Abstract:
The present invention relates to a method for applying hexagonal boron nitride to a rough surface, wherein it is intended for the boron nitride to be provided as a temperature-resistant lubricant of the surface. According to the invention, a pin composed of hexagonal boron nitride is rubbed with pressure over the rough surface, such that abraded boron nitride adheres to the surface.
Abstract:
The invention relates to a fitting, for example a drawer slide for household appliances, comprising two rails that can move relative to one another and that are slid toward one another by way of rolling elements. In the process, the tracks (6, 8) of the rolling element (4) are lubricated at the rails (2, 3) at least in areas by way of a lubricant (7) comprising a boronitride and/or polysiloxane. This facilitates an efficient use of lubricant (7), which is also stable at high temperatures. The invention further relates to a lubricant, in particular for fittings in household appliances, that is stable at temperatures of over 600° C. and can be used in wet and humid areas.
Abstract:
In one embodiment, a substrate, for example a tool used in hot metalforming operations, is coated with an enamel nanoparticulate graded coating. The nanoparticles in the coating may be boron-nitride nanoparticles. The coating may include a first portion adjacent a surface of the substrate, and a second portion adjacent the first portion. The first portion of the coating may have a lower volume fraction of nanoparticles than the second portion. The first portion has excellent adhesion to the surface of the substrate, and the second portion reduces friction and wear. The coated tool may be formed by applying at least one layer of a coating mixture to a surface of the tool and heating the coating mixture. A metal workpiece may be formed into an article by contacting the metal workpiece against the coated surface of the tool.
Abstract:
A solid lubricant and composition useful for lubricating the flanges of locomotive wheels, railcar wheels, rail track and in applications where it is desirable to reduce friction when metal contacts metal. The solid lubricant having from about twenty-five percent to about seventy percent by volume of a polymeric carrier, about five to seventy-five percent by volume of organic and inorganic extreme pressure additives, about zero to twenty percent by volume synthetic extreme pressure anti-wear liquid oil, and about zero to one percent by volume optical brightener.
