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.

There is disclosed a material wire for wear-resistant and trobologically favorable shaped bodies manufactured by the arc spraying method, which comprises a covering ( ) and a filling ( ). The covering ( ) comprises an alloy based on aluminium with at least one further alloy component, for example magnesium or manganese. The filling ( ) comprises further alloy components for the resulting alloy of the shaped body, for example silicon. The filling ( ) may apart from the silicon also comprise further components, for example aluminium and/or boron. By way of this the composition and the material properties of the resulting alloy of the shaped body may be set.
