FIELD: processes providing increased wear resistance of steel articles surfaces due to changing composition and structure of their surface layers, possibly manufacture of cutting and die tools, articles operating in condition of abrasive wear, dry friction at high contact stresses. ^ SUBSTANCE: method comprises steps of short-duration high temperature case hardening; further diffusion saturation of steel article surfaces with carbide forming elements. Case hardening is performed at temperature 950 - 1050°C for 20 - 30 min. ^ EFFECT: improved wear resistance of steel articles subjected to mechanical loads at operation. ^ 1 ex |
