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 concerns a connecting element for a tubular component, said connecting element being overlaid with a coating comprising a principal layer constituted by a nickel-phosphorus alloy. The invention also concerns a tubular component comprising one or more such connecting elements, as well as a method for producing such a connecting element.
Abstract:
A system and method of processing an alloy ingot or other alloy workpiece to reduce thermal cracking and reduce friction between the workpiece and the forging die may generally comprise positioning a multi-layer pad between the workpiece and the forging die. An article for processing an alloy ingot or other alloy workpiece to reduce thermal cracking also is disclosed. The present disclosure also is directed to an alloy workpieces processed according to the methods described herein, and to articles of manufacture including or made from alloy workpieces made according to these methods.
Abstract:
A threaded joint for steel pipes having excellent galling resistance, rust preventing properties, and airtightness without using a compound grease comprises a pin and a box each having a threaded portion and an unthreaded metal-to-metal contact portion serving as contact surfaces. The contact surfaces of at least one of the pin and the box are coated with a multi-layered structure comprising, from the bottom, a first layer formed from a first metal or alloy, a second layer formed from a second metal or alloy which is softer than the first metal or alloy, and an uppermost layer of a solid lubricating coating comprising a lubricating powder in an organic or inorganic binder.
Abstract:
Lubricants including at least one trimetasphere, lubricant additives including at least one trimetasphere, lubricant coatings including at least one trimetasphere, corrosion-resistant coatings including at least one trimetasphere and thermally-conductive materials comprising at least one trimetasphere are provided. Methods of making and using such lubricants, additives, coatings and materials are also provided.
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 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.%.
