Abstract
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.
 
 
Keywords: diffusion welding, powder intermediate layer, nanopowders of metals, intensification of process of joining, welding temperature, time of welding, pressure, structure of metal in zone of joining
