Abstract:
During the break-in period of track (22) assembly components, galling can occur between the components during use. The components include a pin (68) that is received within a bushing (70) and alternatively a sleeve bearing (74) between the pin (68) and the bushing (70) depending on the load. A method to prevent or reduce galling includes applying a coating (78) of zinc phosphate and a low-friction layer (76) on top of the zinc phosphate (78). The low-friction coating (76) can be made of WS 2 (Tungsten Disulphide), BN (Boron Nitride), MoS 2 (Molybdenum disulfide) or PTFE (Polytetrafluoroethylene) and deposited during a mechanical treatment.
Abstract:
Lubrication and friction reduction improves fuel efficiency and reduces energy consumption. Effective and controllable material removal results in superior surface finishing and planarization. Nanosheets are developed with specific functionalization that can be used to reduce friction and wear, improve the fluidic property, and rheological performance.. The nanosheets can be from the graphite family, transition metal dichalcogenides, transition metal trichalcogenides, semiconducting chalcogenides, metal oxides, layered hydroxides, clays, ternary transition metal carbides and nitrides, and zirconium phosphates and phosphonates, and their corresponding dopants. Tribological, rheological, and polishing applications include lubricants, viscosity modification, and chemical-mechanical planarization. The nanosheets are useful in improving efficiency and lifetime of machinery, saving energy for mechanical operations, and optimizing manufacturing processes in surface engineering.
Abstract:
The invention relates to a sliding bearing (1) comprising a metallic support layer (2), a bearing metal layer (3) and an overlay (4) produced from a dry film lubricant. Said metallic bearing metal layer (3) is arranged between the support layer (2) and the overlay (4) from the dry film lubricant. Also, the overlay (4) comprises a matrix made from polyimide in which at least one platelet-shaped solid lubricant is contained. Fibres are also contained in the polyamideimide matrix.

A friction control composition having high and positive frictional properties for sliding steel surfaces includes a water insoluble hydrocarbon that enables a reduced water content, a rheological additive, a freezing point depressant, a friction modifier, and a lubricant.
Abstract:
A coating composition for imparting a hydrophobic film on a target surface is provided that includes an oil of a silicone oil or a fluoropolymer oil or a combination thereof, a resin, and a dry lubricant. A solvent is present to form a solution of the oil and resin. A coating is imparted to an applicator that in turn can transfer the coating as a hydrophobic film. The coating composition is stable and able to impart hydrophobic film even after storage for several weeks at elevated temperature. The coating composition does so through the exclusion of synthetic waxes especially including silicone waxes. A kit is also provided that includes a wiper blade having the above coating composition applied along with instructions for the securement of the wiper blade to a vehicle to impart the hydrophobic film to a vehicle windshield contacted by the wiper blade.
Abstract:
A nanolubricant composition is described where the lubricant composition includes a flowable oil or grease with nanoparticles dispersed in the flowable oil or grease. The nanoparticles are configured to polish a surface of a structure slowly over a period of time. The nanoparticles a hardness of at least about 7 Mohs and a diameter that is less than one half the arithmetic average roughness of the surface or a length that is less than one half of the arithmetic average roughness of the surface.
