CERAMIC FLUX Russian patent published in 2013 - IPC B23K35/362 

FIELD: process engineering.

SUBSTANCE: invention can be used in mechanized building-up and welding of low-carbon low-alloy steels using ceramic fluxes. Flux contains components in the following ratio in wt %: calcium carbonate 20-25, fluor-spar 50-60, alumina 10-20, feldspar 3-6, magnesite 1-3, ferromanganese up to 1, complex foundry alloy 3-15. The latter consists of nickel 50-70 wt % and nano-disperse refractory components embedded therein in amount of 30-50 wt %. Said refractory components represent elements of transition metals of IV, V and VI groups or their heat resistant chemical compounds with carbon, nitrogen or boron.

EFFECT: higher ductility and impact toughness.
