Abstract:
The present invention provides a new composite material comprising a porous matrix made of metal, metal alloy or semiconducting material and hollow fullerene-like nanoparticles of a metal chalcogenide compound or mixture of such compounds. The composite material is characterized by having a porosity between about 10% and about 40%. The amount of the hallow nanoparticles in the composite material is 1-20 wt. %.
Abstract:
Dry film lubricant coatings are provided by using a silicone resin binder, either as an aqueous emulsion or in a solvent-based system, to fix an alkaline earth metal fluoride to a substrate. The compositions used to apply the coatings may also include relatively minor amounts of xylene, ammonium benzoate, a wetting agent, and/or a porosity-inducing agent-although none of those additives remains in the cured coating. Multi-layer dry film lubricant coatings are also disclosed, with the multi-layer coating having a basecoat layer as described above, and a topcoat layer made of a layer-lattice solid such as graphite or molybdenum disulfide, and a silicone resin, aluminum phosphate or an alkali metal silicate binder.
Abstract:
Disclosed are grease compositions containing a liquid fluorinated polymer and a thickening agent containing hexagonal lattice boron nitride powder having a bimodal particle size distribution as well as grease compositions containing a liquid fluorinated polymer and a thickening agent containing hexagonal lattice boron nitride powder and a solid fluorinated polymer.
Abstract:
A solid lubricant composition comprises (I) 30 to 70 parts by weight of graphite, (II) 70 to 30 parts by weight of a mixture of at least two components selected from alkali molybdate, alkali or alkaline earth sulphate and alkali phosphate, the ratio of the two individual ingredients being in the range of from 0.05/1 to 20/1. Compositions give improved load-bearing capacity and allows settling of friction coefficient.
Abstract:
The invention aims at providing a hard coating film excellent in lubrication characteristics; a process for the formation thereof; and tools for the plastic working of metal, and provides a hard coating film covering the surface of a substrate to come into contact with other member, wherein carbon atoms having carbon-carbon bonds are present in an amount of 10at% or above. It is preferable that the hard coating film contain titanium carbide, while it is preferable to form a titanium nitride coating layer between the surface of the substrate and the hard coating film. The invention also provides a process for the formation of a hard coating film on the surface of a substrate by arc ion plating which comprises introducing a hydrocarbon gas during the arc ion plating with a metal target and which makes it possible to form on the surface of a substrate a coating film where carbon atoms having carbon-carbon bonds are present in an amount of 10at% or above. It is preferable that prior to the introduction of a hydrocarbon gas, nitrogen gas be introduced to form a metal nitride layer on the surface of the substrate. Further, the invention provides tools for the plastic working of metal whose working surfaces are covered with the hard coating film.
