FIELD: process engineering.
SUBSTANCE: proposed invention is intended for hardening surfaces of metal structure operated in abrasive wear conditions and can be used in repair and manufacture of parts that required higher hardness and wear resistance. Proposed strip comprises at least one cemented-carbide element and subtracted jointed thereto and made from material that features weldability with hardening surface material. Said substrate has at least one through bore. Mushroom-shaped cemented-carbide element has its foot penetrating into substrate through bore. Sizes of mushroom-shaped cemented-carbide element head exceed those of substrate bore. Mushroom-shaped cemented-carbide element foot is locked in substrate bore by interference fit or welding.
EFFECT: protection of hardened surface.
