Abstract
In a pumping system, a PEEK composite material may be applied to wear areas on internal components. Typically, the internal component provides a metallic substrate which is prepared with a metallic bonding layer arc sprayed onto its surface, at least at the wear area. A powderized PEEK composite material is heated and propelled against the substrate and bonding layer by a high velocity oxy fuel technique. This uniformly coats the substrate providing a durable wear surface for prolonging component life.
