The failure process of steel wire rope is the comprehensive action of wear, corrosion and fatigue, which eventually leads to the scrapping of steel wire rope. Wire ropes that are easy to rust and wear must have a short service life, and wire ropes that are not easy to rust and wear must have a long service life.

In order to prolong the service life of steel wire rope of wharf bridge, it is suggested to use manganese phosphating coated steel wire rope and replenish lubrication regularly, which has a service life far exceeding that of imported steel wire rope. For users, the longer the service life of wire rope, the better. For lifting equipment used in atmospheric environment, it is recommended to use manganese phosphating coated steel wire rope, which is directly twisted by phosphating steel wire. Manganese or zinc-manganese phosphating can greatly improve the wear resistance and corrosion resistance of steel wire surface, inhibit fretting wear and corrosion, and thus greatly improve the service life. The fatigue life test data show that the fatigue life of phosphating coated steel wire rope is 3-4 times that of smooth steel wire rope with the same structure. The surface of steel gear of automobile gearbox is phosphatized by manganese series, which can ensure the gear to work normally for more than ten years. It can be seen that manganese phosphating film can effectively improve the wear resistance of gears, and the most common failure reason of gears is wear. There are many papers about phosphating coated wire rope on the Internet, which can be downloaded for free.
