An anti-friction lacquer has a resin matrix of a polymer and functional fillers containing mixed-phase oxides having a specified grinding hardness and proportion and optionally contain further functional fillers. A sliding element is also disclosed having a metallic substrate layer and a coating applied to the substrate that is made of at least in part of the anti-friction.

A non-stoichiometric nanocomposite coating and method of making and using the coating. The non-stoichiometric nanocomposite coating is disposed on a base material, such as a metal or ceramic; and the nanocomposite consists essentially of a matrix of an alloy selected from the group of Cu, Ni, Pd, Pt and Re which are catalytically active for cracking of carbon bonds in oils and greases and a grain structure selected from the group of borides, carbides and nitrides.

A lubrication method including lubricating a sliding member which contains at least one selected from the group consisting of a liquid crystal polymer and polyetheretherketone by using a lubricating oil composition which contains an ester as a lubricating base oil.

A lubrication method including lubricating a sliding member which contains at least one selected from the group consisting of a liquid crystal polymer and polyetheretherketone by using a lubricating oil composition which contains an ester as a lubricating base oil.

A link chain cleaning and lubricating device, and lubricants for use therein.

The invention relates to an imide polymer-based solid film lubricant, a method for producing same, a sliding element comprising same and the use thereof. According to the method, difunctional or cyclized difunctional compounds and optionally functional fillers are added to a non-imidized or partly imidized polyamide acid prepolymer or an imidized short-chain blocked prepolymer in a solvent or solvent mixture and then, depending on the prepolymer, a polymerization reaction or an imidization reaction and in both cases a crosslinking reaction is carried out. The solid film lubricant comprises an imide polymer as the resin matrix and optionally functional fillers, the molecules of the imide polymer comprising groups (R.sub.1) of the difunctional compounds that additionally contribute to the crosslinking.

A tribological system, comprising a main body and a sandwich lubrication, in which the sandwich lubrication includes a binder-free solid lubricant layer comprising a solid lubricant, and a lubricant layer comprising a lubricant. The binder-free solid lubricant layer and the lubricant layer are present as separate layers on the main body and wherein the mass ratio of solid lubricant to lubricant is at most 0.05:1

Described is the use of a composition in a process for extruding metals. Said composition includes at least one sodium and/or potassium phthalate and optionally at least one phthalate of an alkaline-earth metal.

The invention relates to an anti-friction lacquer having a polymer as a resin matrix and functional fillers, the functional fillers containing mixed-phase oxides and optionally further functional fillers. The invention further relates to a sliding element having a metallic substrate layer and a coating which is applied thereon and made of at least such an anti-friction lacquer and to a method for the production thereof.
