FIELD: metallurgy.
SUBSTANCE: procedure consists in cleaning and de-fatting sections of surface subjected to reduction, in application of layer of slurry composition on them and in successive drying. Composition includes mixture of binding filler containing powder of alloy of composition wt %: Ti - 15.0-40.0; Mo - 5.0-30.0; Y - 0.1-1.5; B - 0.5-2.5; Si - 26.0-79.4. Also, as binding in slurry composition there is used sol of silicon acid in volume ratio with powder of alloy from 1:3 to 3:1. Drying is performed in two stages - at room temperature during 30-60 min and at temperature 75±5°C during 10-20 min.
EFFECT: raised protective qualities of coating, avoiding burning operation.
