Abstract
The invention relates to a cooled ring carrier that is cast into a piston for internal combustion engines. According to the invention, the zone of the ring carrier facing the cooling channel is coated, thereby preventing air from escaping from the cooling channel through the ring carrier material to the melt during alfination of the cooled ring carrier, and forming oxides.
