In a method for producing a piston for an internal combustion engine, at least the region of the upper annular groove is at least partially recessed, an adhesion promoter layer containing aluminum is then applied, a wear-resistant layer is thermally sprayed onto said adhesion promoter layer and at least the upper annular groove is at least partially formed in said layers. The invention also relates to a piston for an internal combustion engine that comprises a base material, an adhesion promoter layer that contains aluminum and is applied to at least some regions of said material and a wear-resistant layer that is thermally sprayed onto said adhesion promoter layer. At least the upper annular groove is at lest partially formed in said layers.

Method for producing a piston for an internal combustion engine and piston for an internal combustion engine

The invention relates to a method for producing an internal combustion engine piston which is provided with at least one cooling channel () and at least one reinforced piston ring groove () consisting in producing a piston blank (), in forming a groove () provided with a cooling channel () and an external ring () in said piston blank (), in filling the cooling channel () with are movable material (), in filling the external ring with a reinforcing material () in removing the removable material () and in finish-machining the piston. A piston made of aluminum alloy and produced according to the inventive method is also disclosed.

Method for producing a piston for an internal combustion engine and the thus produced piston

In a method of producing a piston ( ) for an internal combustion engine including at least one strengthened piston ring groove at least one relatively narrow groove ( ) is configured in the region of the upper and/or lower flank of the provided piston ring groove ( ) and the groove ( ) is filled with a hard-wearing material ( ) and the piston ring groove ( ) is worked out such that the upper and/or lower flank is formed at least in part by the hard-wearing material ( ).
