Zinc alloy wire rope will wear different degrees after using for a long time. According to the position of wear, it can be divided into external surface wear and internal surface wear. The wear caused by the friction between the common Zinc alloy wire rope and the pulley groove and other objects is called external surface wear, and the internal surface wear is the wear caused by the fretting friction between the wires of the Zinc alloy wire rope during use.

  If the internal surface wear of the Zinc alloy wire rope during use has become serious, it will cause the Zinc alloy wire rope to lose rigidity, shorten its service life, and break. Therefore, the internal fretting of the Zinc alloy wire rope will cause The damage is directly related to the fatigue fracture of the wire rope. The combined effect of fretting wear and alternating stress will cause cracks and breakage of the Zinc alloy wire rope, which will shorten the life of the Zinc alloy wire rope.
  In addition to fretting wear that can shorten the life of Zinc alloy wire rope, there are some other reasons. For example, the external surface wear is because the material surface has a certain roughness and blog, so when the surfaces contact each other, the material deformation, adhesion and relative movement of the material displacement are external surface wear. These are unavoidable wear and tear. A pure manganese phosphating film can be added between the strands of the Zinc alloy wire rope to reduce the degree of wear and tear of the Zinc alloy wire rope.
