Patented technology of phosphated coated steel wire rope, referred to as phosphated steel wire rope, phosphates the rope-making steel wire. The phosphated film makes the surface of the steel wire more wear-resistant and improves its anti-corrosion ability. The phosphated film has a porous structure It can increase the storage amount of grease on the surface of the rope-making steel wire, reduce the friction factor and promote sliding, delay the occurrence of fretting damage on the surface of the steel wire, inhibit the initiation of fatigue micro-cracks, thereby greatly extending the service life of the steel wire rope. Phosphating technology is mainly used to prevent corrosion of steel materials, reduce friction in cold working, improve wear resistance, bond intermediate phases, electrical insulation and surface decoration, etc. Among them, the phosphating treatment process, whose main functions are to improve the wear resistance of steel materials, reduce friction, and improve lubrication, is widely used in friction-bearing parts in the fields of automobiles, light industry, chemical industry, electrical appliances, and national defense. Phosphating technology is applied to the wear resistance, friction reduction and rust prevention of steel wires in steel wire ropes. The combined effect of phosphating film and grease on the surface of the steel wire is far better than any kind of grease currently in use. Wear is the most common way of damage to steel wire ropes, and is generally divided into three types: external wear, deformation wear and internal wear. For wire rope products, in order to extend the service life of the wire rope, when the fretting between the steel wires cannot be eliminated, technical measures can only be taken to prevent wear caused by fretting. Fretting fatigue damage is closely related to the surface properties of materials. Surface engineering technology can be used to improve the anti-fretting fatigue performance of traditional materials and enhance the fretting fatigue resistance of new materials; surface modification methods can effectively improve the material's resistance to fretting damage, improve wear resistance, and improve micro-fatigue resistance. Dynamic damage performance. Taking these surface protection measures will help weaken or block the harm caused by the friction force when the steel wires slide relative to each other, thereby inhibiting and delaying the occurrence of fretting damage on the steel wire surface, and greatly extending the service life of the steel wire rope.
