A piston for an internal combustion engine may include a piston head and a piston skirt. The piston skirt may include piston bosses disposed opposite one another having a boss bore and at least two shank walls disposed opposite one another having a running surface. A cover plate including a recess for receiving a connecting rod may be secured in a lower region of the piston skirt. The cover plate may have at least two longitudinal sides disposed opposite one another and at least two free ends disposed opposite one another. At least two grooves may be arranged in the lower region of the piston skirt on the at least two shank walls. The at least two free ends of the cover plate may be accommodated resiliently prestressed in the at least two grooves.

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.
