    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: 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: 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.
