An anti-galling method for treating materials, which provides for subjecting at least one of the at least two components mutually coupled with at least one degree of freedom, made of metallic material, to a first preliminary step of thermal treatments to increase surface hardness and to a second preliminary step of surface grinding. The method further includes the steps of: washing at least one portion of the surface of the at least one component subjected previously to the preliminary steps; shot peening the at least one portion of the surface of the at least one component previously subjected to washing; and applying a layer of molybdenum disulfide to the at least one portion of the at least one component previously subjected to shot peening.

An antifriction coating formulation composition comprising (a) a soluble resin, (b) an insoluble polymer, (c) optionally a solid lubricant, and (d) a solvent.

Additive packages including multifunctional additive molecules are disclosed, including, for example, organic medium intercalated with lubricant nanoparticles. The additive package may be greaseless or may be added to materials such as base oils or greases, greaseless materials, or anti-corrosives, for example. The additive package added to materials may form a coating or lubricant that may be added to a surface of an object.

Lubricating compositions are provided. The lubricating compositions can include a lubricating agent, a flexibilizer, a dispersing agent, and a charge imparting agent. The lubricating compositions can optionally include a carrier.

A friction control composition having high and positive factional 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.

A resin composition for use in a sliding member, which has higher seizing resistance while maintaining abrasion resistance. The sliding resin composition includes: a resin binder; a solid lubricant; and a protecting and reinforcing agent that is harder and brittler than the resin binder. As the protecting and reinforcing agent, aggregates of particles harder than the resin binder are used. The amount of the protecting and reinforcing agent contained is 1 vol. % or more but 20 vol. % or less of the entire sliding resin composition. The particles harder than the resin binder have an average particle diameter of 10 nm or more but 100 nm or less that is smaller than that of the solid lubricant.

A resin composition used for a sliding member to improve seizing resistance. The sliding resin composition includes: a resin binder; a solid lubricant; and aggregates of particles. A coupling force between the particles in the aggregates is smaller than a threshold stress of the resin binder so that the aggregates exposed at a surface of the resin binder are partially detached with a force smaller than the threshold stress of the resin binder. The aggregates of the particles harder than the resin binder are used as a protecting and reinforcing agent, and the amount of the particles contained in the sliding resin composition is 1 vol. % or more but 20 vol. % or less of the entire sliding resin composition. The particles harder than the resin binder have an average particle diameter of between 10 nm and 100 nm that is smaller than that of the solid lubricant.

A coating composition for a lubricating coating film includes: (A) a phenolic resin (B) an epoxy resin having an epoxy equivalent weight of 600 to 4000; and (C) at least one type of solid lubricant. The epoxy equivalent weight is generally defined by the number average molecular weight per the number of epoxy groups in a single molecule. The coating composition has a weight ratio of component (A) to the total weight of component (A) and component (B) of at least 50 weight %. A lubricating coating film, formed from the coating composition, has a high level of flexibility on surfaces of various base materials.

A lubrication mechanism of a strain wave gearing is disposed in an interior space of an externally toothed gear and comprises a powder-accommodating bag that stores solid lubricant powder. A diaphragm of the externally toothed gear is repeatedly deflected during the driving of the strain wave gearing. Vibration or deflection is repeatedly imparted to the powder-accommodating bag and the solid lubricant powder is discharged from a powder discharge hole formed in the powder-accommodating bag into the interior space. A site to be lubricated is lubricated with the solid lubricant powder discharged into the interior space. Harmful effects due to a large amount of the solid lubricant powder being supplied to the site to be lubricated at one time can be resolved, and a necessary amount of the solid lubricant powder can be continuously supplied to the site to be lubricated.

A composition includes molybdenum disulfide, epoxy binder, and 0.01 to 3 wt % lead. The composition is useful, for example, as dry film lubricant.
