FIELD: metallurgy.
SUBSTANCE: here is claimed alloy on base of quazi-crystal system Al-Cu-Fe for application of wear resistant nano structured coating. Alloy contains copper in form of independent phase and tungsten carbide at the following ratio of components, wt %: copper 2-5, tungsten carbide 20-40, quazi-crystal of system Al-Cu-Fe - the rest. Also, quazi-crystal of system Al-Cu-Fe has the following composition, wt %: aluminium 65, copper 21.5-23.5, iron 11-13.5. Technical result of the invention is increased wear resistance due to increased micro-hardness of material together with increased adhesion and cohesion strength of applied coating.
EFFECT: alloy possesses high micro hardness and can be used for application of wear resistant coating.
