Abstract
The present invention relates to a mechanical system (1), comprising a bearing (4) and a shaft (10) coupled to the bearing (4), especially for an internal combustion engine, being subjected to average contact pressures of less than 200 MPa. The shaft (10) has at least one area (12) provided with an anti-seizing surface coating (20), having a surface hardness at least twice that of the bearing (4), and a microtexturation (30) comprised of a set of individual microcavities (31), distributed in said area (12). The invention also relates to a method for manufacturing such a mechanical system (1).
