摘要： A method of protecting slurry handling equipment is presented which involves (a) identifying one or more types of wear events (erosion, abrasion, corrosion) to which a surface of the slurry handling equipment is susceptible during operation; (b) estimating the severity of each type of wear event the surface will experience during operation; and (c) applying one or more of a thermal spray coating comprising a metal carbide or a metal nitride, and an erosion resistant organic coating to the surface. The types and severity of the wear events are predicted using one or more computational fluid dynamics models, and the application of either or both of the thermal spray coating and the erosion resistant organic coating to the surface is predicated on the types of wear events identified and their estimated severity. In addition, slurry handling equipment and components thereof protected using the method are provided.
