Abstract (en)
[origin: WO2015110379A1] The invention relates to a piston (10) for a piston machine. The piston (10) consists of a steel or a lightweight metal alloy (15) in some regions and comprises a layer stack (20) arranged on a piston base (11) of the piston (10). The layer stack (20) comprises at least one first layer (21) which directly or indirectly adjoins a surface of the piston base (11) and which comprises a heat-damping material and a second layer (22) which directly or indirectly adjoins the first layer (21) and which contains a heat-conducting material. According to the invention, the diameter (dS) of the layer stack (20) is smaller than the diameter (dK) of the piston base (11). The invention further relates to a piston machine comprising a piston according to the invention.
