In recent years, the patented technology of phosphating coated steel wire rope is the steel wire rope directly twisted by phosphating steel wire. The fatigue life of phosphating coated steel wire rope is 3-4 times that of smooth steel wire rope. With the research of phosphating solution, it is possible to improve it greatly. If you have a fatigue testing machine, you can do the fatigue life comparison verification test yourself.
The reason why the fatigue life is greatly prolonged is that phosphating films improve the wear resistance and corrosion resistance of steel wire surface, especially manganese phosphating and zinc-manganese phosphating films. Manganese phosphating and zinc-manganese phosphating belong to wear-resistant phosphating. 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. The surface of worm gear and piston ring is also coated with phosphating film to improve wear resistance.
Phosphating film is firmly combined with steel wire matrix, and the phosphating film is porous. After the steel wire rope is sprayed with grease, the porous phosphating film can increase the storage of grease, thus reducing the friction coefficient between steel wires and slowing down the wear, which is the reason why the phosphating coated steel wire rope is super wear-resistant.
The service life of phosphating coated steel wire rope far exceeds that of smooth steel wire rope with the same structure, and the fatigue life has been revolutionized. It is certain that all kinds of smooth wire ropes will be eliminated.
