    Abstract: In a tubular threaded joint composed of a pin 1 and a box 2 each having a contact surface comprising a threaded portion and an unthreaded metal contact portion including a seal portion and a shoulder portion, a solid lubricating coating 10 having a relatively high Knoop hardness is formed on a portion including the shoulder portion of the contact surface (such as the unthreaded metal contact portion including the shoulder portion and the seal portion) of at least one of the pin and the box, and a solid lubricating coating 11 having a relatively low Knoop hardness is formed at least on the remaining portion of the contact surface (such as the threaded portion). The tubular threaded joint has excellent galling resistance, gas tightness, and rust preventing properties, and since it has a large ΔΤ, it does not readily undergo yielding of shoulder portions even when it is made up with a high torque, thereby making it possible to perform makeup in a stable manner.

    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.
