Abstract:
A biphasic nanoporous vitreous carbon material with a cementitious morphology characterized by presence of non-round porosity, having superior hardness and tribological properties, as useful for high wear-force applications. The biphasic nanoporous vitreous carbon material is produced by firing, under inert atmosphere, of particulate vitrified carbon in a composition containing (i) a precursor resin that is curable and pyrolyzable to form vitreous carbon and, optionally, (ii) addition of one or more of the following: solid lubricant, such as graphite, boron nitride, or molybdenum disulfide; a heat-resistant fiber reinforcement, such as copper, bronze, iron alloy, graphite, alumina, silica, or silicon carbide; or one or more substances to improve electrical conductivity, such as dendritic copper powder, copper “felt” or graphite flake, to produce a superior vitreous carbon that is useful alone or as a continuous phase in reinforced composites, in relation to conventional glassy carbon materials.
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.
Abstract:
The present invention provides a solid stick composition comprising a thermosetting resin and a grease. Optionally, the solid stick composition may comprise a lubricant, a friction modifier, a thermoplastic placticizer or a combination thereof. The solid stick compositions may be used for application between two metal surfaces in sliding and rolling-sliding contact such as steel wheel-rail systems including mass transit and freight systems. A method of reducing energy consumption, or controlling friction between a metal surface and a second metal surface by applying the solid stick composition to one or more than one of the metal surfaces, is also provided.
Abstract:
There is provided a method for surface treatment of a sliding portion, which is an economical method, has less risk of pollution in a working environment, or a fire caused by powder dust, and yet enables high lubricativeness to be achieved, and moreover, many concavities to be formed on a sliding portion simultaneously with giving the lubricativeness. An injection particle to be obtained by blending a soft-metal solid lubricant particle of which a surface has been oxidized and a layered-structure solid lubricant particle is injected onto a surface of the sliding portion of a product to be treated at an injection speed of 150 m/sec or more, thereby to diffuse and penetrate an oxide of the soft-metal solid lubricant and the layered-structure solid lubricant into the surface to form a layer, and to form many concavities on the surface of the sliding portion.
Abstract:
A solid lubricant and composition useful for lubricating the flanges of locomotive wheels, railcar wheels, rail tracks and in applications where it is desirable to reduce friction when metal contacts metal. The solid lubricant having from about 25% to about 70% by volume of a biopolymer polymeric carrier, about 5% to 75% percent by volume of organic and inorganic extreme pressure additives, about 0% to 20% by volume synthetic extreme pressure anti-wear liquid oil, and about 0% to 1% by volume optical brightener.
Abstract:
A slide member which is excellent in the initial running-in property and can provide an excellent sliding property even under a strict sliding condition and, in particular, a slide member with a solid lubrication coating film which is excellent not only in the friction property but also in the wear resistance under the fluid lubrication, boundary lubrication and dry lubrication conditions. The slide member includes a solid lubrication coating film on a flat-plate-shaped base member, characterized in that, in the surface of the slide member, there are formed a plurality of concentrical grooves extending in the peripheral direction of the slide member surface, and, between the mutually adjoining ones of the grooves, there are formed ridge portions respectively.
Abstract:
This invention relates to a threaded joint for steel pipes which comprises a pin and a box each having a contact surface including a threaded portion and an unthreaded metal contact portion and which can be prevented from galling during repeated fastening and loosening without application of a compound grease. A solid lubricant coating which comprises a lubricating powder such as molybdenum disulfide and a resin binder is formed on the contact surface of at least one of the pin and the box. The coating is formed by applying a coating fluid and drying the applied coating by first stage heating in the temperature range of from 70null C. to 150null C. and second stage heating in the range of from higher than 150null C. to 380null C. The resulting solid lubricant coating has a hardness of 70-140 on the Rockwell M scale and an adhesive strength of at least 500 N/m as determined by the SAICAS (Surface And Interfacial Cutting Analysis System) method, and it exhibits excellent galling resistance even in the environment of high-temperature oil wells. Inclusion of ultraviolet screening fine particles such as titanium oxide fine particles in the solid lubricant coating increases the rust preventing properties of the threaded joint.
Abstract:
A waterborne lubricant is provided that can form coatings on metal surfaces, inexpensively and with little environmental pollution load, wherein said coatings exhibit very good sliding properties. Also, a surface treatment method that uses the novel waterborne lubricant is provided. The waterborne lubricant contains molybdenum disulfide and waterborne resin having specified characteristics.
