Beschreibung
Zusammenfassung:	FIELD: mechanical engineering; other industries; production of materials with antifriction coatings for the sliding friction pairs. ^ SUBSTANCE: the invention is pertaining to the materials for the pairs of sliding friction and may be used in mechanical engineering and other branches of industry. The composite antifriction coating on the components made out of aluminum alloys contains the external antifriction layer and the arranged between it and the base made out of the aluminum alloy the layer of the ceramic-oxide of 50...300 microns thick. The external antifriction layer is made out of copper or the copper based alloy, and its thickness compounds 2...10 microns. The method of manufacture of the given coating provides for formation of the ceramic-oxide layer with the open porosity by the anode-cathode microarc oxidation and the subsequent antifriction layer costing. Before the antifriction layer coating from the ceramic-oxide surface remove the layer with porosity exceeding 10 %. Then the component is treated with the lubricant on the basis of technical glycerin. The antifriction layer is applied using the mechanically-frictional method. The rubbing plate made out of copper or on the copper basis press to the surface of the ceramic-oxide with the monotonically increasing contact pressure. The rubbing plate is heat-insulated from the pressing component of the device for rubbing and has the form of the contacting it surface. The technical result of the invention is expansion of the capabilities to create the composite antifriction coatings on the details made out of aluminum alloys, which shapes limit the possibility of their heating because of buckling. ^ EFFECT: the invention ensures expansion of the capabilities to create the composite antifriction coatings on the surfaces of the details made out of aluminum alloys, which shapes limit the possibility of their heating because of buckling. ^ 3 cl, 1 dwg
