A landing gear () for aircraft comprising a first pair of first and second parts (′), said first part (′) having a steel substrate and a sliding layer (C, C′) formed on this substrate, the second part (′) being in sliding contact against said sliding layer (C, C′) with a maximum rectilinear sliding amplitude (G, G′) of less than 0.5 mm, the sliding layer (C, C′) being adapted to support a surface pressure in excess of 50 MPa. 11. A landing gear () for aircraft comprising:{'b': 2', '1, 'a landing gear strut () extending along a main axis (X-X) of the landing gear ();'}{'b': 3', '2', '2, 'i': 'a', 'at least one axle (), mechanically connected to a first side () of the strut ();'}{'b': '4', 'at least one wheel (), rotatably mounted about said at least one axle;'}{'b': 5', '2', '6, 'at least one damper () arranged to dampen a sliding movement of said landing gear strut () relative to the structure of the aircraft ();'}{'b': 1', '7', '8', '7', '8', '7', '7', '8', '8', '8', '8', '7', '7, 'the landing gear () further comprises at least one pair of first and second parts (, , ′, ′), said first part (, ′) having a steel substrate and a sliding layer (C, C′) formed on this substrate, the second part (, ′) being mounted in sliding contact against said sliding layer (C, C′) with a maximum rectilinear sliding amplitude (G, G′) of this second (, ′) part against said sliding layer (C, C′) of the first part (, ′), strictly less than 0.5 mm, the sliding layer (C, C′) being adapted to support, at least during the sliding, a surface pressure in excess of 50 MPa, whereinthe sliding layer (C, C′) is made of a zinc and nickel alloy comprising, in terms of percentage by weight of the alloy, between 12% and 18% nickel, at most 0.5% of other elements such as nickel and zinc, the remainder being zinc; and whereinthe first part also has a protective layer (P, P′) against corrosion extending from the sliding layer (C, C′), this protective layer (P, P′) being formed of said zinc and nickel ...
