Abstract

Modifying highly loaded surfaces of cylinders of piston engines is a method of minimizing wear and friction. There already exist coatings like ALUSIL which are used in the cylinders of some BMW and Porsche engines. The advantages of these coatings are very hard silicon particles that protrude from the aluminium matrix in which the silicon is embedded. Below the silicon particles is volume to store oil, improving the tribological performance. Another new method of modifying a surface for this purpose is a special cutting process that can produce structures with a scale from few micrometers to some millimetres.
