FIELD: ferrous metallurgy, possibly manufacture of processing tools for rolling tubes. ^ SUBSTANCE: method comprises steps of mechanically working, metal plating and heat treatment. Working surface of tool is metal plated by applying aluminum layer with thickness 0.2 - 0.8 mm. Heat treatment of tool is realized by heating it up to 900-1050°C and soaking at such temperature for 3 h in order to form diffusion layer with aluminum content 5 - 10%. ^ EFFECT: enhanced wear resistance of tool, improved quality of rolled tubes. |
