FIELD: chemistry.
SUBSTANCE: invention relates to composition of thermosetting epoxide mixture for nitriding of parts from alloyed steels during chemical heat treatment. Said composition of thermosetting epoxide mixture is a compound consisting of nitrogen-containing epoxy resin (A), amine, or amide, or amino-amide curing agent (B) and filler in form of aluminium powder (B) in the ratio, pts. wt. A:B from 100:5 to 100:80 and (A + B):B from 100:80 to 100:400.
EFFECT: increased wear and high surface hardness of parts from alloyed steels.
