ABSTRACT:
An erosion resistant surface is provided for pump components, valves, fluid conduits, diffusion chambers, fluid cleaners, and the like, wherein the surface is exposed to high velocity flow of a fluid containing abrasive particulates. Sharply increased erosion life of such surfaces can be obtained by providing a plurality of closely spaced depressions in the surface, with each depression having a depth in excess of its width, and then applying an erosion resistant coating to the remaining original surface and all surfaces of the depressions.
