FIELD: working of steel products, possibly restoration of worn surfaces of cylindrical articles such as cylinders of sucker rod depth pumps.
SUBSTANCE: method comprises steps of mechanical working, iron plating of inner surface of article, carburization, chrome plating and further heat treatment with isotermal soaking at temperature of obtaining large-flake pearlite.
EFFECT: restoration of geometry parameters of inner surface of worn cylindrical articles, enhanced strength and predetermined surface roughness of articles.
