The wear resistance of traditional vinyl coating systems has been compared with polymer substit value composite coatings, fiber polymer coatings and ultra-high molecular weight polyethylene (UHMWPE).
wear-resistant coating adds durability to steel waterworks, especially those with debris and aluminum in flowing water.
increasing demand for wear-resistant coatings for abrasives that increase the durability of steel-water structures, especially for structures with debris and alternating wet/dry
. These coating systems not only provide corrosion and chemical resistance to metal surfaces, but also provide good corrosion and wear resistance, and these metal surfaces are often exposed to flowing water containing sand particles and debris. Typically, vinyl coatings are used on hydraulic steel structures to protect them from corrosion and wear.
, however, the coating wears out at a faster rate due to the presence of high water and debris, resulting in significant maintenance and repair costs. In a new study, the wear resistance of conventional vinyl coating systems currently used by the U.S. Army Corps of Engineers in lock and dam steel structures has been compared with polymer-based composite coatings, fibrous polymer coatings, and ultra-high molecular weight polyethylene (UHMWPE).
The performance of ultra-high molecular weight polyethylene and polymer-ceramic composite coatings is significantly better
six coating systems were evaluated by two-body wear tests using receding grinders in dry and wet conditions. In addition, the wetting of coating system under water presence and its effect on wear rate are studied. In addition, the wear trajectories of different coatings were studied by scanning electron microscopes to study and determine their failure.
results, it was found that the performance of ultra-high molecular weight polyethylene and polymer-ceramic composite coatings was significantly better than that of traditional vinyl coatings.
