This ball joint member (1), of the type including an inner ring (10), with a general axisymmetrical shape around a first axis (X10), comprises an external contact surface (14) having a truncated spherical shape, the inner ring (10) including a coating which bears the external contact surface (14) and an outer ring (12), of a general axisymmetrical shape around a second axis (X12), comprising an internal contact surface (16) mating said external contact surface (14), cooperating with said external contact surface (14), the outer ring (12) including a coating which bears the internal contact surface (14). At least one of the inner and outer rings (10, 12) comprises lubricant reservoirs (20, 21, 160; 22) made on the coating of one of the external and internal (14, 16) contact surfaces and the coating of the contact surface (14, 16) of one of the rings (10, 12) is textured with microcavities (18) forming the lubricant reservoirs. |
