Abstract (en)

[origin: WO2010142439A1] The invention relates to a method for producing a piston of an internal combustion engine, wherein the piston has a combustion bowl comprising a combustion bowl rim, and the combustion bowl rim is hardened by being remelted in a first step by means of an inductive energy supply and in a further step by means of a laser beam. According to the invention, the laser beam is deflected during a rotary, progressive motion relative to the piston.
