FIELD: manufacture of articles with normalized properties of surface layer, namely for improving strength of press tools at pressing shapes of titanium alloys.
SUBSTANCE: method comprises steps of surfacing hard alloy layer forming reinforcing structure onto base material; applying by electric spark alloying layer of hard alloy having plastic components onto surfaces layer of hard alloy in order to provide coating with reinforcing effect; then applying onto surface of formed coating additional layer having oil-phobic properties.
EFFECT: enhanced strength of part with such coating, lowered stresses of base metal.
