Manganese phosphating film has been used in machining industry for more than 100 years, and its main function is to improve the wear resistance and corrosion resistance of steel materials. For example, the steel gear surface of the gearbox of our car is treated with manganese phosphating coating, which improves the wear resistance and corrosion resistance of the gear surface and ensures that the gear will not be damaged after more than ten years of use. This shows that manganese phosphating film treatment can improve the wear resistance and corrosion resistance of steel materials. The patented technology of phosphating coated wire rope also uses the above principle to extend the fatigue life of 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 manufacturing in the world. The service performance of phosphating coated wire rope far exceeds that of all kinds of smooth wire ropes, and all smooth wire ropes are being eliminated. Wire rope users must choose the wire rope with the longest service life, which is certain. If no users need smooth wire ropes, they will be eliminated.
