A piston for an internal combustion engine may include a piston head and a piston skirt. The piston skirt may have piston bosses provided with boss bores. The piston bosses may be connected to each other at running surfaces. The running surfaces may be provided at least partially with a coating which is sprayed using a cold gas method. The material of the coating may be selected from the group comprising at least one of nickel, iron, copper, nickel-based alloys, iron-based alloys, copper-nickel-tin-based alloys and copper-tin-silver-based alloys. |
