In addition to fretting wear, there are other reasons for the shortened life of galvanized steel wire rope. For example, the external surface wear is because the surface of the material has a certain roughness and corrugation. Therefore, when the surfaces contact each other and slide against each other, the material is displaced and the surface coating is peeled off due to the deformation of the material, the degree of adhesion, and the tearing of the adhesive point during relative movement. The resulting losses are so-called external surface wear. It is precisely because of the sliding phenomenon between the wires between the inner strands of the galvanized steel rope that the galvanized steel wire rope has the problem of wear, because when the galvanized steel wire rope is put into use, the fretting between the wire rope strands is inevitable. Adding pure manganese phosphating film between the galvanized steel wire rope strands is an effective measure to solve the internal surface wear of the wire rope.
