METHOD OF PRODUCTION OF THE WEAR-RESISTANT LAYER ON THE WORKING SURFACE OF THE STEEL DETAIL Russian patent published in 2007 - IPC C23C24/10 F16C33/24 

FIELD: powder metallurgy; mechanical engineering; methods of production of the wear-resistant layer on the working surface of the steel detail.

SUBSTANCE: the invention is pertaining to the methods of production of the wear-resistant layer on the working surface of the steel detail by means of the powder metallurgy and may be used for production of the wear-resistant layer on the working surface of the steel details of the friction assemblies. On the mold surface fix inserts made out of the wear-resistant material having the more higher hardness - from 87 up to 91 HRA, than the hardness of the impregnated powder of the wear-resistant material. The inserts on the mold surface are fixed by means of the gluing material, in the capacity of which use the cyanoacrylate adhesive. The mold is made out of blacklead, ceramics or the metal. The details in the mold are located with the clearance of no less than 0.3 mm between the inserts -and the working surface of the steel detail with formation of the cavity. In the cavity they place the powder of the wear-resistant material and the metal- binder. Heating is conducted with provision of impregnation of the powder of the wear-resistant material with the melted metal-binder and adhesion of the surface of the inserts with the working surface of the detail. After production of the layer the mold is removed and the detail machining is conducted. The presented method allows to increase the wear resistance of the surface of the steel detail in comparison with the prototype approximately by 20 %.

EFFECT: the invention allows to increase the wear resistance of the surface of the steel detail in comparison with the prototype approximately by twenty percent.
