Manganese phosphating belongs to wear-resistant and corrosion-resistant phosphating. After manganese phosphating treatment, the automobile gear box steel gear can be guaranteed not to be damaged for more than ten years. The phosphating coated steel wire rope produced by China patented technology is mainly phosphating with manganese series or zinc-manganese series. Compared with the production process of smooth steel wire rope, only the last wear-resistant phosphating process is added, which greatly improves the wear resistance and corrosion resistance of steel wire rope. Phosphated steel wire is used to directly twist steel wire rope. At present, the fatigue test data show that the fatigue life of phosphating coated steel wire rope is about 3-4 times that of domestic smooth steel wire rope with the same structure and 2-3 times that of imported smooth steel wire rope. With the research of wear-resistant phosphating formula, it may be greatly improved, and it is the most advanced technology in the field of wire rope in the world. Manganese phosphating is wear-resistant phosphating, which can solve the wear problem of steel wire rope in use. Smooth steel wire rope is being eliminated for reference only.
