Generally, nylon coated stainless steel wire rope products will produce certain wear, and the wear is also divided into external surface wear and internal surface wear. Then the wear caused by the friction between the surface of the galvanized steel wire rope and the pulley groove and other objects is what we call external surface wear; and the internal surface wear we call is usually the galvanized steel wire rope during use loss due to fretting friction.

If the internal fretting surface wear of nylon coated stainless steel wire rope products during use has formed extremely serious wear and tear on the surface between the wire strands, it will lead to failure of the galvanized steel wire rope, resulting in a shortened life and a short life. As a result, the steel wire will be fatigued and even fractured, so it also relatively reflects the correlation between the wear damage caused by the fretting of the inner surface of the galvanized steel wire rope and the fatigue fracture caused by the fretting. The joint action between fretting wear and alternating stress will accelerate the generation and fracture of fatigue cracks in galvanized steel wire ropes, because such wear and tear shortens the service life of galvanized steel wire ropes greatly, so fretting wear is the failure of galvanized steel wire ropes. The main reason for the shortening of lifespan.

In addition to fretting wear, there are other reasons for the shortened life of nylon coated stainless steel wire rope products. 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.
