have been found to be effective for reducing ceramic wear.
摘要:
Compositions for reducing wear and friction of rubbing surfaces including mixtures of a cyclic amide and a monoester formed by reacting a dicarboxylic acid and a polyol in substantially equimolar amounts where the dicarboxylic acid is a dimer of an unsaturated fatty acid. The invention also relates to methods of use of such compositions.

摘要:
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.
摘要:
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.
摘要:
A method for reducing wear of ceramic cutting components during machining operations in which surface material is removed from a workpiece with reduced friction and with improved surface finish imparted to the reshaped workpiece. The method uses of cutting fluid compositions containing monomers capable of forming polymers in situ when subjected to tribological conditions (such as high temperature, pressure, and friction) existing at the contact area developed between the ceramic tool and surface of the workpiece during machining.
摘要:
Method of testing the lubricating properties of the lubricating means consisting in that in a test master rubbing pair, operating at a definite temperature and with definite unit pressures, or at a definite temperature and with a definite rubbing speed, at the presence of the lubricating means being tested, either the slip rates are gradually decreased in a linear way, or the unit pressures are gradually increased also in a linear way and, at the same time, parameters characterizing these properties are recorded. The rubbing speed is gradually decreased down to a minimum limit value, or the unit pressures are gradually increased to a definite maximum limit value corresponding to a condition, when the electric resistance and the friction force attain the values characteristic for the dry friction.In the device according to the invention the rotary test piece (1) is mounted on a shaft of an electric motor (2). Two counter-specimens are mounted in holders (5) accommodated in the insulating guideways (6) mounted in the device body (7), the said device consisting of an inner chamber (8) containing the lubricating means to be tested (9) and of an outer chamber (11) containing the thermostatic liquid (12). The motor housing (2) is connected to the body (7) by means of a ball bearing (13) and a spring element (14).
