Abstract:
A piston for an internal combustion engine may include a shaft. A dual-layer coating with an inner layer and an outer layer may be applied to the shaft. The inner layer may include organic binders and solid lubricants. The inner layer may also include hard material particles of at least one of tungsten disulphide (WS2), tungsten carbide (WC), silicon carbide (SiC), and aluminum oxide (Al2O3). The outer layer may include inorganic binders, may be air-hardening, and may have a lower wear resistance than the inner layer.
