Improved Coating for Less Friction:
The piston skirt for gasoline engines with cast or steel cylinder surfaces is usually coated with GRAFAL at Mahle. GRAFAL helps to reduce friction and hence increases the scuffing resistance. A further advantage of GRAFAL-coated pistons: They enable a closer fitting clearance which leads to significantly lower engine noise in conjunction with complex piston forms.
For the application in aluminum cylinder surfaces, Mahle uses the iron particle reinforced synthetic resin coating FERROPRINT. Mahle's new FerroTec galvanic iron layer is another ongoing development available on the market. The FerroTec technology coats the entire skirt evenly, resulting in improved running properties. These coatings are necessary to enable the combination of aluminum pistons with pure aluminum engine blocks and hence represent an essential contribution to an overall reduction in engine weight.
Mahle uses a 4032 silicon forging on the vast majority of their LS-based pistons.
