A multiphase composite lubricant for a railway lubricant stick that can be used in both low and high temperature applications. The composition of the multiphase composite lubricant includes an amount of a lubricant, an amount of a thermoplastic lattice components that forms a lattice structure, and a polymer extender.

A solid lubricating coating film capable of imparting favorable lubricity and corrosion resistance to a connection for oil country tubular goods. Two or more solid lubricants are dispersed in a binder resin. Graphite is contained in an amount of 50% or more and 90% or less of a total weight of the solid lubricants, and the graphite has a scaly shape and an average particle diameter of 10.0 m or less. A solid lubricant made of one or more materials selected from BN, mica, talc, MCA, MoS.sub.2, PTFE, PFA, and FEP is further contained as other solid lubricants of the two or more types of solid lubricants. The binder resin contains a PEEK resin having an average particle diameter of 20 m or less as a main component, and the PEEK resin is contained in an amount of 70% or more of a total weight of the binder resin.

A coated article includes a substrate, and a coating disposed on a surface of the substrate. The coating comprises a transition metal dichalcogenide (TMD). A method of forming a coating includes dispersing a transition metal dichalcogenide (TMD) and optionally tungsten carbide in a solvent to form a mixture, spraying the mixture on a surface of a substrate, evaporating the solvent, and forming a coating on the substrate comprising the TMD.

A cold spray lubricant for forming a coating includes an alloy feedstock consisting of a metal powder such as copper or nickel, and a solid lubricant, such as tungsten disulfide (WS.sub.2) powder or molybdenum disulfide (MoS.sub.2).

The present invention is concerned with a method of generating a lubrication interface. The method has the steps of a) providing a target substrate and a growth substrate adjacent the target substrate with a confinement space defined therebetween, b) allowing a predetermined amount of water onto a surface of the target substrate in the confinement space thus forming a water layer, c) adding a predetermined amount of a sample of a molybdenum disulfides (MoS.sub.2) layer on the water layer thus allowing the water in the water layer to bind with the surface of the molybdenum disulfides (MoS.sub.2) layer, d) cooling down the target substrate to cryogenic temperature so as to freeze the water layer thus forming a molybdenum disulfides (MoS.sub.2) ice layer on the target substrate, and e) detaching the growth substrate from the molybdenum disulfides (MoS.sub.2) ice layer thus leaving the molybdenum disulfides (MoS.sub.2) ice layer.

A sliding member according to the present disclosure contains, in a sliding layer, a synthetic resin, a solid lubricant, and an additive. The synthetic resin is a polyimide, a polyamide imide, a polybenzimidazole, a polyphenyl sulfone, a polyether sulfone, a polyether ether ketone, or a combination thereof. The solid lubricant is a polytetrafluoroethylene, a tetrafluoroethylene-perfluoroalkoxyethylene copolymer, molybdenum disulfide, a tetrafluoroethylene-hexafluoropropylene copolymer, or a combination thereof. The contained amount of the solid lubricant in the sliding layer is 5.0-40.0 vol. %. The additive is bentonite, smectite clay mineral, silica, a polyamide, or a combination thereof. The contained amount of the additive in the sliding layer is 0.1-9.0 vol. %.

A method of making an antifriction coating composition, comprising the steps of (A) combining (i) a solid lubricant, (ii) a solvent, (iii) a binder, and (iv) optionally, an additive; and (B) grinding the (i) solid lubricant in the solvent (ii) with a basket mill for sufficient time to form a dispersion of the ground (i) solid lubricant in the (ii) solvent, and wherein the binder (iii) and the optional additive (iv) are each independently combined with the solid lubricant (i) and solvent (ii) before, during, after, or a combination of two or more of before, during, and after, (B).

Anti-friction composite material having: (A) polyimide substrate and (B) a coating layer containing a binder resin and a solid lubricant.
