The coating system (20) includes at least one hard friction reducing coating deposited as an outermost layer (9) which exhibits droplets (10) at its surface. The outermost layer (9) includes molybdenum copper nitride and/or molybdenum nitride and copper nitride, and at least some of the droplets (10) consist mainly of copper. Preferably most of the largest droplets (10) consist mainly of copper.
摘要:
A system and method for forming at least one of graphene and graphene oxide on a substrate and an opposed wear member. The system includes graphene and graphene oxide formed by an exfoliation process or solution processing method to dispose graphene and/or graphene oxide onto a substrate. The system further includes an opposing wear member disposed on another substrate and a gas atmosphere of an inert gas like N2, ambient, a humid atmosphere and a water solution.

Nickel-containing carbon nanofiber (NiCNF) materials and lubricants comprising the nanofiber materials are described herein. The NiCNF materials comprise a plurality of elongate nickel-containing carbon nanofibers. Each NiCNF comprises a carbon nanofiber shaft that is capped at one end by a nickel nanoparticle encapsulated in multiple layers of graphitic carbon. The nanofibers typically have a generally circular cross-section (i.e., in the direction perpendicular to the length-axis of the fibers). The NiCNF materials as useful, e.g., in lubricant compositions, which also are described herein.

The invention relates to a lead-free sliding bearing material having a Cu-based or CuSn-based sintered matrix and a solid lubricant. The solid lubricant contains hexagonal boron nitride in a fine-grained distribution with a mean particle size of 10 μm or less, wherein agglomerates of the particles of hexagonal boron nitride are not greater than 200 μm. The invention also relates to a sintering powder for producing the sliding bearing material, a sliding bearing composite material having a steel protective layer and a bearing layer composed of such a sintered-on sliding bearing material. The invention also relates to a sliding element composed of a sliding bearing composite material of the type mentioned above.
