Tribology system and internal combustion engine having the same

摘要

The present invention comprises a first body (102; 105) and a second body (101) each forming a component of an internal combustion engine (100), in particular a piston (102), a piston ring (105) or a cylinder (101, 107). 107), the surfaces (112, 108, 113) of the first body (102; 105) and the second body (101; 107) have at least some areas during operation Have a first material area and a second material area (11, 12) forming contact with each other to form a tribological contact, the first material area and / or the second material area (11, 12) being oxidized It is formed as a layer based on chromium or aluminum chromium oxide. The invention also relates to an internal combustion engine (100) comprising such a system (1; 2).
