Abstract
A procedure for hardening at least one surface (S, L) of a wall (W) of a component (T), in which the surface to be hardened (S, L) is inductively heated with at least one inductor ( ), in which liquid is filled into a gap (P) between the surface to be hardened (S, L) and the inductor ( ) while heating the surface to be hardened (S, L), in which the side (AS) of the wall (W) opposite the side (IS) of the wall (W) provided with the surfaces to be hardened (S, L) is sprayed with liquid while heating the surface to be hardened (S, L), and in which at least one liquid jet (KI) is aimed at a zone (RZ) of the wall (W) that is adjacent to the surface to be hardened (S, L), and to be precluded from heating by the inductor ( ). The procedure according to the invention makes it possible to tailor the hardening of at least one surface to the respective requirements, even on the walls of complexly shaped components with a small wall thickness.
