  • Friction piece in a lubricated medium, working at contact pressures higher than 200 MPa
    Patent number: 8859078
    Abstract: Friction part in a lubricated medium working at contact pressures above 200 MPa and having a contact surface that is textured and subjected, before or after texturizing, to a case hardening treatment for a tribological function, wherein the surface is subjected to operations for producing a periodic network of micrometric cavities having predefined shapes and sizes and a period adapted to the width of the contact surface in order to promote passage to elastohydrodynamic lubrication regime.
