METHOD OF CATALYTIC ELEMENT MANUFACTURING

FIELD: technological processes. ^ SUBSTANCE: invention is referred to technological processes, namely to ways of realisation of chemical processes, in particular, to area of the general and specific catalysis. The method of catalytic element manufacturing, including preparation of catalytically active coating by spraying of a powder composition on the metal carrier using high-speed cold gas-dynamic method is described. The powder composition contains in wt %: aluminium 30-50, nickel 30-45, oxide of transition metals 1-6, oxides of rare-earth metals in the sum 1-6, alpha oxide of aluminium 5-25, aluminum hydroxide - the rest. Simultaneously with spraying of the same powder composition an erosive handling of the metal carrier surface is performed. At temperature not exceeding 100C spray a powder composition on distance of 40-70 mm from the metal carrier at speed of a composition stream of 450-600 km/s with 50-200 microns coating. ^ EFFECT: increase of mechanical strength of a catalytic element, high activity of catalytically active coating. ^ 1 cl, 1 ex
