FIELD: mechanical engineering; measurement technology. SUBSTANCE: method involves exposing work piece material to superficial plastic deformation due to shot-blasting treatment being applied until residual imprint on the work piece surface is produced. The residual imprint diameter on the work piece surface is measured and static shot material hardness to static work piece material hardness ratio is determined. The value is used for determining ratio of dynamic shot material hardness to dynamic work piece material hardness that is used for determining thickness of hardened superficial layer reinforced with cold working. EFFECT: controllable superficial layer thickness when selecting appropriate hardening method based on shot shot-blasting treatment. 2 tbl
