Abstract:
A material having improved hardness characteristics and bearing, lower friction coefficient and increased service life in clusters of sliding friction contains powder of copper, iron, phosphorus, graphite, dust of disulphide of molybdenum and steel substrate made out of low carbohydrate steel. The material has a bimetal structure with granules inserted in a matrix. The material of the invention is especially useful in the machine-building industry, particularly for the production of blocks for units of sliding friction in machines, mechanisms and equipment.
Abstract:
Method and System of lubricating at least one moving part with a medium. The medium includes a dissolved mixture of lubricant and compressed gas. The amount of lubricant and compressed gas may be controlled in forming the dissolved mixture in response to input conditions. A user and/or external factors may be used to determine the input conditions. In response to the input conditions the amount of lubricant and compressed gas is delivered to the moving part that is housed in a pressurized chamber. The properties of the dissolved mixture can be adjusted, whereby the properties may include, but are not limited to, the following: viscosity, temperature, and thermal conductivity. This adjustment to the gas may be accomplished, for example, by releasing gas from the pressurized chamber in an amount to adjust the properties. In a further approach, lubricant may be scavenged from the pressurized chamber by returning surplus lubricant to its original source or other designated location.

Abstract:
The invention relates to mechanical engineering and can be used for friction assemblies. The aim of the invention is to develop a method for forming an antifriction coating for contacting sliding surfaces, which increases the constancy, resistance and life time of said antifriction coating when subjected to normal and intensive mechanical and temperature actions and to ensure a high wearability of the surfaces. The inventive method consists in placing a mechanically pre-activated pulverized mixture of a material and a binding agent, which form the antifriction coating, between the sliding surfaces. Compositions of natural minerals containing in mass %: Mg3Si2O5 (OH)4 - 10-60, MgFe2O4 - 10-60, MoS2 - 1-20, and of associated rare-earth elements - 0,1 - 10, H2O - not more than 5, are used as the material forming the antifriction coating. The mechanical pre-activation can be carried out with a pressure pulsation in a range of 0.01 - 10 MPa at a temperature of 100-200 DEG C.
