COMPOSITE NANOSTRUCTURED POWDER FOR COATING APPLICATION |
摘要 |
FIELD: metallurgy.SUBSTANCE: invention relates to powder metallurgy, in particular to powder production for application of wear- and corrosion-resistant coatings with high adhesive and cohesive strength by method of cold gas-dynamic spattering. The composite nanostructured powder for coatings application by the method of cold gas-dynamic spattering comprises particles containing metal core out of Hadfield steel, clad layer with thickness 4-8 mcm out of aluminium powder, diffusion layer out of intermetallic compounds with thickness 0.6-1.2 mcm created at border of the core and clad layer during annealing, and reinforced surface layer created during interaction of the clad layer and oxide reinforcing agent comprising nanoparticles 10-100 nm, at that the volume share of the oxide reinforcing agent in the clad layer is 30-40%.EFFECT: coatings made from the suggested composite nanostructured powder have high adhesive and cohesive strength, uniform hardness distribution through the coating cross-section.2 ex |
