DISPERSE COMPOSITE MATERIAL

摘要

FIELD: chemistry.SUBSTANCE: invention relates to welding, in particular to manufacturing powders, used for PTA surfacing of antifriction reinforcing coatings in manufacturing wear-resistant components. A disperse composite material for surfacing antifriction coatings based on aluminium bronze contains, wt %: 0.5-2.5 aluminium oxide nanopowder with the particle size 20-140 nm, aluminium bronze powder - the remaining part.EFFECT: application of the composite material makes it possible to increase the hardness and wear-resistance of coatings or welded connections.7 dwg, 2 tbl
