What is phosphate coated wire rope

What is phosphate coated wire rope

The patented technology of phosphating coated wire rope, also known as manganese-based phosphating wear-resistant coated wire rope, referred to as phosphating steel wire rope, phosphating the rope-making steel wire, the phosphating film makes the surface of the steel wire more wear-resistant and improves its anti-corrosion ability. The porous structure of the phosphating film can increase the amount of grease stored 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, and greatly extend the use of coated wire rope life.

Coated wire rope

Abrasion is the most common damage method of steel wire rope, which is generally divided into three situations: external wear, deformation wear and internal wear. For coated wire rope products, in order to prolong the service life of the coated wire rope, when the fretting between the wires cannot be eliminated, technical measures can only be taken to prevent the wear caused by the fretting. Fretting fatigue damage is closely related to the surface properties of the material. The use of surface engineering technology can improve the anti-fretting fatigue performance of traditional materials and enhance the fretting fatigue resistance of new materials; the use of surface modification methods can effectively improve the anti-fretting damage performance of the material, increase the wear resistance, and improve the resistance to micro-motion Dynamic damage performance. Taking these surface protection measures will help weaken or block the damage caused by the frictional force during the relative sliding between the steel wires, thereby inhibiting and delaying the occurrence of fretting damage on the steel wire surface, and greatly extending the service life of the wire rope.

Phosphate film itself has good electrical insulation, which can effectively inhibit the formation of micro-batteries on the surface of steel wire; the combined effect of phosphate film and grease can greatly improve the lubrication effect between steel wires and the corrosion and oxidation resistance of steel wires. The patented technology of phosphating coated wire rope is to phosphating the rope-making steel wire and control the film weight between 3g/m2-60g/m2, including carbon steel wire, alloy steel wire, galvanized steel wire rope, Zinc aluminuim steel wire rope , Zinc aluminum alloy wire rope, etc.
