Abstract
A coated component for use in a fluid energy device includes a coating system with multiple layers of coating material, including a soft material such as a polymer coated over a hard material such as a metal. The fluid energy device can be a fluid motor or fluid pump, and the coated component can be a rotor or a stator. The hard and soft materials may be interlocked with each other and/or with an interposed porous layer. The presence of the soft material can reduce or eliminate the need for meticulous polishing operations typically required with as-applied hard materials while improving the longevity of mating fluid energy device components. The mating components are exposed only to the soft material in the initial stages of operation, after which the soft material wears away to gradually expose the mating components to the hard material in a less abrasive manner.
