Some variations provide a low-adhesion coating comprising a continuous matrix containing a first component, a plurality of inclusions containing a second component, and a solid-state lubricant distributed within the coating, wherein one of the first component or the second component is a low-surface-energy polymer, and the other of the first component or the second component is a hygroscopic material. The solid-state lubricant may be selected from graphite, graphene, molybdenum disulfide, tungsten disulfide, hexagonal boron nitride, or poly(tetrafluoroethylene) or other fluoropolymers. The solid-state lubricant particles may be coated with a metal selected from cadmium, lead, tin, zinc, copper, nickel, or alloys containing one or more of these metals. The solid-state lubricant is typically characterized by an average particle size from about 0.1 μm to about 500 μm. The solid-state lubricant is preferably distributed throughout the coating.

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.

Surface micro-texturing has been proven an effective way to reduce friction and wear for tribological applications. There is provided a low cost hot sintering method to apply micro-texturing on an advanced bearing polymer material. First, one face of the mold was micro-textured using a micro-casting method. Second, the cured Aromatic Thermosetting coPolyester (ATSP) powder was filled in the mold. Next, the filled mold was placed in a hot press for a hot sintering process. Finally, the textured bulk ATSP was cooled. The micro-textured ATSP bulk material was machined and compared with plain untextured material. The micro-textured material could effectively reduce friction at speeds lower than 2.46 m/s: 14% reduction in average.
