Abstract (en)

[origin: WO2007012373A1] The invention relates to a method of producing a piston (1) with a combustion chamber recess (2) for an internal combustion engine, in which at least one region of the combustion chamber recess (2) comprising at least one recess base (20) is melt-treated in order to re-melt a material in the melt-treated region, so that a buildup of the material in the melt-treated region is changed in a layer with a definable depth, and relates to such a piston (1).
