Material extends wear-part lives

Wear parts made of a material developed by Cerbide Inc. reportedly last longer than tungsten carbide in wet and dry low-impact applications.

Cerbide Inc., Orchard Park, N.Y., reports that the combination of ceramics and cemented tungsten carbide of Cerbide, a long-wearing polycrystalline tungsten carbide material, handles high levels of abrasion and resists erosion better than tungsten carbide. The lives of lowimpact wear parts, such as nozzles and valves, made from this material reportedly increase more than 200 percent.

Cerbide says that, in tests, the material outlasted others it went up against. For example, Cerbide resisted dry erosion and lasted 21 longer than tungsten carbide and twice as long as boron carbide. During wet-erosion tests, the material lasted 17 longer than its closest competitor, cobalt-tungsten carbide.
