A method for manufacturing a sliding tappet of a valve train of an internal combustion engine may include the steps of: providing a main body; applying a coating at least on a contact surface of the main body configured for contacting an associated cam. The coating may include tungsten carbide and cobalt, and the coating may be applied via high velocity oxygen fuel spraying. The method may further include the step of performing a surface finishing on the coating after the coating is applied.

Method for manufacturing a sliding tappet

A cylinder liner for an internal combustion engine may include an outer circumferential surface defined by the cylinder liner composed of a gray cast iron for integrally casting onto a cast material of an engine block. A bonding component may be included for strengthening a bond of the outer circumferential surface to the cast material of the engine block. The bonding component may include at least one of a wire mesh and a wire grid that does not melt during a casting operation of the engine block. The bonding component may be arranged at least in a predefined region on the outer circumferential surface. The bonding component may be welded at least partially to the outer circumferential surface.
