This invention refers to metallurgy, in particular to surface alloying of steel castings. Technical result consists in increases of wear resistance and durability by increase of chromium concentrate in the cromium saturated layers. The method according to the invention comprises the steps of applying paste contatining chromium powder, aluminium oxide, ammonium chloride and binder, diffusive saturation during crustallization and cooling in the paste. For simpifying process ingot mould applied with paste wherein cryolit is additionally introduced and is used as a binder liquid glass. 1 ind. cl. 3 Tables
