The invention relates to a friction piece in a lubricated medium, working at contact pressures higher than 200 MPa. The surface is subjected to operations for creating a periodical network of micrometric cavities of determined shapes and sizes, the period being adapted to the width of the contact surface in order to facilitate the transition to the elastohydrodynamic lubrication regime.
La présente demande concerne une pièce de frottement en milieu lubrifié, pouvant travailler à des pressions de contact supérieures à 200 MPa, où ladite surface est soumise à des opérations aptes à réaliser un réseau périodique de cavités micrométriques de formes et dimensions déterminées et dont la période est adaptée à la largeur de surface en contact afin de favoriser le passage en régime de lubrification élastohydrodynamique.
