APPLICATION OF NANOPOWDERS OF METALS IN DIFFUSION WELDING OF DISSIMILAR MATERIALS
OJSC «Ramenskoe Instrument Engineering Design Bureau», Ramenskoe, Russia
Comparative analysis of compact materials, deposited and galvanic layers, and powders with different particle size used as such layers is presented. The processes of sintering of nanopowders and their adhesion through sintering to the surfaces of parts welded are studied. It is shown that the use of double mixtures of nanopowders allows intensifying the process of diffusion formation of the welded joint and provides the welds with preset mechanical and physical properties.
