A cylindrical component has a groove bottom (4) that extends approximately parallel to the course of the unworked surface of the component, and has a side wall (6, 7) inclined at an angle (alpha) of less than 90° to the groove bottom (4). To increase the adhesion between a coating to be applied to the surface of the component an upper region of the side wall (6, 7) is adjoined by an oblique surface (8, 9) at an angle (Psi) of greater than 90° to the side wall.
