MANUFACTURING METHOD OF PRODUCTS BASED ON TUNGSTEN-COPPER AND MOLYBDENUM-COPPER PSEUDOALLOYS Russian patent published in 2012 - IPC B22F3/26 C22C1/04 

FIELD: metallurgy.

SUBSTANCE: invention refers to powder metallurgy, and namely to production of products from pseudoalloy materials such as tungsten-copper and molybdenum-copper. Workpieces are pressed from tungsten or molybdenum charge, sintered till tungsten or molybdenum frames are obtained, and sintered frames are saturated with copper. Prior to copper saturation of frames, their surface, except the sections through which copper saturation is performed, is coated at least with one layer of material resistant to saturation temperature and not wetted with molten copper.

EFFECT: producing the parts with density of up to 99,3-100% with absence of anisotropy of properties.
