FIELD: metallurgy.
SUBSTANCE: wire comprises a metal rod and anelectrolytically applied thereto nanocomposite coating incudling a metal matrix with distributed therein nanoparticles. The matrix contains nanoparticles of fluoride or fluoride mixture of rare-earth metal and nano-sized particles of a refractory metal boride in the following ratio of matrix volumes and nanoparticles in the coating, %: metal matrix 55-96, nanoarticles of fluoride or fluoride mixture of rare-earth metal 3-20, nanoparticles refractory metal boride 1-25. Rare-earth metal fluoride was selected from the group consisting of lanthanum fluoride, yttrium fluoride, and cerium fluoride. Titanium boride or zirconium boride is used as refractory metal boride.
EFFECT: welding wire increases strength, ductility, and toughness of alloyed steel welds.
