Landing gear comprising a zinc-nickel deposit resistant to fretting

A landing gear (1) for aircraft comprising:

• a landing gear strut (2) extending along a main axis (X-X) of the landing gear (1);
• at least one axle (3), mechanically connected to a first side (2a) of the strut (2);
• at least one wheel (4), rotatably mounted about said at least one axle;
• at least one damper (5) arranged to dampen a sliding movement of said landing gear strut (2) on a sliding layer relative to the structure of the aircraft (6);
• the landing gear (1) further comprises at least one pair of first and second parts (7, 8, 7′8,8′), said first part (7, 7′) having a steel substrate and the sliding layer (C, C′) formed on this substrate, the second part (8, 8′) being mounted in sliding contact against said sliding layer (C, C′) with a maximum rectilinear sliding amplitude (G, G′) of this second (8, 8′) part against said sliding layer (C, C′) of the first part (7, 7′), 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, wherein:
• the 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 elements other than nickel and zinc, the remainder being zinc;
• and wherein
• the 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 alloy.
