    Abstract: In some examples, an article includes a substrate and a coating on the substrate. The coating includes a stabilized microstructure including Magnéli oxide phase including an oxide of at least one of W, Mo, Nb, Ta, or Re. In some examples, a technique may include forming a coating including a refractory metal on a surface of a substrate. The technique also may include heat treating the coating at a temperature between about 500° C. and about 700° C. to form a coating including a stabilized microstructure including Magnéli oxide phase. The stabilized microstructure including Magnéli oxide phase may include an oxide of at least one of W, Mo, Nb, Ta, or Re. In some examples, the coating including the stabilized microstructure including Magnéli oxide phase exhibits a coefficient of friction that is at least 25% less than the coefficient of friction exhibited by the as-deposited coating under similar conditions.

    Abstract: A nanostructure that includes a multi-layered fullerene-like nano-structure composed of a plurality of layers each having a metal chalcogenide composition that has a molecular formula of MX2, in which M is a metallic element selected from the group consisting of titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), zirconium (Zr), niobium (Nb), molybdenum (Mo), technetium (Tc), ruthenium (Ru), rhodium (Rh), palladium (Pd), silver (Ag), cadmium (Cd), hafnium (Hf), tantalum (Ta), tungsten (W), rhenium (Re), osmium (Os), iridium (Ir), platinum (Pt), gold (Au), mercury (Hg) and combinations thereof, and X is a chalcogen element selected from the group consisting of sulfur (S), selenium (Se), tellurium (Te), oxygen (O) and combinations thereof. An outer layer of the multi-layered fullerene-like structure includes at least one sectioned portion that extends along a direction away from the curvature of the multi-layered fullerene-like nano-structure.

    Abstract: A sliding layer for a multi-layer bearing material that is free of lead. The sliding layer can include PTFE, sphalerite, and solid lubricants. The solid lubricants can include graphite and antimony oxide. In some embodiments, the sliding layer includes from 70 to 89 vol % PTFE, from 10 to 20 vol % sphalerite, and from 1 to 10 vol % solid lubricant (for example, graphite and antimony oxide).
