Abstract:
According to the method of the invention, first a paste is produced from a plastics dispersion and fillers in order to form the plastics sliding layer. This paste is free from organic solvents and is applied to a sintered porous metal layer. The resultant multi-layer material is then sintered. Since organic solvents are not used, the risks to health and the risk of fire are considerably reduced. Furthermore, the composite materials produced according to the invention have exceptional resistance to cavitation. In addition to conventional fields of application relative to lubrication-free articles, such as bearings, these composite materials can therefore also be used in gear pumps and shock absorbers.

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.
