ABSTRACT:
In a piston for internal combustion engines, a cover layer comprising a material having a relatively low thermal conductivity has been applied to the piston head by plasma or flame spraying. To increase the life of the cover layer until it separates from the body of the piston, the surface of the cover layer has a peak-to-valley height of 5 to 30 .mu.m.
